1) The revised beast friendship proficiency describes how the identify plants and fauna throw interacts with the friends of birds and beasts class power, but how does it interact with the naturalism proficiency?
APM: Rules-as-written, it doesn't. Do we think it ought?
Naturalism (G): The character is knowledgeable of common plant and animal life forms in terrain typical to his background. The character is familiar with edible and poison foods, healing herbs, and signs of unnatural danger (such as unusual quiet, atypical animal behavior, etc.) in his known terrain with a proficiency throw of 11+. This proficiency can be selected multiple times.
Looks like I was reading Naturalism wrong. I thought it let you ID plants and animals in your native terrain on an throw of 11+. It looks like it doesn't actually provide that benefit. Is that correct?
Naturalism, I believe, is a the gateway to some of the monster harvesting, at least the identification of the parts required or venoms available, starting in Lairs & Encounters pg 135 or so.
[quote=L&E pg 135]
Characters with Naturalism proficiency can identify venomous monsters and distinguish their different poisons with a successful proficiency throw of 11+....Adventurers with Alchemy, Collegiate Wizardry, Magical Engineering, or Naturalism proficiency can identify which part(s) of a monster are typically special components. A proficiency throw of 14+ is required; the target value is reduced by 4 for each additional proficiency rank the character possesses in any of the appropriate proficiencies, to a minimum of 2+.
ACKS page 250 also indicates a Naturalism Throw score for finding various plant toxins (rules on pg 249 for how to adjucate the throw) I'm not honestly sure I'd ever enforce the "typical to his background" in that sort of situation.
If you take the bold part (unusual quiet, atypical animal behavior) and compare it to Beast Friendship saying:
...he can identify plants and fauna with a proficiency throw of 11+...and understands the subtle body language and moods of birds and beasts...
as compared to Naturalism above, it feels like much the same concept, to me at least.
TLDR; Naturalism seems like a better proficiency as a analogue to Alchemy, in utilizing natural resources from plants or creatures for some benefit; with the knowledge bits as a secondary addon.
