Frost Death Knight DPS Spell List and Glossary — Midnight Pre-Patch (12.0)

If you are new to Frost, this is a great place to start to get an understanding of how the spec works. On this page we will discuss what abilities you have, what they are used for within the specialization, how they interact with each other and also with important cooldowns. If you already have experience with Frost and are comfortable with it in the current expansion, it is recommended you skip this section and move on to the rest of the guide.

TCHow much is the Killing Machine proc rate increased for 2H?

The effective proc rate of Killing Machine is ~50% for dual-wield and 100% for 2H with Might of the Frozen Wastes. Dual-Wield still gets 38% more natural procs.

Runic Power and Runes are your two primary resources. We have 6 Runes in total that passively generate over time, taking 10 seconds to recharge (decreased by haste). Runes are the most common resource we use for our abilities, which include Obliterate and Frostscythe. Spending Runes generates 10 Runic Power per Rune used. We use Runic Power as our spender on abilities such as Frost Strike and Glacial Advance

Spells and passive abilities are unlocked as you level up and spend talent points. This page will simply list every single active and passive ability you can obtain, not recommending any specific talent setups or rotations to use. If you want to understand which abilities are best to pick up when leveling, please follow the below link.

These are the abilities that you obtain without selecting anything in the talent trees.

Ability	Level Learned	Abbreviation	Description/Effect
Death Coil	8	DC	Costs 30 Runic Power to cast, dealing Shadow damage to the target. It can be cast on an Undead ally (including yourself) to heal it. Extends the duration of your active plagues on the target by 1.5 seconds. This is your main Single Target Runic Power spender.
Death and Decay	8	DnD	Costs 1 Rune and places a damaging area at the target location, which persists for 10 seconds. Can be used as a DPS ability when combined with talents such as Desecrate and/or as a slow utility when used with Grip of the Dead.
Rune Strike	8	-	Costs 1 Rune and deals moderate damage. This is replaced with Obliterate once we pick up this talent (usually at level 13 or 15).
Death Grip	8	-	Pulls your target towards you. It also has a shorter GCD compared to normal spells at 0.5 seconds. This means that you can quickly use another ability after gripping something.
Death Gate	8	-	Summons a gate that will teleport you to Acherus. Here you can Runeforge your weapon, practice your rotation on target dummies, and change the appearance of your Summon Gargoyle to a Valkyr. Using the Death Gate again will bring you back to your original location.
Runeforging	8	-	Allows you to apply a powerful Runeforge to your weapon, acting as a (usually) better enchant. You do this in the Acherus Hold at the Runeforges.
Death's Advance	9	DA	Death's Advance when activated, increases your movement speed by 35% and prevents you from being slowed below 100% of your movement speed for 10 seconds. It also grants you immunity from knockbacks. It also has a passive ability that prevents your movement speed from being reduced below 70%. This ability is really useful during any encounter with knockback mechanics, which happens quite frequently.
Lichborne	9	-	Turns you undead for 10 seconds. This makes you immune to charm, fear, and sleep, and grants you 10% leech. You can also activate this ability to break any of these CCs, making it a useful tool if you are accidentally hit by a mechanic that applies such a CC.
Dark Command	9	-	Taunts the targeted enemy, forcing them to attack you.
Mastery: Frozen Heart	10	-	Our Mastery, increasing our Frost damage.
Glacial Advance	10	GA	Costs 30 Runic Power, dealing Frost damage to enemies in a line in front of you. This is our AoE Runic Power spender. Make sure to always angle it properly to maximise the number of targets hit.
Runic Empowerment	11	RE	A passive that gives you a 1.8% chance per Runic Power spent to fully regenerate a Rune. This is helps us maintain our Rotation as our Rune spending generates Runic Power, which when spent generates Runes through this passive (remember that Runes also recharge naturally).
Chains of Ice	13	Chains	Costs 1 Rune and slows your target by 70% for 8 seconds. This is generally your primary way of slowing any given target. Great for when you need to kite dangerous mobs in the open-world or kill a fleeing enemy.
Anti-Magic Shell	14	AMS	Absorbs up to 30% of your maximum health in Magic damage over 5 seconds, generating Runic Power based on the damage absorbed (up to 30 Runic Power maximum). This should be used to mitigate Magic damage throughout the fight, while the added Runic Power will help increase your DPS. It also prevents any magical debuffs from being applied to you. This can be very useful to dodge mechanics!
Dark Succor	18	-	A passive that grants you a free Death Strike whenever you kill an enemy that grants honor or experience. Also increases the healing of the Death Strike by 10%. Importantly, you need to land the killing blow to retrieve the buff, meaning you will not get that many procs in Raids and Mythic+. This passive is really useful while leveling as it allows you to keep yourself healthy as you AoE down big packs of mobs.
Raise Ally	19	-	Costs 30 Runic Power and performs a battle resurrection on a targeted dead ally, bringing them back to life (even in combat).
Remorseless Winter	19	RW	Costs 1 Rune, dealing Frost damage around you for 8 seconds and slowing enemies by 20%. Good AoE ability.
Rime	21	-	Gives Frost Strike and Glacial Advance have a 45% chance to empower your next Howling Blast, making it free of cost and dealing significantly more damage. You pretty much only use Howling Blast when you have this proc.
On a Pale Horse	22	-	A passive that grants 20% mounted movement speed. Nice speed boost, especially in areas where flying is disabled.
Path of Frost	27	-	Costs 1 Rune and grants everyone in your group the ability to walk on water. Breaks on any damage taken. Has some niche use-cases and allows you to prank your party members when your group is jumping down into water...

