Dark ritual

This hero can only heal by retiring to their tomb once per level. Nearby pets are sacrificed to cast a death spell. 3 pets unlock full power!
After the sacrifice new level-based pets are summoned.
After casting the first dark ritual of the level the hero has access to a modified version.
Pets are sacrificed but instead of a death spell the hero is healed by their total health.
