Touch of Flame

Fire springs from your hand to burn a  creature you try to touch. Make a melee spell attack against the target. You have advantage on the attack roll if the target is not wearing armor. On a hit, the target takes 1d8 fire damage, and at the start of it's next turn it takes 1d4 of fire damage.

The spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
