Pacifying Blade

You brandish the weapon used in the casting of this spell and make a melee attack with it against one creature within the weapon's range. On a hit, the target suffers the weapon attack's normal effect and is surrounded by motes of radiant energy until the start of your next turn. If the target makes an attack before then, it takes 1d6 radiant damage.

This spell’s damage increases when you reach certain levels. At 5th level, the attack deals an extra 1d6 radiant damage to the target on a hit, and the damage the target takes if it attacks increases to 2d6. Both damage rolls increase by 1d6 at 11th level (2d6 and 3d6) and again at 17th level (3d6 and 4d6).
