Aerial Lasso

You conjure a shimmering magical lasso that you can use to snare a flying creature or object within range. The lasso is connected to your hand by an ethereal rope, allowing you to pull or be pulled by the target.

Lasso an Enemy: Make a ranged spell attack against a flying creature within 120 feet. On a hit, the lasso wraps around the target, and you can immediately pull the creature up to 30 feet in a straight line toward you. The creature is restrained by the lasso for the duration. On each of your turns, you can use your action to pull the creature an additional 15 feet toward you.

Lasso an Ally: If you target a willing flying ally or object within range, you can choose to be pulled toward them instead. You are pulled up to 45 feet in a straight line toward the target if you are lifted off the air in this way you can continue to use your action on your following turns to pull yourself along the lasso's length the same amount of feet as you movement or climbing speed (Your Choice), remaining connected to the target for the duration. 

At the end of each of its turns, a creature restrained by the lasso can make a Strength or Dexterity saving throw (its choice) against your spell save DC to break free, ending the spell on a success.
