Fist Disc(s) [Possible Spoilers]

[Guntram]

Okay so, I spent quite a while on Free Missions right before the final level so that I could save for 2 S-Rank weapons (Bought Fists and Sabers) with Lucaim Nav and some missions with Tonnio, and despite doing so many missions (I did De Ragon alone at least 10-15 times) and getting S-Rank every time, Lucaim never gave me a new Fist Disc. Any ideas or anyone know how to get another Fist Disc? Thanks

I believe its a 10% chance of getting an item from npcs. Its not all that uncommon to not get the disks by now. Its unlucky yes but not impossible. Im afraid perseverance is the key here. Still shouldnt take too long as De Ragan shouldnt take more than 4-5 mins a run. Nav will eventually give up a disk.
