Infernal Shackle

4-level Conjuration

You conjure fiendish shackles that entwine around a target creature's legs. That creature must succeed on a Strength saving throw or take 6d8 fire damage and have their speed halved for the duration. A successful save halves the damage, and the target suffers no additional effects of the spell. This spell also ignores resistance to fire damage.   At the start of your next turn, if the target creature both failed the saving throw, and has not moved 30 feet or further away from its location when it was first targeted with this spell, it takes an additional 4d6 fire damage, is pulled back to its starting location, and then then the spell ends
At higher levels: When you cast this spell using a spell slot of 5th level or higher, the initial damage this spell deals increases by 1d8 per spell slot level expended above 4th.
