im stack at 9/10 and need one item.
3 Days
(sorry and 100atk items only)
i have 101 boxes
and when i have only
47 i get more eazy open them only with money.
9.100
so im thinking that the more boxes u have the more less chances too open it.
or system makes boxes not open without gold.
tho first time im at 9/10.
