two spiritual rings combo

[HzVee]

Will both gain +6% matk and +2dex bonus if used together with a soulstaff?
how about the cast reduction? Will it doubles? (+5 soulstaff make 10% reduction) 

thanks for any answer

the combo only works once....if you want the double combo, you should wear 2 staffs, so it's not possible
