just a little addition... Ardendor [insert link here once there's a pedia page] does Void damage; Triggered Caliburn [insert link here once pedia is up] also does Void when triggered against:
It triggers against the following monsters: undead, vamps, demons, necromancers, zombies, dracopyres, "doom", and werewolves (categories were + wolf).
When triggered, it scales based on [Your Level], deals 120% damage, and deals Void damage. However, since the monster's Void resistance is (usually) 200%, the blade does half damage.
cyclone wyverns do purple damage I think
and basically a lot of stuff on here: poison guide should be mentioned because of the harm damage...
