Arms of the Kraken

You invoke the power of The Kraken. Large tentacles erupt from you and batter all creatures within 10 feet of you. Each creature in that area must make a Strength saving throw. On a failed save, a target takes 2d6 Bludgeoning damage. On a successful save, the creature takes half damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
