Warding Light Weapon

You may spend 1 Action to touch a weapon within range and engulf it in a blinding sphere of light. For the next 10 minutes, the chosen weapon does an extra 1d6 radiant damage and glows with bright light for 40 feet and dim light for 80. If the weapon is used to make an attack against undead or fiend, the light burns it on contact, dealing another 1d4 fire damage.
