Slow

Slow, also known as Stop, is a debuff in Arknights.

Effect

“	-80% Movement Speed.	”
	—In-game tip

Only enemy units can be inflicted with Slow, which is indicated by a minuscule blue electrical effect on them. In this state, the enemy will have their movement speed reduced by 80%, almost halting their movement which can be noticed on enemies with low MSPD.

Slow cannot be stacked, but MSPD reduction effects (e.g. Manticore's Scorpion Venom, Nightmare's Night Phantom) will stack with it, which can be used to further restrict the enemy's movement.

So far only stationary/large enemies and Nethersea/Nourished/Regressed Swarmcallers are immune to Slow, with the Regressed Swarmcaller in particular able to pass its Slow immunity to The Endspeaker, Will of We Many on its next form if it Consumes the Swarmcaller's Tombstone it leaves behind upon defeat.
