I play alot in temperate biome with ascendancy or sometimes in desert with rayyas children. Recently I tried to switch things up. I played rayyas children in the temperate biome an tried to go for the monkey shrine.
For the monkey shrine you need 2 dusty tomes. Dusty tomes drop from necromancer Crypts. Necromancer crypts spawn if you have 6000 gold(money not net worth).
Problem: Necromancer Crypts don’t drop dusty tomes in temperate biome, only in the desert.
Thus the monkey shrine is uncraftable for rayyas children, if they are not in the desert.
ps.:I’m very sure it’s not just a very low chance to drop, because as I said before I mainly play in temerate biome. And I have never seeen a dusty tome in all of the playthroughs.
