Not really an exploit, but Using a Bow Class You can kill undead skeletons without dying. It needs to be done in areas with some room to run around. Simply attack the Skeletons and run backwards, You'll barely get hit because their slow as hell. This could be an idea for a macro, it would be simple as hell. Only downside is the cost of Arrows.

Level Spots:
LVL 11-13: Skeletons Outside of Wailing Caves

As a wizzy/warlock, this is also doable. SImply 'pull' with your FULLY UPGRADED (ie: The BEST you can afford - yes, several gold is reasonable for the Adept III) Frozen Manacles, then load up every DoT you can cast, re-manacle, DD, DD, and if it's not dead yet just keep repeating. This works best on Yellow solos and under, although if you can find some single groups that are green^^ you can usually take those, but it's a gamble whether they will break the snare.
