In addition, there's also Lamia Bane throwing weapon, has an useable enchantment on it that can buff you with refresh, if you want to go that far as to using it.
MAB defo only works in those zones, I used to use it when farming lamia toxophilites as for the refresh, I think it says when you try to use the item charge that it cannot be used in your current zone either that or it works dont think it does though.
