Blessings of The Monocled Duck

Channel Divinity PHB, pg. 86
Sacred Weapon - As an action you can imbue a
weapon with positive energy. For 1 minute, the
weapon is considered magical, you add +4 to
attack rolls, it emits bright light for 20 ft. and
dim light for 20 ft beyond that. You can end
the effect as part of any other action, if you are
no longer holding the weapon, or if you fall
unconscious. Channel Divinity: 1 Action {x}{ut}
