Cinder's Chaotic Orb

When you cast this spell, you must take 1d8 + Spell Slot Lvl worth of damage or the spell immediately fails. You hurl a 4-inch-diameter sphere of energy at a creature that you can see within range. Choose one ability score, then choose acid, cold, fire, lightening, poison or thunder. The target must succeed on a saving throw using the chosen ability score; it takes 4d6 damage of the chosen type on a failed saving throw, or half as much om a successful one.
