Hello..
I'd to ask about how to make dual sword A..
in case, i want to make damascus*damascus sword..
i've read in the 1st page said that it can make by blacksmith mammon but im not really understand about the staps to make it.. n where to find 1x dualsword craftstamp... tq before bro/sis..

craft stamp can only be bought from players - only way to get it is manor system, so only those who have castle can sell it (if i am not mistaken)

to make A/S dualswords, you need blacksmith of mammon, you'll need the swords you want to dualize, some AA (depends on duals u want, find out here on pmfun) and craft stamp.

Imo, A grade duals are worthless....... maybe damascus * keshanberk for their health bonus SA, but anyway, getting recipe and keys for B weapon is pain in ass...... i would try OE B grade duals and then jump to S grade
