Binding Fyre

One creature that you can see within range must make a Dexterity saving throw. On a failed save, the creature is bound to you by a tendril of fire.

For the duration of the spell, neither you nor the target can move or be moved to a point more than 30 feet away from the other. If one of you teleports to a point beyond this range or travels to another plane, the spell ends.

At the end of each of your turns for the duration, you and the target each take 1d8 fire damage. This damage can't break your concentration on this spell.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage the target takes increases by 1d8 for each slot level above 2nd.
