At the Uncommon stage, the rope functions as a Rope of Climbing. As an action, you can command it to move toward a destination within its length, attach itself to a secure object, or knot or unknot itself. It can secure itself only to a solid object capable of supporting the weight placed on it. While knotted, it shortens to 50 feet and grants advantage on ability checks made to climb using it.

At the Uncommon stage, once per Long Rest, you can use an action to command the rope to form a horizontal bridge across a physical gap no wider than 30 feet. It must be able to reach and attach to secure anchor points on both sides. The bridge lasts for 1 hour, bears up to 1,000 pounds at a time, and vanishes early if either anchor point fails. Creatures crossing it must move along its length; the bridge is not a flat platform and provides no handrail.

After the bearer successfully reopens a closed route for others, such as by manually repairing the Long Hoist or running structural lines to stabilize Linden Cay, the rope advances to its Rare stage, subject to the DM’s approval. At this stage, Line Bridge can span up to 100 feet, bears up to 5,000 pounds at a time, lasts for 8 hours, and can be used twice per Long Rest. Its two uses return when you finish a Long Rest.

After the bearer completes one month of downtime dedicated to such a construction project, the rope advances to its Very Rare stage, subject to the DM’s approval. Once per Long Rest, as a Bonus Action, you can command the rope to haul up to five willing creatures within 30 feet of it. The rope moves those creatures up to 60 feet along a vertical, horizontal, or angled surface it can physically touch, carrying them safely around ordinary obstacles along that surface. It cannot pass through solid barriers, cross a gap it cannot reach, or move a creature unwilling to be hauled. This movement does not provoke Opportunity Attacks.
