If you moved around the FM market, you will notice that there are a lot of fafnir weapons or armors with epic additional potential. There is no secret at all.
Just read at the above chat with my friend.
1. Just fuse UNTIL you get nice add pot like + wa 10 on the first line
2. Then scroll finish that equip, make 1 star (using star force).
3. Then toad to your fafnir weapon or equip. The additional potential stays. There you goes a free wa 10 add pot on your fafnir.
Use fensalirs armors or weapons can already!
