GUIDEMechanics and How to Use

At a Glance

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.
