Corpse Bomb

When you cast this spell, blacken marks envelop the body for a short time before disappearing into the flesh, leaving a strange mark upon the chest, and setting a very dangerous event to occur when someone triggers. When the spell is triggered, the magic expands the flesh, tearing it apart, and sending the pieces flying through the air in a 10ft radius. Each creature from the center of this point must make a Dexterity Saving Throw. Target takes 10d6 necrotic damage on a failed save and half as much damage on a successful one.

The body becomes unrecognizable and any equipment upon the body destroyed when the spell is triggered.

Using a Corpse: When using a dead creature, you can set the conditions for the trigger such as; someone touching the body or when light touches it. The spell can be spotted with an Investigation check (Intelligence) against your spell DC.

Using on a Living Creature: When using on a living creature, they become a time bomb as the only trigger to be set is their death. Upon a willing creature, they sacrifice their Death Saves and will explode upon hitting 0 hp. Upon an unwilling creature, they must succeed a Wisdom Saving Throw or suffer the same fate. At the start of their turn, they can make another Saving Throw to try and fight the spell.

At Higher Levels. When casting this spell at 6th level or higher, the spells damage increases by 1d6 for every spell level above 5th.
