Attack Slow

Attack Slow is a debuff that decreases a units Attack Speed. There is currently no visual indicator for Attack Speed debuffs, and a change in Attack Speed can only be seen by opening the unit's Target Info Panel. Attack Slow debuff can be removed by Invulnerable and most Stasis effects, but not by Unstoppable.

Attack Slows stack additively with all effects that can affect the target Hero's Attack Speed, but a Hero's total Attack Speed cannot be reduced below 25% of their base Attack Speed.
