Dart 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.

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.

Thrown: If a weapon has the Thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the Finesse property.

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.
