I don't know if anyone else has experienced this, but in the WoR, when I was in Narshe trying to get Mog, (I don't know if this did anything or not) I had Gogo equipped with the throw command,and I threw a dirk at one of the monsters in town. After the battle i checked my inventory screen and i had three or four slots with: Illumina x75, and three more with dirk x0. I don't know how I did this, but the rest of the game was much easier because of this.
