I suggest the following for a different approach.
as for gear: using d web & 3-3-3 darkforce. it will make more sense after you read the next part.
skills: instead of maxing skellys and skelly mastery, use revive and the remaining pts into all of these (fire golem, summon resist, and a small bit into skelly mastery)
the monsters life will be amazingly more than skellys, plus they will always stick of you...
use 9pnb gcs also.
though this build has alot less cast rate you won't even need to move, making fcr basically useless, but some is still needed
you will be an absolute tank...
your nova will bring them down to 1 life in less that 4 seconds, your fire golem's aura finishes them off before they can run into town
the only characters that can kill you are the following:
chargers, windys, some fireballers, and fohers.
this build makes it impossible to lose to a hammerdin, barb, zon, or fellow necro
