Card Swarm

You teleport yourself to an unoccupied space you can see within range. Immediately after you disappear, you leave behind an explosive swarm of magical playing cards. Each creature within 5ft of your original position must make a DEX saving throw. On a failed save, the targets take 2d6 slashing damage, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot above 2nd.
