GUIDEMechanics and How to Use

At a Glance

A multi-target Pride Slash E.G.O whose damage soars the more Poise she builds before using it; its Corrosion skill benefits from killing allies.

Core Mechanics

Replacement bonuses from Poise: Before attacking, she gains Poise and Poise Count, but at 15 or more Poise, Final Power rises instead of Poise, and at 5 or more Poise Count, Coin Power rises instead of Count (Final Power scales with the highest Resonance, and the Count side with half of it).
Critical bonus: Coin Ⅱ gains Critical damage based on combined Poise Potency and Count, up to 20% at Threadspin Ⅲ and 40% at Ⅳ. It also grants Deep Inhale on hit.
On kills: Defeating a target grants Deep Inhale next turn. Deep Inhale spends Poise Potency on Critical Hits to add Critical damage.
Corrosion skill: Attacks the target with the lowest HP, prioritizing allies. +30% damage if allies are included, and from Threadspin Ⅲ, killing an ally restores SP.
Passive — Breath: At the start of the turn after use, she gains 1 Nebulizer β, plus 1 for each enemy defeated and 2 for each ally defeated (accumulates during battle, up to 5). At Combat Start on a turn with Pride Absolute Resonance, she and a random ally gain Poise and Poise Count.

How to Use

Fire it at multiple enemies once Poise has built up. Turn 2 or later is likely a good guideline.
The more Resonance you build, the more easily the bonuses reach their maximum.
The Corrosion skill spends her own HP to make up Poise when it is below 15. Because it kills allies, handle it with care outside specific teams.
It requires 1 Wrath, 1 Lust, and 5 Pride, heavily skewed toward Pride.

ANALYSISThreadspin

Ⅱ: Unlocks Breath.
Ⅲ: The Resonance-based cap becomes 6, and the Critical damage increase and the Corrosion skill's Poise infliction are added.
Ⅳ: Raises Base Power, raises the Count-based bonus cap to 3, and raises the Critical damage increase to up to 40%. The Corrosion skill gains an effect that returns resources.