Ability	Abbreviation	Description/Effect
Icebound Fortitude	IBF	Provides a 30% damage reduction for 8 seconds, additionally making you immune to stuns. It can be used when stunned as well to break out of the CC. Primary defensive cooldown for us with the added benefit of the stun break!
Death Strike	DS	Costs 45 Runic Power (35 with Improved Death Strike) and constitutes our primary means of healing ourselves. The amount of healing increases with the damage we've taken in the last 5 seconds, making it excellent to use after you have taken a big hit. It heals for 20% of the damage taken with a minimum of 7% max hp healed every time (32% and 11.2% with Improved Death Strike).
Raise Dead	-	Summons a pet to fight by our side for 1 minute. Deals very little damage and has low value.
Mind Freeze	-	Interrupts your target. It has a 15 yards range, a benefit over other melee interrupts that often require melee range.
Blinding Sleet	Sleet	Blinds all targets in a cone in front of you for 5 seconds. When the enemies are broken out of sleep via damage or if the duration finishes, they are slowed by 50% for 6 seconds. Great ability to stop a group of enemies from casting, as well as controlling them efficiently. Your tank will love this ability whenever they need to kite.
Wraith Walk	WW	Provides 70% movement speed for 4 seconds. Any ability used during the channel will break the effect. Useful as a movement speed increase in instances when you need to move between A and B without doing anything else.
Control Undead	-	Costs 1 Rune and controls the targeted Undead enemy for 5 minutes. This requires that the enemy is sufficiently low-level (it does not work on bosses and certain mobs in dungeons). Useful as a CC tool and can provide a little bit of damage (since our standard pet is relatively weak).
Death Pact	-	Heals you for 50% of your maximum health, as well as putting a healing absorption heal for 30% of your maximum health. A panic-button heal with a downside. The effective healing is only 20%, but you still find a lot of instances where this provides the required breathing room for your healers or you need to bring you back to health. Can be improved with Death Defiance which reduces the Cooldown by 30 seconds and increases the healing you receive by 50% when the healing absorb is active - a nice boost.
Anti-Magic Zone	AMZ	Places a zone on the ground that reduces magic damage taken by 15% for 6 seconds for everyone standing in it. The cooldown can be decreased to 3 minutes and the duration increased to 8 seconds via the Assimilation talent.
Asphyxiate	Asphyx	Stuns your target for 5 seconds. Simple single-target stun with a range of 20-yards.

