Dragon Rend

You rip through the air with magically manifested dragon claws, evoking gales of wind to cut through foes. A creature in range must succeed on a Dexterity saving throw, taking slashing damage equal to 2d6 + your Strength modifier on a failed save.

If you are concentrating on claws of the dragon when you cast this spell, the target will take half of the damage rolled instead of none on a successful save.

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.
