It's not clear other than that it seems redundent with [Paralysis]. It's probably a level draining spell, though it would seem redundant with his negative energy touch. However, he probably had to disable that skill to avoid killing them accidentally.

The collar is apparently an item that increases XP gain in exchange for some penalties. It's the same thing the Lizardmen were wearing while they trained.
