[funtomas]

Hello, I have a really bad problem. I did all i had to, and when Reorin asked me, what B grade weapon I'll bring him (for obtain low grade A), I mistakenly choosen Kaim Vanul's Bones  . Is there any chance to deal with it without abort the whole quest? Please, help me!

Its easy since you can trade some other top B-grade weapon for another one at Blacksmith of Mammon. Just buy some top B-grade weapon from someone, visit Blacksmith of Mammon, and exchange it for Kaim Vanul Bones. Top B weapon cost about 90kk. Its better like start quest again. Ofc, you cant exchange duals.
