Legendary Changes for Patch 9.1
Covenant Legendaries
All specs gained access to four Legendaries in Patch 9.1, with each of them working solely with one — and only one — Covenant.
Abomination's Frenzy
Abomination's Frenzy is the Necrolord Death Knight Legendary, and modifies Abomination Limb in three important ways:
- It makes it last longer, totaling roughly 30% more damage over its duration.
- It also reduces the interval between Runic Corruption proc gains from 6s to 4s (+2 procs overall).
- Finally, whenever it grips a target, your current target gets a debuff making it take 10% additional damage for 12s. This is likely a bug compared to the debuff applying to the gripped target instead.
This is generally quite a weak Legendary. The increased duration is nice and the two extra procs of Runic Corruption works well. However, the Legendary has little value in single-target which is a big issue. The 10% additional damage taken is difficult to leverage and simply does not work on bosses and certain mobs; overall it is a lackluster legendary.
Final Sentence
Hearkening all the way back to early Shadowlands Beta, the Kyrian Legendary is an effect that grants you 2% Strength and refunds a Rune whenever you manage to spread Shackle the Unworthy. The Strength bonus caps at 10%.
With limited value in AoE and zero gain for single-target, this Legendary is simply not a great choice. Sure, you can boost your AoE but it relies on a spread mechanic which is inconsistent. It is, overall, lackluster and not something we would recommend
Rampant Transference
This Legendary is comprised of two distinct effects, even though the tooltip can be misleading:
- While you are in Death's Due, you generate 20% more Runic Power.
- The Death's Due buff lasts 2 seconds longer, and each stack grants 1% more Strength, boosting the total Strength bonus of Death's Due to 12%.
Buffing the strength of Death's Due is not that great, especially since that is not the strong part of the Legendary to start with. Generating extra Runic Power is nice and can give ~20 Runic Power for each use. Overall though, this is not a lot and the Legendary is too undertuned for us to recommend it.
Insatiable Hunger
This Legendary adds a detonation at the end of Swarming Mist, scaling up with the amount of Runic Power you spent during it.
This is a solid AoE Legendary that brings little value in single-target. We can often get a 300%+ damage increase by spamming Epidemic in AoE. However, the damage is only significant once you add multiple targets and is really quite lackluster on single-target. This is not a Legendary we would recommend.
Other Legendary Changes for 9.1
Unlike some other classes, no other Legendaries have been tweaked or reworked.
Conduit and Soulbind Changes for Patch 9.1
In 9.1, all the Soulbinds gained a number of additional rows of Conduits and generic traits, along with a new capstone trait.
To provide a quick summary before the wall of text explaining each trait in detail:
- Kyrian players will likely stick to Pelagos.
- Venthyr players will likely switch to Nadjia the Mistblade for everything.
- Night Fae players likely stick to Niya for everything.
- Necrolord players will likely stick to Bonesmith Heirmir.
Kyrian
Pelagos
Pelagos gains the following Conduits:
- An additional Potency Conduit
- A choice of either:
- An Endurance Conduit and Better Together, effectively working out to 40 permanent additional Mastery.
- A Finesse Conduit and Path of the Devoted, which is very weak considering that players generally do not get affected by full loss-of-control effects outside of core misplays in PvE.
- Newfound Resolve, working like the Lady Inerva Darkvein Mythic mechanic, and granting you 12% Strength and Stamina for 15 seconds if you succeed in its test. This can be problematic as the add can spawn behind you.
Thanks to the last trait and the "bonus" 40 Mastery on top of the Mastery provided by the 9.0 tree, Pelagos remains a very viable and competitive Soulbind going into 9.1.
Kleia
Kleia gains the following Conduits:
- An additional Potency Conduit
- A choice of either:
- An Endurance Conduit and 3% Critical Strike whenever you damage an enemy above 90% health.
- A Finesse Conduit and 10% damage reduction for you and your lowest-health ally, along with the heal and the debuff cleanse for them as well, whenever you use your Phial of Serenity.
- Light the Path modifies Valiant Strikes by making each stack grant 0.25% more Critical Strike. When the stacks convert into a heal, you and the affected party member gain 5% Critical Strike.
Kleia has gained quite a lot in terms of crit-buffing power. Still, it is not enough to topple the Kyrian king that is Pelagos.
Mikanikos
Forgelite Prime Mikanikos gains the following Conduits:
- An additional Potency Conduit
- A choice of either:
- An Endurance Conduit and Soulglow Spectrometer, granting you up to 5% damage to your target, stacking over 15s, and possibly changing targets between activations.
- A Finesse Conduit and Reactive Retrofitting, which works out two absorbs totaling 16% of your maximum Health at time of proc, one for physical damage, and one for magical damage, per 30 seconds.
- Effusive Anima Accelerator deals AoE damage around the target you used Shackle the Unworthy on, and reduces its cooldown by up to 20s. This is pretty potent, but not as impactful as it is for some of the other classes.
Overall, Mikanikos has been buffed and is possibly a play for the Unholy Death Knight, especially in AoE scenarios.
Venthyr
Nadjia
Nadjia the Mistblade gains the following Conduits:
- An additional Potency Conduit
- A choice of either:
- A Finesse Conduit and Sinful Preservation, granting you 50% of the value of all Healthstones and health potions you consume as an absorb. This has mad value for Mythic+.
- An Endurance Conduit and Nimble Steps, snaring enemies near you by 10% and turning into a 4s root when you drop below 35% health.
