Warding Focus

You extend your hand and trace a sigil of warding in the air. The attacker must make a Dexterity saving throw against your spellcasting DC. If they fail, roll 1d10 and subtract that number from the damage done to you, granted it was slashing, piercing, or bludgeoning. If they succeed, they do the normal amount of damage.

The damage ward increases, 2d10 at 5th level, 3d10 at 11th, and 4d10 at 17th.