Ability	Abbreviation	Description/Effect
Frost Strike	FS	Costs 35 Runic Power, dealing Frost damage to your target. This is our primary Runic Power spender in Single Target, forming part of our Core rotation.
Obliterate	Oblit	Costs 2 Runes, dealing Physical and Frost damage (or pure Frost damage with Killing Machine). Our primary Rune spender and a major part of our core rotation! The damage from this ability is mainly from the consumption of Killing Machine procs. Using it without these procs deals significantly less damage (but is still a part of our rotation).
Howling Blast	HB	Costs 1 Rune, dealing frost damage to your target and nearby enemies. The damage scales as square-root, meaning the damage per target decreases as you add additional targets. The total damage always increases however. This spell also applies our DoT Frost Fever to all targets hit. Frost Fever deals Frost damage over 24 seconds and has a chance to grant you 4 Runic Power every time it ticks. The chance of gaining Runic Power is increased the more target that has the DoT on them. Generally only used with procs of Rime.
Empower Rune Weapon	ERW	Off gcd ability dealing AoE damage and granting you both 40 Runic Power and a stack of Killing Machine. With 2 charges and a 30 seconds cooldown this is out primary way of actively managing our resources. The ability used to have a travel time but is instant in Midnight.
Frostscythe	FsC	Costs 2 Runes and deals Frost damage in a cone in front of you, dealing reduced damage after 5 targets. This ability will critical strike for 4 times its normal damage when consuming Killing Machine procs. This is our Rune spender in AoE scenarios, replacing Obliterate which we use in Single Target.
Pillar of Frost	Pillar/ PoF	Increases your strength by 30% for 12 seconds. Iconic Frost DK cooldown that we leverage to boost our other cooldowns. It has multiple talents that directly interact with it, such as Enduring Strength, Frozen Dominion and Obliteration.
Frostwyrm's Fury	FwF	Calls down a dragon to breath frost damage to all enemies in a line in front of you, traveling 40 yards, stunning enemies for 4 seconds and slowing them by 50% for 10 seconds. Huge burst AoE cooldown that can be leveraged well on extra-large packs in Mythic+ or add spawns in Raid. Really strong synergy with Rider of the Apocalypse due to Apocalypse Now as well as our Apex Talents.
Breath of Sindragosa	Breath/ BoS	Costs 60 Runic Power (off GCD) to deal Frost damage in a cone in front of you every second for 8 seconds. Consuming Killing Machine or Rime extends the duration by 0.8 seconds. Great synergy with Obliteration due to Killing Machine generation and a strong cleave burst cooldown.