- Fatal Flaw, granting you 20% Critical Strike or Versatility after The Euphoria effect from Thrill Seeker ends for 10 seconds. Will pretty much always give us Critical Strike (as long as your stats are well-balanced). Unfortunately does not sync with any cooldown for pure single target. Does see a big jump in power for Mythic+ since you can trigger the effect more often.
With these changes, Nadjia will very likely dethrone Theotar as the default Soulbind overall, even on top-tier progression.
Theotar
Theotar the Mad Duke's last trait feels underwhelming and can vary in its provided buff. As a result, it is very difficult to gauge its relative strength, but it is otherwise weak and uncontrollable.
Draven
General Draven gains the following Conduits:
- An additional Potency Conduit
- A choice of either:
- A Finesse Conduit and Regenerative Stone Skin, converting 15% of all overhealing into a 6s heal-over-time effect.
- An Endurance Conduit and Intimidation Tactics, granting you cooldown reduction on Door of Shadows when you are low on health. This is completely pointless.
- Battlefield Presence, which is basically up to 3% damage increase. Important to note is that it is only 1% on pure single-target which is really quite bad.
Draven continues as the worst Venthyr Soulbind.
Night Fae
Niya
Niya gains the following Conduits:
- An additional Potency Conduit
- A choice of either:
- An Endurance Conduit and Called Shot, granting you movement speed when you land a critical strike.
- A Finesse Conduit and Survivor's Rally, working as a 20% heal over 10 seconds when you drop below 50%, once per minute. It is a nice defensive addition for us.
- Bonded Hearts, causing you to effectively heal up to 5 nearby friendly targets for 2% of their health every 15s. If you heal somebody from another Covenant — which is kind of difficult considering that 95% of the DPS are Night Fae these days — each stack of Grove Invigoration is amplified by 50%.
Overall, Niya is getting some nice additions. Her previous power is large enough to carry her into the top spot for Unholy Death Knights in 9.1.
Dreamweaver
We do not expect Dreamweaver to make it to live in his current state. Waking Dreams effectively works as a permanent 30% damage reduction. As such, we expect a major rework of this Soulbind's new traits likely coming within a few weeks.
Dreamweaver is unlikely to be a competitive Soulbind in 9.1.
Korayn
Korayn gains the following Conduits:
- A Potency Conduit
- A choice of either:
- An Endurance Conduit and Vorkai Ambush, effectively working as a 5% DR from any mob you interrupt for 5 seconds. This has good value with Blinding Sleet but is generally not great since we do not expect any adds to hit us an awful lot.
- A Finesse Conduit and Hunt's Exhilaration, giving you 3% Leech for 5s when you damage a new mob.
- Wild Hunt Strategem, allowing you to gain a small amount of execute
damage whenever you trigger First Strike and requiring you to have two
targets nearby to optimize:
- One high on health (to proc First Strike).
- One low on health (to convert the Wild Hunt Strategem into its 5% extra damage buff).
Overall this Soulbind is, frankly, weak. First Strike still carries it, but that is all it has going for it.
Necrolord
Plague Deviser Marileth
Plague Deviser Marileth gains the following Conduits:
- A Potency Conduit
- A choice of either:
- An Endurance Conduit and Viscous Trail, which feels like a PvP Conduit.
- A Finesse Conduit and Undulating Maneuvers, which is basically a reduced version of a Brewmaster Monk's Stagger. It works as an absorb and can proc off itself.
- Kevin's Oozeling, which is very unwieldy and very poorly-described by the tooltip. Think of it like a pet guardian that melees whatever you autoattacked last. Whenever somebody nearby takes real damage (i.e., not absorbed), they gain a small shield. You, meanwhile, get 6% extra damage to anything the oozeling touched while it was up. When it despawns, all the effects go away.
Plague Deviser Marileth is looking really strong in Patch 9.1 with the addition of Kevin's Oozeling. A 6% damage increase is no joke and the single-target output will probably be solid.
Emeni
Emeni gains the following Conduits:
- A Potency Conduit
- A choice of either:
- An Endurance Conduit and Sole Slough, granting allies 20% speed when you start moving. Potentially situationally good on fights where fast, specific movement matters.
- A Finesse Conduit and Resilient Stitching, working out to a 15% magic damage absorb per minute. This is weak and uninteresting, but still worth mentioning.
- Pustule Eruption, which forces you to cast Fleshcraft to deal some damage to nearby enemies every time you take damage and heal your friends for some as well.
The final trait does add a sizeable amount of damage. It does force you to channel Fleshcraft for 3 seconds but you can often find instances where this is not too bad.
Bonesmith Heirmir
Bonesmith Heirmir gains the following Conduits:
- A Potency Conduit
- A choice of either:
- An Endurance Conduit and Carver's Eye, granting you a large amount of Mastery for 5 seconds whenever you damage an enemy above 90% health, stacking 5 times. It is a lot of Mastery and it has a ton of value on fights with adds or in Mythic+.
- A Finesse Conduit and Waking Bone Breastplate, increasing your max HP by 5% whenever 3 or more enemies are nearby. This is simple and likely good in Mythic+, but weaker than Carver's Eye due to it having no offensive/throughput benefits.
- Mnemonic Equipment, working out to 3% more execute damage which is nice. Its overall output increase is not huge but still nice with more execute damage.
Heirmir synergises very well with the Unholy Death Knight and will be the best Soulbind overall in 9.1. Her Critical Strike buff aligns well with our Unholy Blight and Dark Transformation combo and the two new damage traits are really nice. There is a concern that the execute damage will not work on pets but that will hopefully be fixed.
