“	Reduces the target's ATK by the corresponding amount (only the strongest effect of this type applies).	”
	—In-game tip (unofficial translation)

Weaken is a debuff in Arknights, introduced alongside Lone Trail.

Overview[]

Only enemies can be inflicted with Weaken, which lowers their ATK by a designated amount. Multiple instances of Weaken do not stack, with the most effective taking precedence over the other(s). It is currently unknown whether Weaken stacks with other sources of ATK reduction.

Sources[]

All Hexer Supporters with the UMD-X Operator Module apply 10% Weaken for 2 seconds whenever attacking an enemy.