Ability	Abbreviation	Description/Effect
Runic Attenuation	RA	Gives your auto attacks a chance to grant you 3 Runic Power. This provides around 30 Runic Power per minute, adding a good amount of resources to our rotation.
Improved Death Strike	-	Increases the healing of Death Strike by 60% and lowers its cost by 10 Runic Power. Effectively makes Death Strike a 35 Runic Power ability that heals for a minimum of 11.2% max health, or 32% of damage taken in the last 5 seconds, whichever is greatest.
Cleaving Strikes	-	Frostscythe deals 20% increased damage when Remorseless Winter is active. Nice boost that has a small impact on our Obliterate vs Frostscythe priority.
Gloom Ward	GW	Increases the effectiveness of all absorbs on you by 15/30%. Big survivability increases both from empowering our abilities, such as Anti-Magic Shell, as well as any healing coming in the form of absorbs. Especially good with Disc Priests!
March of Darkness	-	Grants you an extra 25% movement speed during the first 3 seconds of activating Death's Advance.
Unholy Momentum	-	Provides 2%/4% haste passively.
Enfeeble	-	Gives your ghoul a chance to apply a debuff to its target, reducing its movement speed by 30% and making it deal 15% less damage to you. A nice passive defensive gain for us and a good reason to cast Raise Dead.
Coldthirst	-	Grants you 10 Runic power and reduces the cooldown of Mind Freeze whenever you successfully interrupt using the ability. A nice addition to our resource generation, as well as providing overall more interrupt opportunities in any situation.
Proliferating Chill	-	Increases the number of targets hit by your Chains of Ice from 1 to 2. It only affects additional enemies in close proximity of your primary target and lacks many uses in PvE.
Permafrost	-	Provides a shield on yourself based on 30% of your auto attack damage. Provides a good deal of tankiness, both from passive absorption but also as prevention to one-shot mechanics.
Veteran of the Third War	VoTW/ Veteran	Increases your stamina by 12%, making you tankier overall.
Brittle	-	Grants your diseases ( Frost Fever) a chance to apply a debuff to your enemy, increasing the damage you do against them by 6% for 5 seconds.
Blood Bond	-	Your primary pet sacrifices 4% of its maximum HP to heal you for 1% of yours every second when you are below 50% health. Solid self-heal gain!
Icy Talons	IT	Provides a 6% increase in attack speed for 10 seconds every time we spend Runic Power, stacking up to 3 times. Scales well with Killing Machine that procs off critical auto attacks.
Death Notes	-	Reduces the cost of Raise Ally by 30, making it free. Nice quality of life talent that helps you react faster to player deaths when you would otherwise lack the Runic Power.
Death Defiance	-	Reduces the Cooldown of Death Pact and increases the Healing you take when the healing absorb shield is active by 50%. Significant buff to Death Pact with more frequent uses and a smaller negative effect as you effectively only need to heal up 20% of your effective health down from 30%.
Unholy Bond	-	Increases the effectiveness of our Runeforges by 20%. This includes every aspect of the Runeforge, making Rune of the Fallen Crusader both increase its healing and strength gain, for instance.
Ice Prison	-	Chains of Ice now also roots enemies for 4 sec but its cooldown is increased to 12 sec.
Death's Reach	-	Increases the range of Death Grip by 10 yards and resets its cooldown whenever you kill an enemy granting experience or honor. Useful in any situation where you need to grip adds as the extra range both helps with the distance, you can move them, as well as lowering how far you need to run yourself. The cooldown reset is mostly useful during leveling, as you need to land the killing blow to gain the effect.
Assimilation	-	Reduces the cooldown of Anti-Magic Zone by 1 minute and increases its duration by 2 seconds.
Anti-Magic Barrier	-	Lowers the cooldown of Anti-Magic Shell to 40 seconds and increases the amount absorbed by 40%. Useful for any situation with heavy magic damage or frequent magic debuff applications (that you can then ignore).
Grip of the Dead	-	Adds a 90% slow to your Death and Decay, reducing by 10% for every second. A great tool to help your tank kite and manage any trash pack, making Death and Decay a somewhat useful ability.
Suppression	-	Passively increases your Avoidance by 3%. This is increased to 9% for 6 seconds when you suffer a loss of control effect.
Blood Scent	-	Passively increases your Leech by 3%.
Unholy Endurance	-	Adds 2 seconds to the duration of Lichborne and decreases its Cooldown by 30 seconds. A small defensive gain to the Cooldown.
Osmosis	-	Your Anti-Magic Shell also increases healing received by 15% when it is active.
Insidious Chill	-	Applies a stacking debuff with your auto attacks, reducing the enemy's attack speed by 5% per stack up to 20% at 4 stacks. Helps your tanks survive in a scenario (or yourself when doing open-world content). Stacks with similar effects such as Curse of Weakness.
Runic Protection	-	Reduces your chance to be critically struck by 3% and increases your armor by 6%. Small defensive boost.
Blood Draw	BD	Heals you for a moderate amount if you drop below 30% health. It can only occur once every 2 minutes. Also reduces damage taken by 10% and Runic Power cost of Death Strike by 10 for 8 seconds after it triggers.
Rune Mastery	-	Makes spending Runes give a chance to increase our strength by 3/6% for 8 seconds.
Subduing Grasp	-	When you pull an enemy with Death Grip, they deal 6% less damage to you for 6 seconds. Makes Death Grip a small defensive Cooldown against bosses and other enemies.
Will of the Necropolis	WotN	Reduces the damage you take below 30% by 20/35%. Big boost to our survivability since the damage we take below 30% is by far the most useful to mitigate. Effectively increases max HP by 16% against one-shots.
Null Magic	-	Reduces magic damage taken by 5% and harmful debuff duration by 35%. A really nice defensive boost against magic damage.
Unyielding Will	-	Increase the cooldown of Anti-Magic Shell by 20 seconds but makes it remove all negative debuffs on you when used. Can be incredibly powerful when dealing with various raid mechanics but requires a good use case to justify the 20 seconds cooldown increase.
Death's Echo	DE	Provides an extra charge to Death's Advance, Death and Decay and Death Grip. Nice increase in utility with the extra mobility and the additional grip.
Vestigial Shell	-	Anti-Magic Shell also applies two shields to nearby allies. These shields absorb some Magic Damage (10% of your own AMS) and reduces the duration of Magic effects by 50%. Nice defensive boost to your party, especially in Mythic+.

