“	Reduces ASPD by 30 and causes subsequent applications of the Cold status during the debuff duration to inflict Frozen.	”
	—In-game tip

Cold is an Negative Status in Arknights.

Effect

A unit being inflicted with Cold is indicated by a "snowflake" effect above them. In this state, the unit will have their ASPD reduced by 30, which means that this is only relevant for those who can attack.

Unlike other Negative Statuses, should a unit being inflicted with Cold be hit by another instance of Cold, they will become Frozen instead of having the Cold effect refreshed.

Sources

• Units on Icy Surfaces will be inflicted with Cold.
• When a Snowfall occurs, all units will be inflicted with Cold.
