Truth's Justice

Radiant fire bursts from your body, healing your allies and burning your enemies. Each creature of your choice within range regains 12d10 + spellcasting modifier hit points and are also cured of all diseases.

All other creatures withing range must make a dexterity saving throw. Each creature takes 10d8 fire damage and 10d8 radiant damage on a failed save, or half as much damage on a successful one.

The healing portion of this spell does not affect undead or constructs.
