interesting . i recall picking up the first key but apperantly im blind bc i just checked the Alchemy platform again and i cant find the chest @ Allan. So i went to necro ; noticed i already opened his chest - went on , as spoiler says and i couldnt open up the other two chests . i guess i didnt get the key in necros chest, since you cant even drop the key once you get it
Or i simply messed up the right way by opening necros chest first and got no more keys as a result.
