As a part of a module, our low-level party was sent on some random island with just 10 gp worth of gear each. The logical conclusion from that - as long as we want to have good stuff, we have to do it ourselves.
My character has some ranks in Alchemy and Poisonmaking, so he can do some nasty stuff even in the given situation - but I need to be sure that I understand the alchemy rules well enough.
I assume that if PC can't buy or use someone's else Alchemy Lab, he is stuck with -2 to his roll since he is improvising. If he gets other people to help - how much he gets for any trained helper? What about untrained? And does he really need to make every Acid flask for several days of doing nothing but this (unless he rolled enough to shorten the item creation time)?
