Vigor

“	When HP is higher than a certain percentage, increases ATK by the effect percentage (only the highest ATK increase from effects of this type will be applied).	”
	—In-game tip

Vigor is a buff in Arknights.

Overview

Vigor increases ATK by a percentage so long as the target's HP is above a specific percentage (not amount). Multiple instances of Vigor are mutually exclusive on a unit; the highest effect takes precedence over the others.
