Vorigan's Burning Hands

As you twirl your fingers, dark teal flames start to dance on your hand. For you they are harmless, emit warmth and shed light.

You can use an action and make a target roll a charisma saving throw (DC 16) and on a failed save be frightened of you for 1 minute. 

As a bonus action, you may touch an object that is not being worn or carried to set it on fire or make a melee spell attack against one creature you can see.

On a hit, the target takes 1d6 necrotic damage and 1d6 fire damage and it is set on fire. At the beginning of each of the target's turns, the creature takes an additional 1d6 points of fire damage until the creature dies or puts out the flames as an action. Another creature can also use their action to put out the flames.

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

 This spell's damage increases by 2d6 when you reach 10th level (4d6), 15th level (6d6), 17th level (8d6) and 20th level (10d6)  .
