Guide🔗

The following is subjective community opinion from NamuWiki (KR server).

Performance: Base class is Witch. Tier 3 classes are Lich / Hellinvoker / Nightmare. Ultimate is "Trinity Destroyer," unique weapon "Lord of the Moon." Unique passive "Harsh Night's Mission": applying a debuff grants a spell-power-scaling defense/resistance buff, stackable up to 8; casting an action-control skill raises spell power for 1 turn; when the action-control effect you applied expires, it picks 1 of the opponent's skills and puts it on cooldown as if used. Buff values scale with awakening level, and cooled-down skills increase up to 2.

Unique skills are Phantom Walk (learned by Nightmare) and Exort Spirit (learned by Hellinvoker). Phantom Walk is regarded as Diablo's core AoE skill: move to a designated tile within 3 tiles, deal 40% of spell power to enemies within 2 tiles, apply "Confusion" (random flee within movable range), then apply Banish for 1 turn to enemies within 2 tiles. Considered one of the strongest formation-breaking techniques in the game: once Diablo dives in with Phantom Walk, enemies scatter, and any that remain near Diablo get Banished and can do nothing for 1 turn. Also attractive as a teleport for simple movement or crisis escape.

Exort Spirit is a single-target skill: 40% spell-power damage, then Banish target for 1 turn. Whether the target dies or is banished, a "Corrupted Spirit" is summoned nearby, having half the target's stats and the same active skills. Rated as awkward/mediocre because when the target returns from Banish it dies instantly, cannot use its ultimate, and has halved stats, making it hard to use.

Mind Control (learned by Lich) is also fairly important. Previously it was risky and mostly used in dungeons etc., but since the Black Prince's arrival in Jan 2025 it has been re-evaluated as a Black-Prince counter skill; mind-controlling the enemy Black Prince to slam Asura Pacheonmu into the enemy's own formation is a sight to behold.

Trinity Destroyer (ultimate) designates 1 tile within 3 tiles and casts 3 dark spells at once: within 2 tiles 25% damage + "Despair" (cannot gain removable buffs, 2 turns); within 3 tiles 35% + random debuff; within 4 tiles 45% damage. Closer to the cast point = stronger hit and debuff. Power is a bit low but compensated by debuffs; however Diablo is usually too busy using Phantom Walk and Silent Cloud, so situations to use it rarely arise.

Recommended gear: The unique weapon Lord of the Moon gives spell power as an extra stat and has a weapon skill applying "Soul Burst" when an action-control effect on an enemy is removed; Soul Burst deals spell-power-scaling damage on expiry, and with weapon awakening both power and range grow 1, so from 4-awaken it becomes nearly an AoE. High-awaken unique weapon is thus recommended. Armor: Dark Mage set at hero grade; at legendary grade the Pope set (modeled on Rubens Heisenberg's papal attire) is recommended. Since she is usually paired with Gishne, you must match a 3-TP-per-turn cycle, and because Phantom Walk is the mainstay, securing tanking is also important. Accessories: Black Dice for tanking, or a Stopwatch to secure spell power and cooldown.

Evaluation: A debuffer specialized in action control. Can wield strong AoE status magic like Silent Cloud plus action control such as Mind Control and Exort Spirit; Phantom Walk combines both and is Diablo's crown jewel. Can also command summons. Picking the Nightmare class keeps debuffs going to continuously harass enemies; the unique weapon deals spell-power-scaling extra damage when an action-control debuff is removed, and at high awaken the damage range grows so that at 6-awaken it reaches 2 tiles around, turning each enemy into a "human bomb." Combined with Gishne, TP-3 skills can be spammed every turn, and a formation-collapse party using these two was once popular. To run it, 3 TP must be spent each turn, so the standard is to unify all Diablo's skills to TP 3 or 1 (TP 1 naturally recovers next turn). Usually Phantom Walk plus AoE-silence Silent Cloud, then one of Mind Control / Death Rise (sword-shield summon) / Dark Blast (single dark attack that also debuffs). However, as power inflation continued and debuff counters kept appearing, stability dropped and she has fallen out of the first tier. (No explicit S/A/B tier letter is stated.)

Awakening/Manifestation progression: Awakening tiers appear on the unique passive "Harsh Night's Mission" and on the ultimate "Trinity Destroyer." Listed stages: First Acquisition, Max Awakening, Max Manifestation. Unique Passive - Harsh Night's Mission: - First Acquisition: After applying a debuff to an enemy with a skill, defense and resistance increase by 2% of spell power (max 8 stacks). When casting an action-control skill, spell power increases by 15% for 1 turn. When an action-control effect you applied expires, it puts 1 of the target's skills on cooldown as if it had been used (unused skills take priority). - Max Awakening: defense/resistance +5% of spell power (max 8 stacks); action-control cast: spell power +40% for 1 turn; on expiry puts 2 of the target's skills on cooldown (unused skills prioritized). - Max Manifestation: Max HP +20%. After applying a debuff, defense/resistance +6% of spell power (2 stacks per debuff, max 8 stacks); action-control cast: spell power +60% for 1 turn; on expiry puts 2 of the target's skills on cooldown (unused skills prioritized). Ultimate - Trinity Destroyer (designate a tile within 3 tiles, triggers 3 dark spells at once): - First Acquisition: enemies within 2 tiles take 20% of spell power damage + "Despair" for 2 turns; enemies within 3 tiles take 30% + random debuff; enemies within 4 tiles take 40%. - Max Awakening: 35% (2 tiles, +Despair 2 turns) / 45% (3 tiles, +random debuff) / 55% (4 tiles). - Max Manifestation: 50% (2 tiles, +Despair 2 turns) / 60% (3 tiles, +random debuff) / 70% (4 tiles). - Despair Cannot be removedSkill control (lasts 2): cannot gain removable buffs.