Ability	Abbreviation	Description/Effect
Killing Machine	KM	Gives your critical auto-attacks a chance to make your next Obliterate or Frostscythe a guaranteed critical strike (Frostscythe crits for 4x normal damage when consuming Killing Machine). Also makes Obliterate do pure Frost damage, significantly empowering it as well. It has built-in bad-luck-protection with an increasing probability of getting a proc every time you fail to get one. The chance scales as 30% -> 60% -> 90% -> 100%, meaning you cannot have more than 3 crit auto-attacks in a row without getting a proc! For 2H, the probability is 100% when you get a crit auto. Proc stacks up to two times and makes Obliterate do Frost damage.
Arctic Assault	-	Consuming Killing Machine fires a Glacial Advance through your target at 60% effectiveness. Adds a nice damage boost to consuming Killing Machine but also helps maintain Razorice via the Glacial Advances being fired.
Runic Overflow	-	Increases Frost Strike and Glacial Advance damage by 10/20%.
Frostbound Will	-	Consuming procs of Rime reduces the Cooldown of Empower Rune Weapon. A nice added priority to procs of Rime to incentivise spending them. Also helps our resource economy.
Runic Command	-	Increases maximum Runic Power by 10/20 and Rune regeneration rate by 8/15%. Nice boost to how much Runic Power we can hold, helping us avoid overcapping. Also provides extra Runes for our resource economy.
Biting Cold	BC	Increases the damage of Remorseless Winter by 35% and generates a proc of Rime when Remorseless Winter has dealt damage to three unique targets. Big boost overall with the most impact in AoE. Both from the raw damage as well as the guaranteed Rime proc!
Inexorable Assault	IA	Provides a stacking buff (up to 5 times) on yourself every 4 seconds. Obliterate and Frostscythe consume up to 3 stacks, dealing additional Frost Damage per stack. Importantly, the extra Frost damage is independent of whether Obliterate or Frostscythe crits and does not synergizes with any procs of Killing Machine. For Frostscythe, it only hits your primary target, not gaining any benefit from the AoE part of the ability.
Frostreaper	-	Obliterate deals 10% increased damage and and has a change to tether a nearby enemy to your target. Frost Strike severs the tether, dealing shadowfrost damage to both enemies. Adds incentive to use both Obliterate and Frost Strike in 2-target cleave scenarios with this talent.
Icy Onslaught	-	Frost Strike and Glacial Advance causes your next Frost Strike or Glacial Advance to deal 15% increased damage and cost 5 more Runic Power. Continues stacking until the next proc of Runic Empowerment. Effectively increases both cost and damage of your Runic Power abilities while reducing the amount of resources you have in your rotation.
Gathering Storm	GS	Increases the duration of Remorseless Winter by 0.5 seconds, and its damage by 10% for every Rune you consume. This stacks to 10. With sufficient Rune use, you can extend this buff for 20 seconds when your Remorseless Winter becomes available. Recasting the ability with retain the stacks and reset the duration to 8. This is a significant DPS increase and is something you should aim to do when possible.
Murderous Efficiency	ME	Gives a 20% chance to generate a Rune when you consume a proc of Killing Machine. Nice resource talent that has strong synergy with both Obliteration as well as high Crit Rating due to the increase in Killing Machine procs being generated.
Rage of the Frozen Champion	RotFC	Frost Strike and Glacial Advance has a 15% increased chance to trigger Rime. Furthermore, consuming procs of Rime generates 8 Runic Power. Primarily a resource talent due to the free Howling Blasts in your rotation and the Runic Power generation.
Enduring Strength	-	Provides a 8% strength buff after your Pillar of Frost buff fades. The base duration is 6 seconds, and every Obliterate and Frostscythe critical strike extends this by 2 seconds up to 20 seconds. Extends the buff window and synergises well with our longer cooldowns such as Breath of Sindragosa.
Frozen Dominion	-	Pillar of Frost now summons a Remorseless Winter that lasts for 4 seconds longer (12 seconds total). Each enemy hit by Remorseless Winter grants you 8% Mastery up to a maximum of 40% for 15 seconds. This passive replaces your active Remorseless Winter ability and simplifies the rotation. Puts more emphasis on your Pillar window as you will not have Remorseless to cast outside of it.
Frigid Executioner	-	Runic Empowerment has a 25% chance to refund an additional 1 Rune. A pure resource talent that improves the effectiveness of our Runic Empowerment passive.
