Corrosion skill: A Minus Coin with 24 Base Power and −10 Coin Power that triggers Tremor Burst on hit (Tremor Count decreases by 2). On Critical Hit or Tails Hit, it triggers an additional Tremor Burst. On Critical Hit, it also inflicts Bleed.
Passive — Fallen Stone Pagoda: Defeating an enemy with Bleed grants 2 Poise and 2 Poise Count, up to 3 times per turn. It works when you are defeating enemies one after another.
How to Use
It has no standout effect, so use it to cover what is missing in a team built around Bleed, Tremor, or Poise.
It pairs well with Identities that want Bleed Count added immediately.
Its Clash Power is 18–27, likely lacking punch as a low-cost Clash option.
It requires 2 Wrath, 2 Sloth, and 1 Pride, with an Awakening Sanity cost of 20.
