The bruma torch is a possible reward from a supply crate, which is obtained from subduing the Wintertodt.
The torch acts as an equippable light source and as a warm clothing item in the Wintertodt boss fight. The torch works as a light source unequipped, and can be used to light braziers instead of a tinderbox in the Wintertodt's prison. In addition, it can be used to smoke deadfall traps.
The torch DOES NOT cause explosions in the Lumbridge Swamp Caves if used as a light source.
If the player has three bruma torches in their bank and/or inventory, supply crates will instead give a torstol seed when it would have given a torch. Players can also trade in bruma torches for an extra supply crate or 50 burnt pages via Ignisia. As the Grand Exchange price of 50 burnt pages is currently 163,400 and the price of a torstol seed is 60,850, it is generally better to exchange torches for burnt pages unless you are an ironman who wishes to receive torstol seeds.

Same for torches and the torstol seed. It's an unusual bit of code, but looks intentional."
