The rope functions as a Rope of Climbing. While holding one end, you can take a Magic action to command the other end to animate and move toward a destination you choose within the rope's length. It moves 10 feet on your turn when you first command it and 10 feet at the start of each of your subsequent turns until it reaches the destination or you tell it to stop. You can also command it to fasten or unfasten itself securely, knot or unknot itself, or coil itself for carrying. When knotted, large knots appear at 1-foot intervals; the rope's usable length becomes 50 feet, and a creature climbing it has Advantage on ability checks made to climb using it. The rope has AC 20, 20 Hit Points, and Immunity to Poison and Psychic damage. It regains 1 Hit Point every 5 minutes if it has at least 1 Hit Point; at 0 Hit Points, it is destroyed.

Once per Long Rest, you can take a Magic action to command the rope to form a horizontal bridge across a physical gap up to 30 feet wide. It must be able to reach and anchor securely at both sides. The bridge lasts for 1 hour and bears up to 1,000 pounds at a time. It is a firm surface for creatures and objects crossing it. This property cannot make a bridge across a gap wider than the rope can physically span.

After you successfully help reopen a closed route for others, such as by repairing a hoist or establishing safe lines for an endangered settlement, the rope awakens to its Rare stage. Its physical length becomes 100 feet. You can use Line Bridge twice per Long Rest; each bridge can span up to 100 feet, bears up to 5,000 pounds at a time, and lasts for 8 hours. You must complete a Long Rest before using either bridge use again.

After a one-month downtime engineering project dedicated to mapping and securing such a pathway, the rope awakens to its Very Rare stage. Once per Long Rest, you can take a Bonus Action to choose up to five willing creatures within 30 feet of the rope. The rope hauls each chosen creature up to 60 feet along a vertical, horizontal, or angled surface that the rope can physically touch. The movement is simultaneous, does not provoke Opportunity Attacks, and ends in an unoccupied space the creature can occupy. A creature cannot be moved through a solid barrier or beyond the rope's reach.

At level 20, the rope awakens to its Ascendant stage and can expand to 500 feet. Its Line Bridge can span up to 500 feet and bears up to 20,000 pounds at a time. It can be used as an anchor for a drifting cay or collapsing landmass when secured to a suitable anchor point; it does not by itself stop movement or collapse beyond the weight and forces it can bear. Its Ascent property can now target up to ten willing creatures and move them up to 120 feet instantly, subject to the same surface, destination, and barrier limits.
