4th-level Spell: Necrotic Mine

Whispering (Necromancy)

You infuse explosive power into a skull, setting a supernatural trap that explodes with deathly energy when triggered. You can set this item to detonate when a living creature comes within 5, 10, or 15 feet of it.

When the skull explodes, each creature in a 20-foot radius must make a Dexterity saving throw. On a failure, a creature takes 6d8 necrotic damage and can't receive any healing until the end of its next turn. On a success, a creature suffers half as much damage and suffers no other effects. If a creature is affected by multiple necrotic mines in a turn, it takes half damage from any mines beyond the first on a failed save. If a creature is killed by a necrotic mine, it rises as a zombie on the next moonless night.

A supernatural mine must be set 5 feet or more from another mine, and cannot be moved once placed; any attempt to move it results in it detonating unless the original caster disarms it as an action.
