I double checked my math on all your posts, and I did give you an incorrect amount for post #324 with the double losses against the Sages, but even with that corrected you still don't have enough Kumi for this purchase. I think this might partially be due to the draw between yourself and Gutsy giving half Kumi, but even with that included you're still short a little.
Please check, and let me know if you can find out what's happened here.
Arc hasn't started yet, and this isn't where you buy Void Infused Artifacts.
Those purchases get done in the Marketplace, same as before. Go away, hag.
