Cosmic Pulse

You target one creature within range enshrouding it in spinning stardust. The targeted creature must make a Dexterity saving throw. On a failed save, a creature takes 4d8 force damage and is stunned until the end of their next turn. On a successful save, a creature takes half as much damage and isn’t stunned. When targeting a creature that is larger then size medium, they take 1d6 additional force damage per size above medium. All loose material within 5 feet of the target is pulled towards the target as the stardust implodes. 

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