Myriadic Edge (5e Equipment)
From D&D Wiki
Weapon (longsword), legendary (requires attunement)
Myriadic Edge is a longsword composed of a metal that seems to be a mixture of mana and several higher quality metals. It is magically sharpened, and often sheds it's mana into the air when unsheathed. People who wield this blade claim it has some connection to other planes of existence, potentially pulling another version of the wielder into the fight. The large mixture of mana and magic within the blade also makes it a good conductor of spells and magical effects.
Cursed. Should you attune to Myriadic Edge It will extend it's curse onto you, giving you disadvantage on all rolls regarding spellcasting. If you cast a spell does not require a roll, make a DC 18 Intelligence saving throw, negating the spell and expending a spell slot on a failure. Failed Spells, or spells negated this way are sucked into the blade, and used to fuel it's powerful ability.
Myriad. Myriadic Edge is capable of rupturing the boundaries between planes. Myriadic Edge has one charge on it, which refills at dawn once every three days. As an action, you may expend the charge, causing your eyes and blade to glow a color related to your character, and Myriadic Edge to summon three silhouettes of yourself from separate planes. The myriads are you, and function as identical copies of you after having finished a long rest with differences only in appearance, personality, gender, etc. The most noteworthy of differences is their unnaturally colored eyes, which are all different colors. Additionally, their copies of Myriadic Edge do not have a charge. The myriads function as their own creatures, and have their own initiatives. They remain in combat for a minute before vanishing back to their planes. They function as a decisive team which the original wielder is considered part of, and treat you and your allies as companions to be heeded and protected at all costs. Should a myriad die, it will vanish back to its original plane of existence with no memory of the event.
