Cedar's Winged Gambit

You task 4 cards/leaves/feathers and fling them at up to four creatures within range. The projectiles are engulfed in a magical flame with the user's chosen color(s). Make a ranged spell attack against the target. On a hit, the target takes 1d10 force damage. Hit or miss, the shard then explodes. The target and each creature within 5 feet of it must succeed on a Dexterity saving throw or take 2d6 fire damage.

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