Demonology Warlock: Midnight Expansion Preview

Welcome to our Midnight expansion preview for Demonology Warlock, a resource page where you can find changes, Hero talent trees, and an initial assessment on the state of the spec.

The purpose of this page is to offer an up-to-date overview of how Demonology Warlock is changing in the forthcoming Midnight expansion. As such, it is not to be treated as a guide or a replacement, since the current state of tuning is not representative of what the final product will be.

Midnight Changes for Demonology Warlock

2.1.

Core Changes

Demonology Warlock received a complete talent restructuring for the class and the specialisation trees alongside a fourth branch for each Hero Tree.

Below are the most notable changes:

  • Curses are now mutually exclusive choices, meaning players will have to choose between Curse of Weakness Icon Curse of Weakness, Curse of Tongues Icon Curse of Tongues and Curse of Exhaustion Icon Curse of Exhaustion;
  • A new talent Foul Mouth Icon Foul Mouth allows chosen curses to also affect any secondary target within 10 yards of the main target;
  • Howl of Terror Icon Howl of Terror is on a choice node with Shadowfury Icon Shadowfury;
  • Demonic Gateway Icon Demonic Gateway has been moved further down the tree and has a supporting talent that allows players to use it twice before incurring the cooldown;
  • Blight of Weakness Icon Blight of Weakness is a new AoE debuff effect that is mutually exclusive with any Curses.

Going into Midnight, the intention seems to offer the AoE Curses at the expense of less flexibility in what to choose from the start. That creates a situation where the default choice will most likely be Curse of Tongues Icon Curse of Tongues , as the alternatives do not offer enough of an upside in a direct comparison, barred some very specific cases. Warlock's overall utility package seems to be still on the lower end of the spectrum, especially in Mythic+ scenarios. Howl of Terror Icon Howl of Terror has the potential to be used as a more reliable interrupt, but the target cap is still a bit of a problem.

Moving on to the Demonology side, the whole tree has been overhauled to lessen the reliance on addons and the need to track multiple effects. The layout is for the most part similar, progressing from a first gate almost devoid of choices towards the third gate which holds most of the options comparatively.

See below a list of the most transformative changes:

  • Wild Imps behaviour has changed and they will last 40 seconds without any energy consumption associated and start with a cap of 3;
  • Imp Mastery Icon Imp Mastery and Hellbent Commander Icon Hellbent Commander raise the cap by 3 each, for a maximum of 9 when taking both;
  • Hand of Gul'dan Icon Hand of Gul'dan has been changed to a modal spender, AoE until reaching the maximum number of Wild Imps available and then single target as long as the threshold is met;
  • Demonic Strength Icon Demonic Strength and Bilescourge Bombers Icon Bilescourge Bombers have been removed;
  • Soul Strike Icon Soul Strike has been removed;
  • Grimoire: Felguard Icon Grimoire: Felguard has been removed;
  • Doom Icon Doom has been removed;
  • Vile Fiend Icon Vile Fiend and its upgrade in Mark of Shatug Icon Mark of Shatug or Mark of F'harg Icon Mark of F'harg have been appended to Call Dreadstalkers Icon Call Dreadstalkers and cannot be casted on their own;
  • The new Apex talent Dominion of Argus Icon Dominion of Argus is themed around summoning a third Dreadstalker, doubling the damage of Felguard abilities, and a random Soulkeeper summon.

Midnight Demonology tree has been streamlined and simplified to a great extent, with thematic areas consolidated around the themes of Wild Imps, Felguard, and Dreadstalkers. Most effects/extra abilities have been integrated into the baseline rotational skills.

Developers’ notes: Our first goal for Demonology as we move into Midnight is to address Demonology’s reliance on addons to monitor Wild Imp energy to make decisions on when to cast spells like Implosion, Power Siphon, and Summon Demonic Tyrant. To accomplish this, we are removing the energy component from Wild Imps which means that Wild Imps will be around much longer (40 seconds) before disappearing. In efforts to prevent many Wild Imps from running around, we are adding a limit to how many Wild Imps you can have summoned at once that can be increased via multiple talents. Secondly, we want to take a hard look at Demonology’s ramp time and make adjustments to the number of casts or cooldowns needed to execute high throughput.

While the gameplay idea remains mostly the same in practical terms most of the rotation has been simplified, Tyrant setups have been removed, alongside most short cooldowns.

Hand of Gul'dan Icon Hand of Gul'dan's' new behaviour offers a straightforward approach to Implosion Icon Implosion cycles but equally limits the choice in when to use single target and when to AoE.

Hero Talent Trees for Demonology Warlock in Midnight

Hero Trees have not been updated yet, with only the description of the fourth column being available.

3.1.

Diabolist Hero Talents for Demonology Warlock

The Diabolist Hero tree is themed around a sequence of Greater Demons that offer temporary effects such as damage amplification, shard generation or a high damage AoE ability before cycling toward the next one.

The playstyle, as such, is influenced by this cadence while not being an interference in the rotation at the same time. What changes the most is the damage profile instead, with Gloom of Nathreza Icon Gloom of Nathreza directly buffing shard spenders, and higher burst capabilities thanks to Ruination Icon Ruination or particularly in Tyrant windows, thanks to Abyssal Dominion Icon Abyssal Dominion.

Regarding defensive options and utility, Soul-Etched Circles Icon Soul-Etched Circles offers a niche use case while Annihilan's Bellow Icon Annihilan's Bellow drastically increases the frequency of use of Howl of Terror Icon Howl of Terror. Infernal Vitality Icon Infernal Vitality and Infernal Bulwark Icon Infernal Bulwark also ties a sustain element to Unending Resolve Icon Unending Resolve which is definitely more enticing than what other Hero Tree currently seem to offer, albeit overall not great.

3.2.

Soul Harvester Hero Talents for Demonology Warlock

The Soul Harvester Hero tree takes a different approach, with a theme centered around shard cost reduction for spenders, direct damage increase, and additional damage over time in the form of Soul Anathema Icon Soul Anathema.

The synergy with Power Siphon Icon Power Siphon through Necrolyte Teachings Icon Necrolyte Teachings and Sataiel's Ambition Icon Sataiel's Ambition while not being as transformative as it is in Affliction still offers a reliable direct damage increase, particularly with Shadow Bolt Icon Shadow Bolt when talenting Rune of Shadows Icon Rune of Shadows and Sacrificed Souls Icon Sacrificed Souls.

In AoE Mantle of the Harvester Icon Mantle of the Harvester helps provide additional Demonic Core Icon Demonic Core to fuel the damage.

In terms of defensive and utility options, again few improvements in terms of Gorebound Fortitude Icon Gorebound Fortitude offering Soulburn Icon Soulburn Healthstone Icon Healthstones at no additional shard cost, and Friends In Dark Places Icon Friends In Dark Places giving an additional 25% to the baseline absorb value of Dark Pact Icon Dark Pact. Eternal Servitude Icon Eternal Servitude on the other hand enable a more frequent pet swapping/resummoning as a quality-of-life change, with the alternative of an improved combat res in Gorefiend's Resolve Icon Gorefiend's Resolve similar to other classes.
