I've had pretty terrible luck on drops. I got all of the quest gear from earlier in the thread, and all of the available Natimbi gear, very quickly. Unfortunately I ran into a few roadblocks with other things dropping. Ended up giving up and buying a bunch of things on Bazaar to fill things out since I was having such shitty luck farming them myself.
Noita's Boots is proving really easy at 50, the skins don't seem as rare as the other drops in Natimbi for the quests (turtle meat, spectral essences, whatever the fuck you need from the stonemites etc)
Got enough skins for 2.5 boots in the time it's taken to get 2 turtle meat and 2 spectral essences, probably killing more souls than anything.
Easy enough with sk/shm/nec/clr, but easily doable with less i'd say
