Aura of Retribution

Your body starts to radiate small amounts of radiation in a 30 foot radius. Until the spell ends, the aura moves with you, centered on you. Any creature(s) that attacks you or your allies within the aura immediately takes 1d8 radiant damage the first time it attacks.

After the first attack, the creature(s) must make an INT save throw every time it attacks.

On fail, it continues to take 1d8 damage. On a save, it takes half the damage.

At Higher Levels: At 8th level add an extra 1d8 damage. At 16th level add an extra 1d8 damage.
