School of Soul Magic. Casting this spell requires expending a number of Soul Shards equal to the level of the spell. Any character without Soul Shards who attempts to cast this spell immediately drops to 0 Hit Points after casting it and begins making Death Saving Throws. Their Hit Points can only be increased once they have stabilized and can only be stabilized by succeeding on three Death Saving Throws. If they die while in this state, they cannot be revived by any means short of a Wish spell.

You make a melee spell attack against a target within 5 feet as your souls battle for supremacy. On a hit, the target takes 8d12 Necrotic damage and you take 3d12 Radiant damage. On a miss, you take 8d12 Necrotic damage and the target takes 3d12 Radiant damage.

If this reduces the target to 0 Hit Points, you take no damage and instead regain Hit Points equal to half the damage dealt to the target.

Using a Higher-Level Spell Slot. The Necrotic damage increases by 1d12 and Radiant damage decreases by 1d12 (minimum of 1d12) for each spell slot level above 5.

This spell is intended for use with the Soulbreaker Wizard Homebrew Subclass.
