Hydaelyn

You create a circle of corrupted earth on the ground centered on a point around you. This area, with a radius of 10 feet, is difficult terrain for all creatures except you, dealing 2d4 necrotic damage for every 5 feet they travel within it. When Doton appears, all creatures within the ring must make a Dexterity saving throw, taking 4d4 necrotic damage on a failed save, or half as much on a successful one. You are unaffected by this damage. When you cast this spell using a spell slot of 4th level or higher, the damage 2d4 necrotic for each slot level above 3rd. This applies to damage when first casted and damage in later turns.
