GUIDEMechanics and How to Use

At a Glance

A single-target Envy Pierce E.G.O that applies Curse and triggers it twice immediately after attacking, earning debuffs without waiting for the single Turn End trigger.

Core Mechanics

  • Early Curse triggers: After the attack, if the target has Curse, its effect triggers twice immediately and Curse decreases by 2. Curse normally triggers only once at Turn End, giving a random debuff next turn (Attack or Defense Power Down, Offense or Defense Level Down).
  • Inflicting Curse and Nails: Inflicts 2 Curse and 2 Nails (3 at Threadspin Ⅲ) on hit. Additional Curse is added per 3 negative effects other than Curse and Nails (2 at Threadspin Ⅳ), up to 2. Nails is a special Bleed that inflicts Bleed at Turn Start.
  • Multi-target through Envy Resonance: Attack Weight is 1. +1 at 4 or more Envy Resonance (Threadspin Ⅲ), and at Threadspin Ⅳ, +1 per 3 Resonance (up to 2).
  • Clash Power Down: On hit against a target with 4 or more Curse, inflicts 1 Clash Power Down that turn (Threadspin Ⅳ, once per turn).
  • Passive — Grimy Hide: If he has a negative effect at Combat Start, he gains 1 Clash Power Up and 1 Defense Power Up. 1 Protection per 3 negative effects, up to 2.

How to Use

  • Stack Curse first, then use this E.G.O to trigger it early, layering debuffs for the next turn. The debuffs do not apply on the turn they trigger.
  • Its power is lowish (7 Base Power, 9 at Threadspin Ⅳ), so use it as a debuffer rather than a damage dealer.
  • It requires 2 Lust, 2 Pride, and 2 Envy, with a Sanity cost of 20 for Awakening and 25 for Corrosion.

SYNERGYTeams and Synergies

  • Zwei Assoc. West Section 3: Has skills that handle Tremor, likely meshing with Grimy Hide's negative effect condition. His Defense skill is a Clashable Guard that can use the Clash and Defense Power Up.
  • The Middle Little Brother: S2, S3, and his Defense skill are Envy, making it easy to build Envy Resonance and raise Attack Weight.
