Been on a kick lately hitting all the majors with each spell I make, so we have to do DnD 5e!
Fist of Flame
Casting Time: 1 bonus action
Components: V, S, M (piece of coal)
Duration: Concentration, up to 1 hour
You wreath the targets hands and feet in fire. Unarmed melee attacks from the target do an additional 1d6 fire damage on a successful hit. The fire provides light up to 30 feet.
At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for every two slot levels above 1st.
