Desecrate

The caster creates a 100ft radius sphere around themselves in which the spell's effect is active. Whenever an undead creature is killed in the area of effect, they regain 1d4 hit points every round at the end of the creature's turn until they have reached their hit point maximum or they have left the area of effect.

This spell only ends if a Hallow spell cast at an equal or higher level is targeted at an area within the radius of the spell. The effect of the Hallow spell is destroyed whether it succeeds or fails in dispelling the desecrate effect. This spell can also be used in the same way to dispel Hallow spell effects. The same rules apply.

The gemstone used in the casting of this spell is not consumed by the spell.
