I've asked a couple of questions about Monk rules lately, but now I'm interested in something I read under the new alternate Barbarian classes, specifically True Primitives. The Trophy Fetish ability lets me attach fetishes from kills to armor and specific primitive weapons the barbarian wields for extra damage or higher saves.
Based on the reading, I've come up with a few conclusions: I can't attach fetishes to shields for any bonuses, and I can't use them in conjunction with unarmed strikes or natural weapons in any way. I'm a little surprised at the list of selectable weapons though, mainly because none of the new Stone Age weapons made the cut.
I am also wondering how fetishes work with piecemeal hide armor. It says specifically "suit of hide armor," so if I'm wearing bone armor(which true primitives are also proficient with) I guess I can't use them, but what if I'm going the piecemeal route and have a combination of bone and hide armor?
First off, the stone age weapons are listed in the Ultimate Combat book where True Primitive is located and rather than saying you are proficient with stone age weapons, they give you a very specific list. RAW you are not proficient but if you bring it up with your GM, they may grant you the proficiency if there is something specific you are going for.
Secondly, as far as the trophy fetish for armor goes, the Trophy Fetish ability only specifically mentions "a suit of hide armor" for attaching your trophy fetish but then proceeds to tell you that if your armor has the fragile quality then once per day you can choose to not have it break if a crit is confirmed on you. This would imply that, Rules As Interpreted, it does work on bone armor because Hide, with a capitol H, does not have the fragile quality but bone armor does.
Finally, as far as using your trophy fetish for natural attacks, the answer is no. You can attach it to one of the True Primitive traditional weapons listed but natural attack is not on that list so you would have to ask your GM for permission in the case of like building Beast Totem, Lesser and wanting your trophy fetish attached to your hands to gain the benefit on your claw attacks.
The OP may not even be alive anymore, I mean do you see how bad he looked as an undead rat all the way back in 2011?
