Light Repeating Crossbow of the Sun and Moon

Ammo: crossbow bolt

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.

This crossbow is fitted with a cartridge that can hold up to six crossbow bolts. It automatically reloads after firing until the cartridge runs out of ammunition. Reloading the cartridge takes an action.

Ammunition: You can use a weapon that has the ammunition property to make a ranged attack only if you have ammunition to fire from the weapon. Each time you attack with the weapon, you expend one piece of ammunition. The ammunition of a firearm is destroyed upon use. Drawing the ammunition from a quiver, case, or other container is part of the attack (you need a free hand to load a one-handed weapon). At the end of the battle, you can recover half your expended ammunition by taking a minute to search the battlefield. If you use a weapon that has the ammunition property to make a melee attack, you treat the weapon as an improvised weapon (see "Improvised Weapons").

Range: A weapon that can be used to make a ranged attack has a range shown in parentheses after the ammunition or thrown property. The range lists two numbers. The first is the weapon's normal range in feet, and the second indicates the weapon's maximum range. When attacking a target beyond normal range, you have disadvantage on the attack roll. You can't attack a target beyond the weapon's long range.

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