Lich

The Lich is a magic casting hero. Therefore you should keep him as far away from melee encounters as possible. His main use is for hit-and-run tactics. Once he gets to level 6, he can learn death and decay. This attack lasts 35 seconds and drains all targets in the affect area of 4% of their hitpoints every second. Be careful though because if the Lich is moved while casting this spell, it stops! That means if you do not have a squad protecting the Lich, this could be a big waste of mana. Also, you cannot keep casting this spell over and over due to it being the Lich's "Ultimate Skill". You must wait a considerable amount of time before you can use this skill again. Out of the three Undead heroes, the Lich is the one I would least recommend!
