Re Jonast
Maybe for a period of time sunqua used to drop out of noob island ? It's possible but i dont know. I dont think so tho, would be weird to modify the drop location of an item, everything prenerf is related to stats/icons/names.. from my knowledge.
Nowadays they for sure don't drop out of noob island at least we can say so seeing the amount of chest run every one did on this website
Both the afflicted even if lvl 18 dont drop them for sure also.
Am thinking that in the explorable area of zendaijun, there is a few stone Kirin tho, they drop sunqua and all basic skins. But they aren't lvl 17-18 am pretty sure.
I guess maybe bogs beast is the one who dropped them ? I guess there is very very less sunqua q7-8, maybe less than crystallines ? (Lul :p )
There is maybe more to this, maybe mobs level have been change ? Lul intresting mystery tho.
