Of course, we all know that in the tram, you can easily max your weapon skill. Did you know that you could max your defense skill as well?
Polymorph a rat, find another rat, polymorph that one, repeat until you have a good 5-7 attacking you.
Yeah it's easy, yeah it was probably posted before, but I've never seen a rat attacking someone before. I'm sure it will work with other classes, just find a way to piss them off (warlocks fear, etc etc).
