I have a small issue with this card: both 'your' and 'you' can be seen as plural.
Imagine a drill sergeant pointing at a pile of stuff and yell at some recruits "check your supplies, if you have torches you can X/Y" in this case we imagine multiple torches in the pile and the recruits will spread them. Yet if the drill sergeant yells the exact same at a specific recruit, it's singular. So grammatically speaking: both work but context matters a lot. And considering that you can have 1x torches (plurar torchES, and not torch(es) single OR plural) we can consider this to be a set of torches. As such it would make sense for the investigator to spread the torches around so nobody has to dredge through a possibly pitch black trapped and deadly ruin.
Yet considering how brutal the game is, I'd imagine that this is meant at a single investigator and only if they have it in their supply the can do the action. So unless I missed a rule regarding the supply somewhere, rules as intended vs rules as written is a bit unclear IMO. Maybe saying "if you, or an investigator in your location, has torches in his her supply" or simply "if an investigator has a torch/torches in his/her supply" would be a lot more clear, cause at this point logic could dictates that my buddy gives me one of the torches he has so I can use it in the dangerous, dark ruin xP Anyone know if I'm missing a rule somewhere that would affect this?
