Torches wont make Natural Gas explode
I’ve played this way, that and enviromines: torches-set-everything-on-fire configuration. You would be surprised how many different variations of alternative lighting you can come up with.
Jack o’lanterns were a cheap and effective means of protecting your flame, I would use vinteum torches too as they wouldn’t react and gave a pretty blue colour, but the resident mage would throw a fit when I used up all their precious dust on aesthetical lighting.
