Magical Tether

A leash of magical force appears in the caster's hands, which they throw at a target within range. They must make a ranger spell attack; on hit, the creature is snared by the ropes and is tethered. While tethered, the creature cannot move farther than 100 feet from the caster.

The leash is intangible and will not snag or catch on anything; it passes through walls and other obstacles unopposed. It is also invisible to everyone but the caster and the targeted creature, who will both see it as a line of glowing golden force linking the two.

The leash can be pulled towards the caster by winning a contest of Strength against the creature. Similarly, it can be shortened to as little as 5 feet or lengthened to as much as 200 feet.
