Crimson Dawn (5e Equipment)

Weapon (scimitar), legendary (requires attunement by a creature of a lawful alignment)

Crimson Dawn is a magic scimitar with a jet-black blade and a blood-red hilt inlaid with three rubies of equal size along each side. In places, the black blade is marked with red, and the pommel is made in the shape of a rose, crafted from ruby. Many great warriors would kill to have their hands on this blade.
You gain a +3 bonus to attack and damage rolls made with this magic weapon. The weapon also functions as a scimitar of speed. You can also use an action to cast magic missile at will as a 1st-level spell.
Sentience. Crimson Dawn is a sentient lawful neutral weapon. It has an Intelligence score of 21 (+5), a Wisdom score of 18 (+4), and a Charisma score of 25 (+7). It has hearing and darkvision out to 120 feet. The weapon can speak, read and understand Common, Draconic, Dwarvish, Elvish, and Undercommon, and can communicate telepathically with its wielder. While you are attuned to it, Crimson Dawn understands all languages you know.
Personality. Crimson Dawn is quick-witted and loves to make jokes, but is deadly serious in times of conflict. It has an intense hatred of creatures from the Underdark, though not deep gnomes, and refuses to allow them to attune to it. Conflict arises during the next dawn if the wielder allows creatures from the Underdark to perform evil acts.
