Combust

This spell makes a combustible object or creature's combustible equipment burst into flame, even if damp.

If the target is a creature, the initial eruption of flame causes 3d10 points of fire damage with no saving throw. Further, the creature must make a DEX saving throw at the start of their next round or continue to take fire damage.

If the target is a combustible, unattended object, the initial eruption of flame inflicts fire damage on the object as noted before. The object continues to take fire damage until it is consumed or someone puts out the fire.

Anyone touching the object during the initial eruption of flame takes the same fire damage the object does. A DEX save reduces the damage by half. If the creature fails the DEX save it must immediately make another DEX save to avoid catching fire as well.
