Winter Rose’s Bloom

Once cast, a large winter rose grows around you before erupting into shards of ice, scattering around you rapidly. The burst of ice and thorns launch at each creature in a 10ft radius originating from you, and they must make a dexterity saving throw. On a failed save, a creature takes 4d6 cold damage and is knocked prone. On a successful save, the creature takes half as much damage and isn’t knocked prone.

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 level above the 2nd.
