On my Wizzy, I was trying to move him to the water and this Veno comes along and keeps killin' it with their pet, so I just quietly followed them around for a while, and they keep askin' "why are you following me?" after 5 minutes of this they must have gotten creeped out and they left the area...
I wait for the respawn and I start the whole chase him around thing smacking him with by wand, at one point I need to avoid spiders and I go back to spawn point and wait for his return, here's where it gets weird... I start hittin' him again and he just stands there, it took under 2 minutes to do him in.
