I'm interested in building a martial class character that can buy/craft and make use of Bestial Mutagen. Hoping to get thoughts from those who understand the mechanics better on how possible/viable this is.
I'm thinking of a fighter with a shield and heavy armor to offset the AC penalty, agile grace and a monk dedication for flurry of blows.
I'm having trouble understanding whether or not the bestial mutagen's unarmed attacks are eligible to be chosen by a fighter for their preferred weapon group. Are unarmed attacks part of the brawling weapon group if they don't specify, or do they have no weapon group at all? If the mutagen's attacks are not compatible with fighter weapon mastery, I suppose I could take a monk stance to get solid unarmed attacks in the brawling group, though it wouldn't be quite as satisfying.
Also, am I right in thinking I'll be able to buy or craft (with the alchemical crafting feat) enough bestial mutagen to make this work?
Would love your thoughts. Thanks!
