Bolstering Strike

You brandish the weapon used in the spell’s casting and make a weapon attack with it against one creature within 30 feet of you. On a hit, the target suffers the weapon attack’s normal effects and you gain a number of temporary hit points equal to your spell casting ability modifier until the start of your next turn.

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d4 Radiant damage, and the temporary hp increase by amount of radiant damage done. the radiant damage rolls increase by 1d4 at 11th level (2d4) and 17th level (3d4).
