Quest: Lunk's Adventure: Cranky Little Dwarfs

[Zexis-dathremar]

The foam sword effect reduces the mobs health, but Lunk does not jump on the target and any other weapon or unarmed attack kills the mob instantly.

This was reported incorrectly in January here:

Lunk’s adventure: Cranky little dwarfs bugged

Lunk will not jump on the dwarfs no matter how weak they are and he vanishes randomly. I abandon the quest and pick it back up same thing over and over can’t finish it. Don’t know what to do.
