so what i am getting from recent posts some one is mad cause you can pull off magus, slayer, brawler, warpriest, white mage, bloodrager, ect just using the core rule book.
I understand the worry they won't do those classes now. but i have a feeling some of them they will. simply cause class features are still a thing.
so how i am getting this skill checks should mostly be used if criticals and failure outcomes apply. when you make the challenge you think of the lvl of the challenge (who made it ECT) then how hard it is to accomplish unmodified (if the party is just going bullrush it) if they can find ways to make it easier you can then lower the dificulty.
I like it
well i made a crazy natural attack character. 1 level white haired witch/ rest armored hulk (barbarian). the RP to go down are beast totem and elemental rage. gear to look for tentacle cloak once per day 2more natural attacks, dreadwing fulplate 2 wing attacks and flight for half your armor bonus, and obviously amulet of mighty fists.
by level 10 with the items you are looking at 6NA when not raging, 9NA when raging, 11NA when using cloak
one of the titan archtypes (+1 size). tiefling with fiendish heiritage feat (may want to consult dm to see if you can skip the roll and just take one) to get you large limbs (+1 size) perminancy enlarge person (+1 size) impact (+1 size) this sets you up for 8d6 with mythic you can use enlarge person mythic to push it to 12d6 i recomend going with vital strike after all of this. best way to improve the damage for the build.
race skinwalker (wear bore) gore attack adopted trait, tusked trait
focus on barb tell lvl 11 then go into rogue (scout,thug) rest of the way for sneak attack. some point pick up a wyvern cloak gaining a stinger and by the end of this you will have 6 primary attacks and 2 secondary, you can charge the attack and still have full round attack charging a person lets you sneak attack start your attack with your hair so you can atempt to grapple
skinwalker wearboar gets you gore/ 2 hooves feral mutagin for bite and 2 claws lvl two looking at 6 attacks 4 primary 2 secondary there is an archtype to alchemist that replaces bombs for sneak attacks witch for this crazy amount of attacks can be worth it.
also if you want the claws and bite away from feral mutagen their is a race trait for orcs called tusked you can get it with the trait addopted then go 2 lvls of ranger for natural attack style it gets you 2 claw attacks
you could actually go for a skinwalker race. wear boar. this will give you 2 hooves. with a race feat you can get a goar. with adopted (by orcs) trait you can get tusked for a bite attack
2 lvls of ranger you can take aspect of the beast for 2 claw attacks if you still have the wings that will leaves you with 8 attacks at end game look for a wyvern cloak that gives you a stinger attack bumping it up to 9.
(this next bit depends if the dm considers no extra attacks count towards natural attacks)
