Blazing Trail

 You teleport to an unoccupied space that you can see within range. Upon arriving, you unleash a fiery explosion, forcing all creatures in a 15ft radius to make a Dexterity Saving Throw, taking 3d12 fire damage if they fail or half as much if they succeed. Additionally, a 5ft-wide path of fire covers the floor (if there is one), connecting the departure and the arrival point. It deals 1d12 fire damage to any creature that moves through the flames or starts its turn in them. 

  At higher levels. When you cast this spell using a spell slot of 4th level or higher, both the damage of the explosion and the damage of the trail of fire increases by 1d12 for each slot level above 3rd.
