Chains of Avernus

You hold out your hand and fiery chains of Avernus leap forward, wrapping themselves around a creature within range.

Make a ranged spell attack against a creature you can see within 60 feet, taking 2d8 fire damage on a successful hit and must make a Strength (Athletics) or Dexterity (Acrobatics) ability check or be wrapped in the chains. A creature effected by this spell takes an additional 2d8 fire damage at the start of each of its turns and cannot move further away from you. As a bonus action on each of your turns, you may pull the creature up to 15 feet closer to you.

An effected creature may us an action on its turn to repeat the ability check, breaking free on a success. If a creature dies while effected by this spell, you gain temporary hit points equal to the spell's level + your spellcasting modifier.

If a creature would use a spell or ability to teleport away, the chains move with the creature unless it leaves the range of the spell.
