Best place to farm them?
I go for floor 181
Repeat the map atleast 50 times and you will have abt 250 of each(based on my exp)
Floor 300-400 with crushing flames and crystalline. Although floor 500 also since you get a ton of kyanite which you can salvage into Larimar. Diamonds most common at floor 300 of 400+ .
Okey, gonna try both, its kinda hard to convert maps to such levels tho
Ikr. lot of trial and error just to get floor 500+.
I never loot diamond at floor 252+
