Alchemic Infliction Sphere

In one hand the caster summons a purple bluish hued ball of alchemic energy that grows to 3x3ft for a second then shrinks down to an inch. It stays hovering a foot above the casters sky facing palm, darting around in an erratic random patters only goes a max of 6 inch away from its idle position. The Warping Sphere can remain in your hand for any duration of time. As apart of the same action you may throw it by throwing your casting hand forward (all fingers out and together wit thumb erecting perpendicular to the fingers) toward your single target. The sphere flies off in a spiraling trajectory, forcing the air around it to disperse by its arcane force. The sphere gets bigger as it flashing through the sky until it grows to 3x3 feet. The target must succeed a DEX saving throw of the casters wisdom plus spell casting mod. in a 2x2 square landing area each who fail their DEX take 2d8 - DEX force damage and 2d6 + WIS magical damage. The burst of alchemic force tears through the space around it, burning the flesh of the enemy with its once healing properties. Your magical ability to trans mutate has turned this once healing potion into a force of castigation through pain. The enemies wont know what hit them, happy casting.
