Sword of Theton

You create a magical sword in your open hand. This sword functions as a broadsword. You must use your action this turn to attack with that weapon, or else the spell fails. The weapon deals 4d10 force damage on a hit and acts as though it has the wounding property. This deals damage to all types of creatures, and overcomes, resistances, immunities, and damage reduction. 

For each level after the 4th, the spell's damage increases by 2d10.
