Charring Smite

The next time you hit a creature with a weapon attack before this spell ends, the weapon gleams with astral radiance as you strike. The attack deals an extra 2d6 fire damage to the target, which catches fire and takes 1d6 fire damage at the start of each of its turns. A creature can end this damage by using its action to extinguish the flames.

At Higher Levels. When you cast this spell using a spell slot of 2rd level or higher, the extra damage increases by 2d6 for each slot level above 1st.
