You mark the ground creating an anchor point for your target. They then turn invisible and can move freely as long as they stay within 60ft. of the point. Upon attacking, casting a spell, interacting with an object or stepping outside the bounds of the anchor they are immediately teleported back to the anchor and made visible, ending the spell.
At higher levels When you cast this spell using a spell slot of 4th or higher level, the tether range increases by 10ft for each slot level above 3rd.
