Observations:
It's funny as hell watching this guy standing back, with 12 mages, 7
skellies, fire golem, merc and 12 projectile revives fighting for him. I
called him the firing squad because when he has vamps or horror mages up,
that's exactly what it looks like. Abyss Knights are even more fun.
Questing through a2 Hell, only a triple boss pack amde a significant dent in
his army, due in part to the prayer merc and in part to being able to
tele-regroup. The LR at level 30 covers more than a screen. Watching a
boss's life bar go down from a mage barrage is amusing to watch.
Important to note that this build is not as powerful as a traditional
skelliemancer or a meatgrinder, but it's more fun. Granted I'm wearing about
3 Ist worth of gear, but I found or imbued it all. This guy would probably
not benefit from the Infinity I am determined to make, as there's not much I
can't break with LR, and even if I can't break one immunity, the other mages
will hammer away.

Bottom line:
If you're looking for a fun, adequately powerful, versatile Necro build, go
for it.
