i like the general outline of this guide as i used it to build my necro.
after playing with it for a bit, i've edited it a little bit and i seem to be doing a lot better.
here's what i've changed:
circlet instead of shako
i get:
2 pnb, 20 fcr, 17 res, 30~ life, 50~ mana, 1os with um rune.
i would like to use a 3/20/2 with um/um or um/jah.
hoto instead of wizspike: for +skills, adds about 600 dmg to spear/spirit
only use one FCR ring as opposed to needing two...
i use 1 FCR ring with str/resists, and then other ring is SOJ/dwarf/sorb choice.
i do not try to hit the ridiculous 152 breakpoint as some other user has mentioned, i hit only the 86 and i do fine.
i stack 10x20 lifer scs instead of 10x5 fhr scs. necros need life badly

with this set up i hit about i think 45/75/75/75 resists and then i hit about 2400 life using a 4 BO CTA.
i'm using 9xPNB plains right now, but i'd like to shoot for 30 lifer PNBs in the future.
Necros are fun but I have a hell of a time against sorcs and hammerdins.
Much more fun than my old pvp auradin character.
