Berserker

"This duel-wielding sword fighter attacks faster when he is below 4 hit points"

The Berserker is a moderate Hit Point melee unit that costs 5 mana to deploy. Once its Hit Points go below four, it starts attacking roughly twice as fast. This effect is similar to the effect of a Rage spell. The Berserker can be used by Mortis, Scraps and Jinni.
