Ember Thread

You spin a thread of flames, then send it out toward a creature or object. The target must make a Dexterity saving throw or else they are ensnared by the thread and take 1d4 fire damage. If they take any form of movement, the thread snaps and goes up in flame, causing them to take an additional 1d6 damage. The thread lasts for 2 turns beginning on the cast. If the target is an object not being worn by a creature, it will slowly start to burn.

At Higher Levels. The spell's initial damage increases by 1d4 and the snapping damage increases by 1d6 when you reach 5th level (2d4 + 2d6), 11th level (3d4+ 3d6), and 17th level (4d4 + 4d6)