Howling Blades	-	Consuming Rime deals additional frost damage to the target and has a 15% chance to trigger Killing Machine. A talent that puts more emphasis on Rime and increases the number of Killing Machine procs you generate.
Cryogenic Chamber	CC	Consuming Rime stores 15% of the damage dealt into your next Remorseless Winter, up to 20 times. Another Rime talent that makes you want to consume the proc with a higher priority.
Everfrost	EF	Applies a debuff to any enemy damaged by your Remorseless Winter, increasing the damage they take from Remorseless Winter by 6% for 8 seconds, stacking up to 10 times. Also increases the damage done by Howling Blast to secondary targets by 50% when empowered by Rime. In a similar way to Gathering Storm, this debuff can be extended at 10 stacks with sufficient extension of Remorseless Winter. You have slightly more leeway here and only need to extend Remorseless Winter by 5 seconds to roll the debuff.
Northwinds	-	Howling Blast now hits an additional target at 100% effectiveness. Rime increases Howling Blast damage by an additional 75%. A nice boost to Howling Blast and a significant increase to how much the ability does in AoE.
Bonegrinder	-	Provides a stacking 1% critical strike buff whenever you consume a proc of Killing Machine. The buff lasts for 10 seconds. Using a proc of Killing Machine at 5 stacks consumes the buff, granting 10/20% increased Frost damage for 10 seconds. Great synergy with Obliteration that is almost guaranteed to trigger this buff after each Pillar of Frost window.
Smothering Offense	-	Increases auto-attack damage by 10%. Also increases the number of times that Icy Talons can stack by 2, thus increasing the proc rate of Killing Machine and other talents that synergise with auto attack hits.
Avalanche	-	Provides some extra AoE damage whenever we consume a proc of Rime, as well as applying a stack of Rune of Razorice to all targets hit. A nice additional damage boost to Rime as well as an increase in Razorice generation.
Icebreaker	-	Makes your Rime also grant 30/60% increased damage to your primary target. Makes Howling Blast hit hard on single-target and increases the priority of not overlapping procs of Rime.
Obliteration	Oblit	During Pillar of Frost, your Frost Strike, Glacial Advance and Howling Blast generate a proc of Killing Machine and have a 20% chance to generate a Rune. Overall, it adds a significant amount of procs to your rotation and converts your Pillar of Frost window into a big damage cooldown. Introduces a "weaving" game style where you alternate between generating and consuming procs of Killing Machine.
Icy Death Torrent	IDT	Your auto attack crits have a chance to deal Frost damage in a cone in front of you. Good passive damage throughput that requires you to always think about your position to deal effective AoE damage.
Shattering Blade	SB	Makes your Frost Strike consume your Rune of Razorice debuff at 5 stacks, increasing its damage by 100%. Makes Frost Strike sometimes hit hard, but does give us a period of Rune of Razorice downtime whenever we utilize this effect. Essentially requires us to Runeforge Rune of Razorice to be useful. Frostbane consumes all stacks on your main target to deal an additional 300% damage.
Hyperpyrexia	-	Runic Power abilities sometimes deal 45% of their damage over 4 sec. Just a passive DPS boost to any ability that consumes Runic Power. This includes the free Glacial Advance you get from Arctic Assault.
Killing Streak	-	Obliterate and Frostscythe consume all stacks of Killing Machine to deal 25% increased damage and grant a stacking 1.5% Haste buff for 8 seconds for each stack consumed. This means that you can now consume two stacks of Killing Machine at once for a 25% damage boost. This helps your resource economy as your end up less heavy on Rune consumption and can instead focus on Runic Power and Rime procs.
The Long Winter	TLW	During Pillar of Frost, auto-attack critical strikes increase the duration by 1 second, up to 4 seconds. Even more value for crit autos, increasing the value of Crit and Haste for us.
Frostbane	-	Each enemy hit by your Glacial Advance has a chance to transform your next Frost Strike into Frostbane (chance increases with number of stacks of Razorice on the target). Frostbane hits all enemies in front of you, reducing in damage by 5% down to 40% for each additional foe. This makes Frost Strike a much more frequent button in AoE as your Glacial Advance from Arctic Assault will proc Frostbane lots. Frostbane also deals 300% additional damage to the primary target.

