Item Guide Completion
I'm re-playing it now. I haven't found that weapon yet, but the armor #178 Guardian Armor is in a treasure chest at the Ruins Where Devils Gather, and armor #187 Leather Dress can be purchased at the weapon shop in Radus.
EDIT: Found #92: "Meteograph" in a treasure chest inside of the comet.
