Val's Igniting Embrace

You teleport yourself to an unoccupied space you can see within range. Immediately after you disappear, a flaming simulacrum of you appears in the space you left, and reaches out to grasp a creature of your choice within 5 feet. The target creature must succeed on a Strength saving throw or be restrained until the spell ends. At the start of each of its turns, a creature restrained by the simulacrum takes 4d6 fire damage. A creature grappled by the simulacrum can use an action to make a Strength or Dexterity check (its choice) against your spell save DC. On a success, it frees itself and the spell ends.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d6 for each slot level above 5th.
