Arcane Tether

 You conjure a rope connecting two points. Choose two objects or creatures within range (You can chose to target yourself). If the targets are within 60 feet of each other, a magical tether links them together. An unwilling target can make a dexterity saving throw, ending the effect on a success. When tethered, the targets cannot be moved beyond 60 feet of each other, as a magical rope holds them back. This rope also breaks falls, can be swung on, and be used to pull either target. When you cast the spell, and as a bonus action on each of your turns, you can choose to expand the rope up to 60 feet, or contract it up to 10 feet. A creature can use its action to break the rope by making a strength check, contested by your spell save DC. On a success, the tether is broken and the spell ends. You can end the spell early as an action.
