Curoch - Githyanki greatsword
Weapon (greatsword), artifact (requires attunement by a creature the sword deems worthy)
Art credit: Katsuobushield
Taken from an illithid lair, Curoch is a sentient silver greatsword of githyanki design. Infused with the psionic powers of his former users, Curoch grants power to whoever it finds worthy. To spare those weak of mind, those without innate psionics, Curoch holds back, only releasing just enough power to not crush the mind of its user.
Attunement. Curoch is a sentient magic item who attaches itself to individuals it deems worthy. If someone is found to be worthy, they can instantly attune to the sword, without requiring a short rest to do so.
Curse. Curoch does not release its users and it limits them to only use it as a weapon. A creature attuned to Curoch takes 1d4 psychic damage when it makes a weapon attack with anything that is not Curoch.
Bond. A creature attuned to Curoch always knows the direction and distance to the sword. As long as they are on the same plane of existence.
Sentient. Curoch delivers its emotions through telepathy, with a range of 30 feet, to its chosen host. Curoch wants the world rid of the illithid, it wants freedom, it wants to escape the darkness.
Limited Magic. Curoch laid dormat for centuries, it used most of its power to escape the illithid lair. It must recover to be powerful again. Curoch does not count as a magical weapon when attacking creatures resistant or immune to non-magical weapon attacks.
Psionic Attack. When attacking with Curoch the user can decide to deal an additional 1d4 psychic damage.
This trait can be used a number of time equal to the user's proficiency modifier. Curoch regains all expended uses when the host takes a long rest.