The apex talents are available to learn as you level up from 80 to 90.

Ability	Abbreviation	Description/Effect
Chosen of Frostbrood		Frostwyrm's Fury deals 100% increased damage to the first enemy it hits and grants you 15% Haste for 12 seconds. Significantly empowers Frostwyrm as a Cooldown and makes it mandatory when you talent into the Apex talents.
Chosen of Frostbrood		Frostwyrm's Fury extends the duration of an active Pillar of Frost by 2/4 seconds and grants Enduring Strength an additional 4/8% strength. Heavily incentivises using Frostwyrm inside of your Pillar of Frost, clarifying its usage that has been more complicated in the past.
Chosen of Frostbrood		All Frost damage increased by 10% and Frostwyrm's Fury deals 100% increased damage. Furthermore, you can recast Frostwyrm to recall it at 50% effectiveness.

Ability	Abbreviation	Description/Effect
Rider's Champion	-	Spending Runes have a chance to summon a Horsemen for 10 seconds. Randomly gets one out of four Horsemen: Mograine - Casts Death and Decay that follows his location around. Whitemane - Casts Undeath on your enemy, a stacking DoT that can also spread to nearby enemies, similar to Necrotic Plague of old times. Trollbane - Casts Chains of Ice on your target, slowing their movement speed and increasing the damage you deal to them. Trollbane's Icy Fury allows you to burst the chains, dealing heavy AoE damage. Nazgrim - Increases your strength by 3% when active. Nazgrim's Conquest can significantly increase this benefit.
On a Paler Horse	-	While outdoors, you are able to mount your Acherus Deathcharger in combat. Huge increase to the speed at which you can quest in outdoor content. Unfortunately does not work in instanced content such as Raids, Dungeons, Battlegrounds and Arenas.
Death Charge	-	Replaces your Death's Advance, increasing the movement speed you gain to 100% and mounting you for its duration. Breaks you free of any movement impairment effects when used. Furthermore, allows you to keep fighting while on the mount. Immune to knockbacks when in effect.
Whitemane's Famine	-	When Obliterate or Frostscythe damages a target affected by Undeath it gains 1 stack and infects another nearby enemy. Allows you to quickly spread debuff in AoE via Frostscythe.
Hungering Thirst	-	The damage of your diseases and Frost Strike are increased by 10%.
Mograine's Might	-	Your damage is increased by 5% and you gain the benefits of your Death and Decay while inside Mograines Death and Decay. Importantly, the 5% damage increase only comes from Mograine's Death and Decay, not your own so keep an out for when Mograine spawns and stand on top of him!
Nazgrim's Conquest	-	Apocalyptic Conquest's strength is increased by 3% every time an enemy dies while Nazgrim is active. Furthermore, each Rune you spend increases the Strength by 1%. Very powerful for packs of mobs where weaker ones die quickly and early.
Fury of the Horsemen	-	Every 50 Runic Power you spend extends the duration of the Horsemen currently aiding you by 1 second, up to a maximum of 5 seconds. Solid way of improving overall uptime of the Horsemen!
A Feast of Souls	-	While you have 2 or more Horsemen aiding you, Runic Power spending abilities deal 20% increased damage. Good synergy with Apocalypse Now but also have good uptime outside of our main cooldown windows.
Horsemen's Aid	-	When active, your Horsemen will occasionally cast Anti-Magic Shell on you at 80% effectiveness. Great for extra Magic immunity and absorb.
Pact of the Apocalypse	-	When you take damage, 5% is redirected to each active Horseman. Solid passive damage reduction that increases significantly during your cooldowns.
Trollbane's Icy Fury	-	Obliterate and Frostscythe shatters the Chains of Ice cast by Trollbane, dealing damage to all nearby enemies and slowing them.
Mawsworn Menace	-	Obliterate deals 5% more damage and your Remorseless Winter lasts 2 seconds longer.
Ride or Die!	-	Pillar of Frost summons forth Trollbane for 6 seconds.
Let Terror Reign	-	Casting Obliterate or Frostscythe orders Whitemane to cast her own versions at 100% effectiveness as well.
Unholy Armaments	-	The abilities that the Horsemen cast deal 5% increased damage.
Apocalypse Now	-	Frostwyrm's Fury calls upon all 4 Horsemen to aid you for 20 seconds. This creates heavy synergy with Frostwyrm's Fury and Rider.

