While this character struggles being built from scratch, after the accumulation of some gear the Poison Necromancer becomes one of the strongest Heroes in the game capable of quickly tearing down most areas even on /players 8 in no time at all. This character also uses way less Skill Points than most characters, leaving a lot of room for options in what to add to the build.
