hex staff proc and kills/voice set questions

Hi Arlorians, I've dusted my mage off after a hiatus n am slowly and haphazardly grinding my way through graveyard and mausoleum. I got a hex staff but I notice my kills aren't going up by much (in kdr, not mauso points). Is it to do with the wildfire proc- if mobs die cos of proc, do I get the kills? Or is it that my dmg sucks and others are getting the kills? Is immortal staff the same?

Also, has any mage tried Voice amulet, belt and ring? Is it worth it? :)

Thanks in advance.

I don't really know about the hex staff, but it doesn't matter anyways, as you're still going to use it cuz it's OP.

About the voice set, you should consult Runagain's thread
I remember him saying that he liked 3/5 voice set+speed set
If you can afford the gold, then I would go for immo staff+voice set :)
