Halberd 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.

Heavy: Creatures that are Small or Tiny have disadvantage on attack rolls with heavy weapons. A heavy weapon's size and bulk make it too large for a Small or Tiny creature to use effectively.

Reach: This weapon adds 5 feet to your reach when you attack with it, as well as when determining your reach for opportunity attacks with it.

Two-Handed: This weapon requires two hands when you attack with it.
