I think to make things easier I'll just say that the PRG cannot be used to craft weapons of any kind. Its purpose is for building shelters, survival items, and ship parts, so those are probably the only things it is programmed to create.

The tranq darts will make ordinary people sleep for 2 posts or one minute, I'll edit that in.

I'd be happy to pay to have a steel knife with some of my starting GP, it doesn't make much sense for my character to have iron.
