Yes but since I might try to use this jade option for my current character I wouldn't want that to influence the bonuses of this, besides apparently being a weakness of oni all I know about jade is you can tell real jade from fake jade by it being constantly cold to the touch. (My character build is Dexterity, Constitution, Charisma) so I glad it's not tailored for my character (also sense it's from athas, dark sun so it wouldn't make sense to have anything to do with cold damage)
