A multi-target Envy Slash E.G.O that cuts down enemies slower than her and heals when it staggers or defeats them.
Core Mechanics
Speed-difference bonus: +4 Coin Power (+7 at Threadspin Ⅳ) if the main target is at least 3 Speed slower than her. Little benefit against fast enemies.
Damage from Bind: On hit, +20% damage (40% at Threadspin Ⅳ) if the target has at least 3 Bind. Another source is needed to inflict 3 Bind.
Healing (Threadspin Ⅲ): Staggering or defeating a target with this skill heals the 1 ally with the lowest HP and herself by 10% of max HP.
Passive — Predator: If she healed more than 10% of her max HP that turn, she gains 1 Attack Power Up next turn.
Securing Envy: This is Ryōshū's only Envy E.G.O, so it also gives her a way to take part in Envy Resonance.
How to Use
Use it when there are several enemies she can outspeed, catching enemies at their Stagger Threshold to aim for the healing.
Treat the Bind condition as a bonus if it can be met by using Bind Identities first.
Applying 3 Bind with Red Eyes and then firing this costs two turns' worth of resources and SP, which is likely not worth it.
The Corrosion skill is a Minus Coin skill with a bigger damage increase than Awakening, but Awakening should be the main choice.