Ability	Abbreviation	Description/Effect
Reaper's Mark	-	2 Rune, 45 seconds cooldown ability that deals Shadowfrost damage and applies the Reaper's Mark debuff when used. Every time you deal Shadow or Frost damage, one stack is added to the 12 seconds debuff. After 12 seconds or when reaching 40 stacks, it explodes and deals damage per stack. If the target dies, it travels to another nearby enemy. Big ability that we time with our Pillar of Frost window.
Wave of Souls	-	Casting Reaper's Mark sends a wave through the enemy that returns to you, dealing Shadowfrost to enemies in its path. Critical strikes from the wave increases the Shadowfrost damage that the enemy takes for 15 seconds, stacking twice. The returning wave always critically strikes, so you are guaranteed at least one stack of the damage debuff.
Soul Rupture	-	When Reaper's Mark explodes, 20% of the damage is dealt to nearby enemies. Helps to add AoE value to the ability.
Swift and Painful	-	If no enemies are struck by Soul Rupture, you gain 5% strength for 8 seconds. Wave of Souls is 50% effective on the main target of your Reaper's Mark. This talent ensures that you still get Single Target value from talents that are otherwise primarily focused on AoE!
Wither Away	-	Frost Fever deals its damage 100% faster and the second scythe from Exterminate applies Frost Fever. Essentially doubles the DPS you get from you Frost Fever DoT.
Grim Reaper	-	Reaper's Mark also grants a charge of Killing Machine. Reaper's Mark also deals up to 30% increased damage based on your target's missing health. The free Killing Machine makes it much nicer to use with Pillar of Frost and the second effect gives us a bit of execute oomph.
Dark Talons	-	Consuming Killing Machine or Rime has a 25% chance to grant three stacks of Icy Talons and increase the maximum stack count by the same amount for 6 seconds. Great synergy with Killing Machine proc chance, Icy Death Torrent, Smothering Offense and The Long Winter to name the most obvious talents. Furthermore, abilities that spend Runic Power count as Shadowfrost damage, synergising well with Bind in Darkness.
Reaper's Onslaught	-	Reduces the cooldown of Reaper's Mark by 15 seconds but the amount of Obliterates empowered by Exterminate is reduced by 1. Brings you to a 30 seconds cooldown cycle which do not fit your 45 seconds Pillar of Frost window.
Bind in Darkness	-	Shadowfrost damage applies two stacks to Reaper's Mark and four stacks when it is a critical strike. Furthermore, Rime empowered Howling Blast deals Shadowfrost damage as well as 60% more damage overall. Big synergy with Dark Talons that make all our Runic Power spenders Shadowfrost damage.
Pact of the Deathbringer	-	When you suffer damage of more than 25% of your max health, you instantly cast Death Pact at 50% effectiveness. Can only occur every 2 minutes. When Reaper's Mark explodes, the cooldowns of this effect and Death Pact are reduced by 5 seconds. Some useful defensive ability with instant heal on big hit. The cooldown reduction brings the cooldown of Death Pact down to 1 minute 50 seconds, from 2 minutes, so not a very strong effect.
Rune Carved Plates	-	Each Rune spent reduces the magic damage you take by 1.5% and each Rune generated reduces the physical damage you take by 1.5% for 5 seconds, up to 5 times. Provides a solid amount of defensive value as you tend to maintain high stacks for most of fights.
Death's Messenger	-	Reduces the cooldown of Lichborne and Raise Dead by 30 seconds. Some extra defensive value due to Lichborne being an okay defensive cooldown. Furthermore, a small DPS upgrade due to Raise Dead lower cooldown.
Expelling Shield	-	When an enemy deals direct damage to your Anti-Magic Shell, their cast speed is reduced by 10% for 6 sec. Generally useless for DPS Death Knights.
Frigid Resolve	-	Permafrost is 50% more effective.
Deathly Blows	-	Frost Strike and Glacial Advance damage are increased by 5%. Reaper's Mark grants 3 stacks of Bonegrinder, helping to gain the buff quickly in your Pillar of Frost window.
Echoing Fury	-	Reaper's Mark deals 5% increased damage. Furthermore, Frostwyrm's Fury grants two stacks of Exterminate at 100% effectiveness. Allows you to generate lots of free Killing Machine's in your Pillar window.
Exterminate	-	After Reaper's Mark explodes, your next two Obliterates summon two scythes to strike your enemies. The first scythe deals Shadowfrost damage and has a 100% chance to grant a stack of Killing Machine. The second scythe deals AoE damage around your target and applies Frost Fever with Wither Away. This fits nicely into your Pillar of Frost as you get free Killing Machine procs to spend with the damage increase..
