Auril's Flowers

the Queen of Air and Darkness gave you access to one of her trademark spells.

Choose a point you can see on the ground within range. Moisture and water condense under the ground and blooms into an exploding mound of churned ice in a 30-foot sphere centered in that point. Each creature in that area must make a Dexterity saving throw. A creature takes 8d10 cold damage. The area then become difficult terrain until cleared. Each 5-foot-square portion takes 2 minutes to clear by hand.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 8d10 for each slot level above 6th.
