Sleep

Sleep is a control debuff that renders the afflicted unit completely unable to act until it is damaged. A sleeping unit skips its turns indefinitely until an attack wakes it up, making Sleep one of the longest-lasting disables in the game if left unchecked.

The counterplay to Sleep is straightforward: any damage breaks it. This means Sleep is less effective against units with damage-over-time effects already ticking, since the DoT will wake them immediately. Strategically, Sleep can be used offensively to disable a dangerous enemy while you deal with other threats, then wake it on your terms. The Drowsy status often precedes Sleep, giving a one-turn warning before the full disable kicks in.
