I am trying to collect every katana so...

I'm unsure if there is a katana for this dungeon but I assumed there was since I got a drop from Vault (57) and Great Gooble Library (59), both were from chests, not from the guaranteed item. I'm not sure if excluding weapons was intended but I'm more than upset to see my time was wasted. :'(

Guaranteed gear don't include weapon.

Poor wording in the translation, other languages say armor and accessories, not weapons.
