Well, I see some CASH set pieces for sale for between 10-20 million, so being optimistic the set could cost under 100mil. The weapon is about the same price as the whole set, my question is whether the effects are good enough to be worth that. I don't really know what they are since they're in korean.
I already got +6 and +7 everything except gloves, and still seems to be pretty low stats. I don't see what else is left aside from CASH sets or accessories (got 3 from bosses)
It's been incredibly hard to see normal equips for sale, all I see nowadays are CASH sets. About a year ago I used to see normal equips with better stats than mine for about 10mil or so, but they seem to be gone.
