Weapon spirits live as long as they are not killed, and do not die from natural causes. A Weapon spirit has a physical appearance of an age determined by its creator for its entire existence.

Your Constitution score increases by 2, and one other ability score of your choice increases by 1.

Weapon spirits are rarely chaotic, tending to remain loyal to their creator and their purpose.

Weapon spirits share the same height and build as humans and elves. Your size is Medium.

Your base walking speed is 30 feet.

You have two creature types: construct and humanoid. You are affected by an effect if it works on either of your creature types. However, you cannot be mended to heal hit points.

You were magically linked with a weapon at your creation. This can be any weapon you are proficient in. When not being held or sheathed the weapon hovers within 30 feet of you and you can recall it into your hand or move it to any space within 30 feet of you as a bonus action. You can link to a new weapon you are proficient with over the course of a short rest, this weapon must remain within 5 feet of your linked weapon. If you are killed your body disappears and your linked weapon is considered the dead creature for spells that would return you to life.

Your consciousness assists you in helping your allies even when you are within your weapon. If an ally uses you to attack, they can use your modifier for attack and damage rolls. This cannot be done while your physical body is outside of your linked weapon.

You do not need to sleep nor eat, but you must spend at least six hours of your long rest inside of your weapon. While in this state, you have the traits you would normally have while within your weapon.

You project your physical body from your linked weapon and as such you cannot move more than 30 feet away from your linked weapon. If you or your weapon is moved more than 30 feet away from each other your body disappears inside of your weapon. While inside of your weapon, you can't act, but you have hearing and blindsight with a 30 foot radius as well as resistance to non-magical bludgeoning, piercing and slashing damage. You can leave your weapon as a bonus action and enter it as an action.

You can communicate mentally with another creature that knows at least one language within a 30-foot radius. This creature doesn't need to share a language with you but unless they have telepathy themselves they can only receive and respond but can't initiate or terminate a telepathic conversation. You must be conscious to use this trait and cannot telepathically communicate with multiple creatures at once.
Languages. You can speak, read and write Common, Ancient, and one other language of your choice.
