Anchor (sunken anchor)

As an action you can point this weapon at a point on a surface within 120 feet, causing an etheral chain to run from you to the surface for the next 10 minutes, or until you dismiss it as a bonus action. For the duration you can willingly move closer to the point, but a weight of over 10,000 lbs or a DC 30 strenght check is required to move you further from the surface if you are not willing. On a successful strength check, or if more weight is applied, the chain snaps and the effect ends. The effects ends early if you ever willingly move more than 120 feet from the surface, or if you lose consciousness.
