I will type up all of the things my summon necro has. He fares well in Hell by himself so if you do what I say, you should be good.
Gear:
Full Trangs
Arm of King Leoric Tomb Wand
Golemlord's Amulet
2 Nagelrings but I suppose it would be better with 2 SOJ's
I don't currently have any good boots but mine are Tearhaunch Greaves
Also get as many +to summon skills charms as possible and a hellfire torch

Stats (At lvl 76 no gear):
115 strength-stop at this
25 Dex-No points into Dex at all
290 Vitality-never stop putting into vitality
25 Energy-No points into this at all

What I did was alternate putting 5 into str and 5 into vit untill 115 str then just put all future points into vit

Skills:
I know this will sound weird but my necro rocks and this is how I did it.

Alternate between putting a point into Raise Skelle and Skelle Mastery untill they are maxed out. Next, max out Raise Skelle Mage. There you go! After you are done maxing those out, put some points into stuff so you can do Summon Resist. With all my armor on and charms, this is up to 18. This is plenty b/c after that, the bonus gets so small each point it isn't worth it. If you are going to put any points into curses, put a few into Amplify Damage. You would be surprised at how much more your skelles murder with this in effect. You can do what you want with the rest of the skill points.


All together, my necro has the following with all his gear on:
Skills:
37 skelle mastery and raise
36 Raise mage
I have just played around a bit and have a +14 to all summon skills so the others I have just put 1 or 2 skill points into.
15 Amplify Damage
And I never bothered with poison and bone.

Stats:
158 str
58 dex
303 vit
38 energy

I have 819 health and 592 mana. While it does take a few mana pots to get all my guys summoned, my recharge rate is high enough that if I kill a few guys, I don't need to pot.

Good luck with your runeword free Necro!

(There is a reason why this is a skelle necro, in case you didn't notice, I fucus on skellies)
