Inspired by this.
We already have stuff made from finished crafted stuff (like foods mde of other food), so I thought it may be not bad idea to make something simillar with gear.
like [novice]bat(cave)-cape + 1kg of slime goo = [advanced] cave cape
+ 4x cave louse chitin = [professional] cave cape
+ 2x boreworm hide = [master] cave cape
+ 1x troll hide = [legedary] cave cape
to make things not so OP (and to keep Caveman credo bonus viable) - let these gear to (animal - 1lvl) not aggro you, like novice - keep you safe from cave rats, advanced - from bats, pro - from slimes etc...
Also consider removing armor from gildable stuff (I saw a lot of ppl who just removes such capes (or boots) into inventory just to not loose it - looks kinda ankward).
The REASON is not to make life in caves easier but to remove unneeded tdium, when your 3 minutes task may turn into some unfunny battle-adventure lasting an hour just because all that pretty underground stuff desided to aggro you by sight. So when one killed a cave habitant of higher tier - any kritter from lower tiers just become annoying, not harder and should be avoidable.
