Cob's Orb of Chance

You summon an orb in the shape of an icosahedron made of some type of energy. Make a ranged spell attack against a target you can see within 60 feet of you. On a hit, the target takes 8d8 damage, or half as much damage on a miss. The damage type is randomly determined by the roll of a d10. You or your DM can roll the die to determine the damage type. If you roll a 1 on the attack roll, the orb explodes in your hand, and you take the damage instead.

At Higher Levels: When you cast this spell with a spell slot of 5th level or higher, the damage increases by 1d8 for every level above 4th.
