Hey, I'm Rob and am new to this forum.
I have a BRP book and have learned a fair bit from it, but I was looking over the examples of poisons, each having a description of symptoms and a potency number. The thing is, it doesn't tell you how to apply this to any poisons or venoms not in the book, so my question is; how do you figure out what value a certain poison may have? How would you know what to compare it to?
I ask because I'm writing up my own game and some classic creatures have been altered to take on my own twists, some including venom/poison. The problem is, while I have the symptoms written up, I have no idea what would be a fair potency to apply to each. Are there any guidelines I can use? Do any of you have tips or something I can work with?
I'd really appreciate if you can help me out here, since randomly allocating a value would end up either becoming stupidly powerful or not powerful enough.
