Lich

"A master of the undead who resurrects dead enemies as obedient skeletons to fight for him"

The Lich is an expensive, low Hit Point unit. When it is on the battlefield, each time an enemy dies, it resurrects it as a skeleton, which fights for the Lich. Resurrected skeletons each have 2 hit points. The Lich is unique for Mortis and can be only used by her.

Trivia

 * The resurrected skeleton is stat-wise very similar to a Beast.
