Crescent Moon

Weapon (dagger), legendary (requires attunement)

A dagger with a crossguard in the shape of a waning moon and a leaf-shaped blade. The blade appears translucent, refracting light that hits it. The hilt contains a large polished lunarite gem. The pattern on the gem changes over time, always showing the current phase of the moon.

You gain a +2 bonus to attack and damage rolls made with this weapon.

You can speak a command word ('nox') to make Crescent Moon emit dim light in a 10-foot radius. This light is only visible to you. This lasts until you speak the command word again.

The dagger also has 10 charges. It regains 1d6+4 charges daily at dusk. When you hit with an attack using Crescent Moon, you can expend a charge to deal an additional 2d4 radiant damage to the target. If the target is a shapechanger, they must succeed on a DC 15 Constitution saving throw or instantly revert to their original form.

Immediately after you make a ranged attack with the dagger, it disappears in a silver flash of moonlight and appears back in your hand. Alternatively, you can spend two charges to teleport yourself to the point of impact (an unoccupied space next to the target if the target is a creature), where you emerge holding the hilt of the dagger.

Sun and Moon United

This is one of a set of twin daggers infused with the essence of the Sun and Moon. Each dagger is a formidable weapon on its own, but if wielded together their true power is revealed.

The daggers were crafted by Heimdall as a gift to Freya. How the daggers ended up in mortal hands is unknown.

If you wield Crescent Moon and Shining Star together, you can attune to both using a single attunement slot. They also gain the following benefits:

Empowered: Their bonus to attacks and damage increases to +3 and the DC for their saving throws increases to 18.
From Dusk Til Dawn: Instead of individual charges, they gain 24 shared charges. They regain 1d6+6 charges at both dusk and dawn.
Eclipse: If you miss a creature with an attack made using either dagger on your turn, the next attack you make with the other dagger against that creature during this turn has advantage.
Power of the Heavens: You can spend 3 charges to cast Moonbeam, or 6 charges to cast Dawn, with a DC of 18.
