NOTE: if there are any typos or any suggestions for the refinement guide, please post it here
also: i won't give any support for the dupe hack, please post it in the dupe-hack thread
what you need:

Many refinement materials, at first levels you'll need like 1 or 2 dragon bloods but i still recommend 30 or more, especially for the last refinement materials
30kk - 50kk gold, it's depending on your luck but it shouldn't be more than 30kk gold overall
so lets start:
a table for the refining succes:
Congratulations, you have made your own +12 weapon
other notes and thanks from me:
- making a level 12 weapon can take from 45 minutes to 2+ hours, depending on luck, your internet connection and your computer
- always search for a good hidden place to dupe your weapons
- if you have questions, post it here
- press the thanks button if i helped you, since i put much time into this guide
- also thanks to GoodOldJase for his great tutorials and the dupe hack, without it, i wouldn't probably play anymore
the rest is up to you
