So for the monsters as cohorts I'd just like to know if anyone can give me a formula that matches the example listing for the available monsters as cohorts. There has to be one either based on CR or HD or their effective Monster-as-pc "level", i'd imagine. I was able to figure out how permanency was designed on my own but monsters are different.
Onto the pricing question:
1. If it were up for sale, how might I buy (X) monster? I'll use the Spider Eater as an example. If I wanted to buy one from a dude who had it, what would make the most sense in terms of pricing such a transation? Should I look at planar binding and compare how they price high level outsiders? Ideas please.
2. Can I have help determining the formula used to price poisons. I'd like to use it as a method for pricing "disease samples", which use similar descriptors.
Aside from the leadership question, the point is that I am making a plague spreading alchemist and I'd like mundane options. If I can get a Mummy Rot sample without fighting a mummy, awesome. It isn't like I can go, "hey GM, I need a mummy rot sample. can we fight a mummy in this forest please?" Also, in reference to the Spider Eater, I'd like to buy/obtain creatures that lay eggs in other creatures and/or apply other kinds of afflictions.
PS: Any paizo staff reading this, I'd really like those numbers! THNX XD
Well oddly enough I answered one of my questions:
http://www.d20pfsrd.com/gamemastering#Table-Treasure-Values-per-Encounter
Spider Eater is CR5 encounter. For an APL of 5, an encounter is worth between 1,000; gp 1,550 gp; and 2,300 gp depending on the wealth track set for players. This could be used instead as a scale for "buying" the creatures, with the 3 differing values representing appropriate rarity of the creature in the market/dealer.
Feel free to argue otherwise.
