Ephemeral Edge

You wrap yourself in ephemeral energy, giving you extra damage to your attacks until the beginning of your next turn. On a hit, the target suffers the weapon attack’s normal effects and takes an additional 1d6 psychic damage. 

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
