In my last post, I jumped off from Brendan’s thoughts on lighting as encounter with a couple of ways to simulate the passage of time, and as usual my personal favorite is the playing card method. Last night, while perusing the LotFP Rules & Magic book for no particular reason, I started thinking about it some more, and I think there’s more that can be handled by the “four suit” method. (To recap, base encounters on playing cards and torches go out every time all four suits have been drawn.)
First, one tweak I’d make to lighting in particular. I previously suggested that lanterns should run out of oil every other time the four suits are drawn. Even as I wrote this I didn’t love it, as one of the goals of the card method is to keep things very simple: Every time you draw X, then Y happens. I noticed in LotFP, lantern oil lasts a full 24 hours, and while this is a bit more generous than I’m inclined to be, it did lead me to my solution. Every time torches go out, there is a 1-in-3 chance that lanterns run out of oil as well. This makes lanterns theoretically infinite, but the odds are low.
