Blade of Evolution (5e Equipment)

Weapon (longsword), legendary (requires attunement)

This longsword features an ornate hilt forged in the shape of an eyeless, humanoid face. You have a +2 bonus to attack and damage rolls made with this magic weapon. After attuning to this weapon, the face on the hilt morphs into a depiction of your face with empty eye sockets. Attuning to this weapon unlocks it's other abilities.

Adapt. After attuning to this weapon, when a creature that you can see and have damaged with this weapon in the last minute is reduced to 0 hit points, you may choose to activate this ability to enchant this weapon with a benefit based on that creatures type. You may use this ability once before completing a long rest, and you may have up to 2 of these enchantments active at the same time. If you use this ability to gain an enchantment when you already have 2 other enchantments active, you must dispel one of your currently active enchantments. You benefit from these enchantments for as long as you are attuned to this weapon, and all active enchantments are dispelled from this weapon when you un-attune to it.

If both enchantment slots are filled with the same enchantment, the enchantment becomes empowered, and your creature type becomes that of the corresponding enchantment while you are attuned to this weapon.

The face on the hilt of this weapon is always identical to the face of whomever is attuned to it at the time, and changes in real time to mimic any changes in appearance that the attuned creature goes through, whether they are caused by the sword itself, or other effects. When no creature is attuned to the sword, the face remains in whatever state is was in when the previous owner became un-attuned, until a new creature attunes to the weapon.
