Question : Should I use hel widow maker? Or nef widowmaker? Do I have to get 2x ravens if I use widowmaker?

like frater said:
UM is what oyu would really like to go to reach optimal OWs, however, if you can't UM it, either Hel it or -15/res/str/dex jewel works very well. shoot for the UM

what is a ghost sin and how do u make one (can u explain gear too)

ww/trap

i've never made one but here's what I can tell you.

1. they are extremely good PvP GM duels, however they will always lose to a BvB or any other high def / high DR / high dmg char
   
2. they are extremely expensive (claws/helm/rings/ammy)
   
3. you have to be very skilled at PvP to be successful with them

the claws would look something like this: +3traps/20-40IAS/+2assasin with 2os.
the helm would be a +2/20fcr/20-30FRW/Visionary/Res/Str/Dex
the ammy would be a +2/5-15fcr/dex/str/res
the rings (to my knowledge) would be similar to a BvC's (fcr/ar/dex/str/res) though not sure if they use sojs/bks/ravens/etc

you would either go Light Sentry or WoF (which is the most underated skill in the game).

now that i think about it, you will need a Chaos for the WW, so not sure if people go Chaos/Fury or Chaos/the claw mentioned above. anyways, you go enimga, dancers/treks/gores and use MB, WW, Trap to stunlock your opponent. some sins use Widow on switch like a BvC would. try looking on b.net forums for a ghostsin guide, they are very difficult to be very good at, they are costly yet very fun from what i hear.
