Long time ago some of the pred mutations like claws or fangs had cutting characteristics. So basically if you had evolved to be able to do it then you could butcher corpses without carrying a knife.
I get why they changed it after all claws are for grasping and fangs are for killing but i really think that this leaves an important niche unfilled. I really like playing a super primitive, naked, freakishly huge beast mutant and i play completely naked and just have a few simple items around my den for crafting. Its a nice fun and challenging way to rp for me.
So maybe instead of just adding that characteristic we can add a couple post threshold mutations on all of the carnivorous branches that are like “carnivorous teeth” (ie carnassial teeth those are specifically evolved to shear meat from bone) that will allow the player to consume a corpse directly and something like “carnivorous digestion” which removes the health penalty for eating raw meat (carcasses).
If we are going for realism it doesnt make much sense that a huge carnivorous mutant would be unable to eat its meal. The predators they are based on have no trouble and if a mutant has specifically evolved for that purpose than it shouldnt automatically warrant a health penalty. Ofc parasites should still be a thing. Hell even an obligate carnivore negative mutation on felines, beasts and fish (since they are based on sharks or deep sea fish) could be cool where they have to eat only meat (acts as allergy for every other food type) but can extract all dietary vitamins from it and gets a boost to overall calories since they adapted to process it really well.
What do you guys think?
