What to stock up on?

What are black crystal prices at on sea? :\

no1 really care bout this jewel/crystal yet...
as we do nt haf chaos scroll, most ppl do not knw the benefit of using dark/black crystal..so, ppl arnt really go and upgrade this...
most of my frend that making the reverse weapon is also saying tat they do nt wan to risk thier 1st evan lvl 120 weapon by using dark/black crystal..so the only jewel tat goin up would b diamond/sapphire and those str/luk/wis/dex crystal..

btw..becox of epic content bein patch, most ppl arnt really go for maker skill yet..most of thm still havin fun at mulong dojo, TT and huntin maple eqp...
