Here is what it is said to affect

Hunter - In combat, you do 75% more critical damage against animals and mutated animals.

I understand that it affects geckos and such, but what about deathclaws and centaurs? Do they fit into the animal and mutated animal category?

If so this is a very powerful perk.

Nah theres also a perk called purifier that affects damage or critical against deathclaws, supermutants, and centaurs, and spore creatures.

So they fall under that category not mutated animals. sort of.

I think that the really nasty mutants are classed as "Abominations" whereas the rest of the wildlife is "mutated animals".

Yeah not so sure how they classify or name them as.

I got those names from the strategy guide information.

I'm gonna go with the rest and say they probably identify "animals" the same way the "Animal Friend" perk does, excluding Deathclaw and the like.

Well, in F3 deathclaws were not considered animals, so they probably wont be effected by this perk.

OH NO Ninja'd :ninja:

Centaurs are in again? Eww.
