On this page, you will find out the best PvE talent choices and builds for your Demonology Warlock in WotLK Classic, as well as advised glyphs.


Talent Builds for Warlock in Wrath of the Lich King

Warlock does not have too much wiggle room in terms of talents as you need all but two of the points in order to get full value out of your spec. However, you do have two flex points that you can place wherever you choose. I personally choose Mana Feed IconMana Feed and one in Intensity IconIntensity. Some people choose to put them both in Destructive Reach IconDestructive Reach, Intensity IconIntensity or Improved Healthstone IconImproved Healthstone or even Improved Demonic Tactics IconImproved Demonic Tactics and most importantly Suppression IconSuppression.


Important Talents for Demonology Warlocks in Wrath of the Lich King

In this section we will go over some of the key talents you will use when you are playing a Demonology Warlock to better help you understand your most important talents as they are vital to play the build to its fullest strength.

All three of these talents are mandatory in the Destruction tree. These talents will make your Shadow Bolt IconShadow Bolts do much more damage, cast faster and crit for much harder.

This is a popular pick for your two flex points. You should never hesitate to put points into Suppression IconSuppression to make up your hit. And if you're ever wondering if you need hit rating, then I would suggest putting a point or two into Suppresion OVER using Hit Gems.

This just helps keep your pet up, healing your Summon Felguard IconSummon Felguard for 15% of all dmg you deal. This heals your FG comically fast.

increases the attack power bonus of your Summon Felguard IconSummon Felguard's Demonic Frenzy IconDemonic Frenzy by 3%. This is just a nice buff to your Summon Felguard IconSummon Felguard.

This increase the Stamina and Intellect of your Summon Felguard IconSummon Felguard by 15% and increases your max mana by 3%

This increase your Fel Armor IconFel Armor buff by 30% which is massive as it gives you an additional 54 spell power as well as 9% more from the spirit to spell power conversion.

This was changed and no longer gives us bonus damage, but it does transfer 20% of all dmg taken and give it to your Summon Felguard IconSummon Felguard, which is really nice for those times you pull threat on the AoE packs. >

This increases the ratings you gain from your Create Spellstone IconCreate Spellstone and Create Firestone IconCreate Firestone by 300%. In this case as Demonology you only use Create Spellstone IconCreate Spellstone, but to give you a quick example, without this talent, your spellstone gives you 60 Haste rating, whereas with this talent, Create Spellstone IconCreate Spellstone gives you 240 Haste Rating, which is a ton of Haste.

This increases all dmg done by 5% as well as reduces all dmg taken by 5%.

This increases the duration of your Immolate IconImmolate by 9 seconds, but more importantly, your Corruption IconCorruption has a 12% chance to gain the Molten Core IconMolten Core effect for 15 seconds. The Molten Core IconMolten Core effect buffs your next three Incinerate IconIncinerate dmg by 18% and reduces its cast time by 30% OR it buffs your next three Soul Fire IconSoul Fire dmg by 18% and increases its crit chance by 15%.

When you Shadow Bolt IconShadow Bolt, Incinerate IconIncinerate or Soul Fire IconSoul Fire any target at or below 35% health, the cast time of your Soul Fire IconSoul Fire spell is reduced by 40% for 10 seconds and also does not cost a Soul Shard. This is one of the main abilities for Demonology Warlocks as this gives you an execute ability. You should constantly be looking to get Decimation IconDecimation procs off any mobs around you, then use those Decimation IconDecimation procs to cast Soul Fire IconSoul Fire into your main target. This synergizes very well with Molten Core IconMolten Core as the dream is to get your Molten Core IconMolten Core procs while in Decimation IconDecimation.

This will increase your Summon Felguard IconSummon Felguard attack speed by 20% and break all stun, snare and movement impairing effects and makes your Summon Felguard IconSummon Felguard immune to them for 15sec. You should macro this ability into your Shadow Bolt IconShadow Bolt, Seed of Corruption IconSeed of Corruption and your Soul Fire IconSoul Fire.

This gives both you and your Summon Felguard IconSummon Felguard 10% more crit. Allowing you both to crit much more often.

This reduces the cooldown of your Demonic Empowerment IconDemonic Empowerment, Metamorphosis IconMetamorphosis and Fel Domination IconFel Domination by 30%. This lowers the cooldown on 3 pretty important abilities.

This increases your spell dmg by 10%, and your Summon Felguard IconSummon Felguard crits apply the Demonic Pact IconDemonic Pact effect to ALL party or raid members. Demonic Pact increases spell power by 10% of your spell damage for 45 sec. This effect has a 5 sec cooldown and does not work on subjugated demons. This means that when your Summon Felguard IconSummon Felguard crits, it snapshots your current spell power and gives 10% of that to your whole raid. This is the main reason you are brought to the raid.

This spell transforms you into a Demon for 30 seconds. While in Demon form, your armor is increased by 600%, your damage increased by 20% and the chances you’ll be critically hit by melee attacks are reduced by 6% and all durations of stun and snare effects are reduced by 50%. Not only that but you get 4 new abilities that are only available when in Demon form


Best Glyphs for Warlock in Wrath of the Lich King

Glyphs are a new consumable of sorts introduced in Wrath of the Lich King. Glyphs greatly improve certain spells when you learn them, supporting and even enabling some builds. Glyphs are not permanently learned, so you will want to carry multiple glyphs on you so you can change them quickly depending on the raid or boss encounter you are in. Demonology has some really powerful Glyphs that make the gameplay a little more fun.
