One of the basic abilties of the Damnifier, in my map caster units cost 3 food, have more life, mana, damage and 1 extra spell.

Dominate Death: puts an enemy undead unit of level 5 or below to sleep for 13 seconds, if it is not woken up after 13 seconds it will fall under your control. When used on allies it will deny one instance of fatal damage and will heal them for 111 points. Lasts for 90 seconds, only prevents one instance of fatal damage until the duration ends, can't be dispeled.
