Actually, what I'm noticing that is that the RNG for the game will already predetermine what several kinds of gear it can be based on the combination of vocations for you and your pawn. Last night, I had this issue:
I had two Lv3 Weapons and here's what happened when I purified as the following classes:
- Assassin/Sorc = Lv3Ranger Bow & Lv3Archistaff
- MysticKnight/Mage = Lv3Archistaff & Lv3Archistaff
- Fighter/Fighter = Lv3Mace & Lv3Hammer
- Strider/Strider = Lv3Daggers & Lv3Bow
- Mage/Mage = Lv3Archistaff & Lv3Archistaff
I did some of these twice and got the same result. It seemed more predetermined than I thought after the vocation trick. This totally sucked, I needed a Lv3 Mage Staff and kept getting the Sorc version. I did get my Lv3 Daggers and Bow though which was nice.
