the last bonus with 6/6 items is 5% crit damage while under the effect of fury. you do not get this 5% crit damage bonus while the buff is on.
also i would like to report the pet buff (rage buff from red moa) does not work every time, even when your standing next to it…also it takes the pet too long to use its skill/buff when it is atking a mob. you end up hitting f2 like 5 times or more to make it use the skill once after a few seconds have lapsed.
