Make a list of the craziest (functional) characters you can think of. Myself, I once built a bowazon-slaying druid using lots of speed charms and a hellslayer in order to run faster than arrows.
I could still think of crazy things, such as a "Kamikazon", an Amazon with some extremely heavy gear for life, fire resistance in defense, built for the sole purpose of surviving a lot of explosions from a certain horde of suicide bombers in the later part of Act 5.
