I had an idea for a system that works similar to reforging and magian trials, where you collect pieces and upgrade items, and upgrade them one tier at a time.
Gear and items purchasable from the infamy npc inside the feretory, then upgrade-able from the suspicious npc in passhow marshlands. (Gotta be more use than just unlocking monstrosity.)
Base Pieces and upgrade items:
[Monster Rank or higher]
Old Belt (1000 infamy)

Def:1
Lv.10 WAR/RDM/THF/PLD/DRK/BST/BRD/RNG/SAM/NIN/DRG/BLU/COR/DNC/RUN
