A orb of black and red flames appears 20ft above a target within range. On casting a 5ft radius column of flame blasts downwards towards the target from the orb. The target and all creatures within the radius must make a Dexterity saving throw. A target takes 4d6 fire damage on a failed save, or half as much damage on a successful one.

At the end of the target's next turn the orb will move up to 30ft towards them taking the shortest route. Once it has used all its movement or reached the target the orb will fire the column of flames again. It will fire the column of flame even if the target is not underneath the orb.

If the target moves higher than the orb the column will instead fire upwards towards the target to a range of 60ft. If the target moves higher or lower than 60ft from the orb it will follow them vertically also. If the targets moves into a space with a lower ceiling than 20ft it move lower it's height in the most direct manner. If a object gets between the target and the orb (such as a roof) the orb will still fire the column of flame, instead dealing damage to whatever is in the way. 

If the target moves more than 120ft away from the caster or they fall unconscious this spell ends early. 

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 level.
