Accessories

"There's lots of stuff to play with in RoPH II! My favorite are the accessories, like my plush kitty, Mixter Wiggles! He's my best friend! Nine gave him to me and said he'd keep me safe! Maybe some of these will keep you safe, too!"

Accessories boost various stats and offer some pretty unique bonuses. Even if you find two Crowns, if nobody else wants the spare, you can swap them out mid battle to change your tactics somewhat.

"'Of the many types of Equipment available, Accessories are perhaps the most varied. In RoPH: Original Run, you got three accessory slots with which to equip them; in RoPH II: Raider's Return!, this feature returns, but is increased to Four Accessories being equippable at once.""The most common Accessory type in the world boosts your Stats."
