You target a creature within range, that is wearing pants or undergarments, forcing it to make a dexterity saving throw. On a failed save, the creature's pants will catch on fire and they will take 1d4 of fire damage. Until they are extinguished, the creature will use their turns to put themselves out, rather than fight, running to water or other ways to put out the flames. While the creature's pants are on fire, they will take 1d4 fire damage at the end of their turns.

This spell's damage increases by 1d4 for each spell slot level above 1st.
