Ember Shower

You hold your hand up into the sky and summon a shower of embers down to the ground. Embers shower down at a 20 foot cylinder. Each creature in the area must succeed on a Dexterity saving throw. On a failed save, the creature takes 3d10 fire damage and is knocked prone. On a successful save, the creature takes half 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 1d10 for every slot level above 2nd.
