Compost

2nd-level necromancy

Casting Time:1 action
Range:Touch
Components:V, S, F
Duration:Instantaneous

When you cast this spell, you touch a corpse, accelerating its decay and reducing it to a fine dust.

The corpse can then no longer be magically animated or otherwise become undead. Thus, such spells as animate dead and raise dead have no effect upon a corpse affected by this spell. Compost does not interfere with resurrection.

The spell has no effect on living matter. If the spell is cast upon an undead creature, the target must make a Constitution saving throw, suffering 5d6 radiant damage on a failed saving throw, or half as much on a success. If the spell inflicts enough damage to reduce the undead to 0 hit points, the corpse turns to a fine dust and can no longer be animated or raised again.
