PSA: Area level 80+ is ruining your waystone sustain

FIXED IN LATEST PATCH: GGG confirmed that areas above lvl 79 were trying to drop waystones that didnt exist

I wanted to make a video on 100 juiced endgame bosses, so tier 16 with +2 to area level to bring it up - and i realised i was getting next to no waystones. Which was weird, because on the way to farming the boss atlas passives i was getting around 2 tier 15 waystones per map boss without fail

So i did some testing and found out that area level 79 is guaranteed to drop tier 15 waystones from max level difficulty bosses - and the more waystone drop chance you have the more guaranteed t15s the boss will drop. For example 400% will likely drop 3 tier 15s from the boss without fail and will drop a minimum of 2. I recently dropped 8 from a map that had around 600% drop chance and two bosses

But area levels higher than 79 do not have this guaranteed waystone drops from bosses, i ran around 20 ilvl 80/81 bosses to test and got 11 tier 15s overall with only 3 of them dropping from bosses. In around 70 area level 79 boss maps ive dropped more than 300 tier 15 waystones and every single boss dropped a minimum of 2

So, area level 80-82 is ruining your tier 15 waystone drop rate through bosses, i dont know if this is the case through other mechanics and regular mobs or if its just the boss specific drops (although if i had to guess id say it is the case where it ruins sustain through all mobs, since i should have dropped a lot more tier 15s from the rares i was killing in my area level 80/81 maps)

But if you need tier 15s the sweet spot for boss nodes is area level 79
