#2 - around 10fg
#3 - 30+ fg
not sure about #4...
#5 maybe 5fg
#6 put it on lvl 90+ char and post how much mana it adds.
#7 - not that good...misses fhr / 2sox or much more life. But wait for another opinion on this one mate.
Gloves each maybe 5fg...I'd only keep them if they got str+dex both above 10 and/or manaleech / java sks
