Ok, so if you wanna know how much it really worth...
I agree with
MMMartin, it's not best staff at all.
High-End quarter staff can be demon slayer with mana and stamina,
then you can farm in doom artyes really quick. This staff: HLD - no need if use glasses, better will be HLA.
Also every monster that you can kill with this staff, can be killed with more simple 3 mod staff.
So if you post a selling thread, you will probably get an offer 4kk, maybe max 8kk or CC (maybe).
From my experience on the selling/buying forum, no one will buy non-slayer quarter staff for more
gold than that. Maybe before the last lottery event you could sell it better, who knows.
