Chaos Bomb

You channel the powers of limbo and target a point within 100 ft of you. A 10ft radius there explodes with chaotic magic, making any creature in the radius make a Dexterity saving throw or take 1d12 lightning, 1d12 acid, 1d12 fire, and 1d12 cold and fall prone. If they succeed they take 1d12 fire, lightning, acid, or cold, and another 1d12 of a different damage type on the list. They do not fall prone
