Remember when karakuls used to do this?

[Felis]

Ya... those Dodos. Attack them in front, problem. Moved to their rear, more problems.

that was an NM (boss), not a regular mob.

Every Karakul had the sleep attack. At least I can remember that the Karakuls in the leves did it, before the NM came ingame.
