Flamelash

You lash out with a tendril of flame at a creature you can see within range. The target must make a Strength saving throw. On a failed save the target becomes restrained by the tendril and takes 2d6 fire damage. A creature restrained by the tendril takes this spell's damage again at the end of its turn. A creature restrained by the tendril may repeat the saving throw at the start of its turn, ending the effect early on a success. The spell also ends if the target is ever outside the spell’s range or if it has total cover from you.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
