Umbrella of the Sun and Moon

A creature in possession of both the Lunar Weapon and the Solar Amulet can perform a 1-hour ritual (as if attuning to a magic item) to combine those items, forming the Weapon of the Sun and Moon. In addition to having the properties of both the Lunar Weapon and the Solar Amulet, this weapon is considered a +1 Weapon and gains two Eclipse Powers. During the day, the Weapon of the Sun and Moon can use its Eclipse Power to cast the Darkness spell; this version of the spell creates a 60-foot-radius sphere of darkness, instead of its normal size. During the night, it can use its Eclipse Power to cast the Daylight spell. Once the daytime Eclipse Power is used, it can't be used again until the next dawn; once the nighttime Eclipse Power is used, it can't be used again until the next dusk.

Special: Whenever you take falling damage while wielding an umbrella, you can use your reaction to reduce the damage by a number equal to twice your proficiency bonus.

Finesse: When making an attack with a finesse weapon, you use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.
