Tether of Morse

A spectral rope lunges from you at a target within range. Make a ranged spell attack against a creature or structure you can see within range. If you hit, you become attached to the target, and you can't be further away from the target than you currently are. On your turn, you may use your action to increase or decrease the length of the tether out to a range of 60 feet. If the target is a creature it drags you if it moves further than the tether allows, and it doesn't need to expend extra movement when dragging you this way. The spell lasts for the duration, until you dismiss it (no action required) or a creature within 5ft of the tether makes a Strength check against your spell save DC to dislodge it.
