Abilities: Undead. Flyer. Incorporeal. Mana drain.
This creature is insusceptible to morale, poisoning, blinding or mind-affecting effects. Life cannot be drained from it.
The creature can move around the battlefield ignoring obstacles (flying over them).
Physical attacks against this creature are only 50% likely to be successful. After two consecutive misses, third physical attack will hit, and vice versa. Any chaos spell successfully cast on this creature resets the counter.
This creature drains mana from its caster targets, and uses it to restore its health and even to raise perished units. 1 mana per attacking creature is drained, but no more than the caster stack possesses. Every 1 mana restores or raises 1 creature.
