Electric Surge

If a creature touches you, hits you with a melee attack using a metal object, or hits you with any attack that uses a part of their body (such as an unarmed strike, natural weapon attack, etc) you can use your reaction to jolt them with electricity. The creature must make a Constitution Saving throw, taking 2d10 lightning damage on a failed save or half as much on a success.

At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 2d10 for each slot level above 1st.
