“	Absorbs a certain amount of damage.	”
	—In-game tip

Barrier is a buff in Arknights, introduced in Il Siracusano.

Effect

Only friendly units can receive Barrier, which absorbs a certain amount of damage taken by the bearer before being expended.

The Barrier's strength is represented by a brighter part on the unit's HP meter, which divides their own HP and the Barrier's HP.

	Wreathed in Thorns	If Penance has a Barrier from her skills or Guardian of the Law, enemies that attacked her will receive Arts damage equal to 50% (+3% P5) of Penance's ATK.

Trivia

• Because the HP loss from Warfarin's Unstable Plasma is counted as direct HP removal, it will not be absorbed by the Barrier.
