Hunter Gear Save for Hunter weapons
Right rings that imitate Critical Strike, Perfect Keeper, PP Convert, Killing Bonus, Massive Hunter, Photon Flare, and EPPR field. Restrictive on what classes can equip them. (There's a tease that you could manipulate class combos to have rings stack with their original skills?)
Boost Slayer, a skill that was in the datamine for quite awhile, is now a skill ring. Equippable on all classes. Sounds like the Challenger skill in MH.
DS Kamaitachi only has a chance to occur, not guaranteed. TD Chase sounds best for fighter left ring IMO.
