Decay

Decay is a uncommon-tier emitter-type quirk which allows the user to disintegrate whatever they touch with their hands. Whether the target is organic or not, it will always work. This quirk is held by Shigaraki Tomura in BHNA

Level 10-Decay: A grab move that inflicts the opponent with DoT (Damage over Time) |Cost:800|

Level 30-Decay Floor: You use decay on the floor around you and it also does DoT |Cost:1500|

Level 65-Decay Rush: Decay in a line in front of you |Cost:4000|

Usage
