hey guys
i have noticed some of us have already 15/15 NNI gear and my suguestion is:
Lets ppl exchange astrariums for alexandrites, any number of alexandrites we can get is gain.

Our current system is

Bronze astrarium (+1 armor): Defeat floor 20 boss 5 times.
Silver astrarium (+2 armor): Defeat floor 40 boss 5 times.
Mythril astrarium (+3 armor): Defeat floor 60 boss 5 times.
Gold astrarium (HQ armor): Defeat floor 80 boss 5 times.
Platinum astrarium (HQ armor): Defeat floor 100 boss once.

and my idea here is

Bronze astrarium (1 alex per key item): Defeat floor 20 boss 5 times.
Silver astrarium (2 alex per key item): Defeat floor 40 boss 5 times.
Mythril astrarium (3 alex per key item or cotton): Defeat floor 60 boss 5 times.
Gold astrarium (4 alex per key item or cotton): Defeat floor 80 boss 5 times.
Platinum astrarium (Linen cotton): Defeat floor 100 boss once.

this only should be an option for ppl with 15/15 on gear if you dont have 15/15 you wont able to get the option where you can exchange key items by alex
