Tether

An invisible, ethereal magical rope attaches to two points you can see within range.The caster can use a bonus action to shorten the tether to a minimum of 5 ft or lengthen the tether up to a maximum length of 120 ft. Once attached, the tether moves through solid objects and creatures. For the duration, the points cannot be moved further away from each other than the length of the tether. If either of the points is a creature, the creature can choose to make a Dexterity saving throw to avoid becoming attached. Once attached, a creature can break the tether at the end of its turn by succeeding on a Strength saving throw. The tether is also broken immediately if the creature enters another plane of existence or teleports. Creatures immune to the Grappled condition cannot be affect by this spell.
