Effect

The target must succeed on a Constitution saving throw or take 4d4 fire damage and be tethered . A tethered creature takes 2d4 fire damage at the beginning of each of their turns. A tethered creature can repeat the saving throw at the end of each of their turns, ending the effect on a success.
For the duration, if the target is an interdicted creature, you can use your reaction to burn one of your seals on the creature . When you do, the creature makes their next saving throw to end this spell with disadvantage .
