Elemental Ball

You summon a 1 foot sphere of a random element, and it flies toward a target within range. 

Roll a d6 for the element. 1 is Fire, 2 is Radiant, 3 is Necrotic, 4 is Acid, 5 is Lightning, and 6 is Thunder.

The target must succeed a dexterity saving throw, or take 2d10 of your random damage type. The DC is your spell save DC.

You can cast this using higher level slots. For each slot above first, this spell deals 1d10 more damage.
