Theodore's Flaming Grasp

As you hold your hands, with thumbs touching and fingers spread, thin ropes of flame shoot forth from your outstretched fingertips targeting up to 5 creatures in range. Each creature must make a Dexterity saving throw. A creature is Grappled and takes 2d6 fire on a failed save, or half as much damage on a successful one.

On subsequent turns a Grappled opponent takes 1d4 fire damage at the end of its turn, a successful save ends both. 

The fire ignites any flammable objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the initial damage increases by 1d6 and the ongoing damage increases by 1d4 for each slot level above 2nd.
