Sorry I saw this thread too late. I answer now.
If you're going to be a pure summoner for pvm (and a pure summoner pwnz ALL in the game without no problems), you have to max mages, cuz they are really helpful against physical immunes and against physical immunes whose immunity can be removed by curses, cuz their physical resist after the removal remains high and the skeletons can be very slow to kill them (Wraiths, for example, or other immunes).
If I had to go strictly pvm and I wanted to use summons, I would certainly max these skills:
- Raise skeleton
- Skeletal Mage
- Skeleton mastery
- Corpse explosion
I would give 1 point to Amp and Decrepify, and 1 to Bone wall, Golem mastery, Clay Golem and Summon resist. I would NOT waste points into Revive, cuz Revives are too stupid, and totally useless. The remaining points are your thing: you can go for Bone wall to get a better absorbption rate on your Bone armor, or for Clay golem to have more life / stats on him. But trust me, Revives are a waste of time, mana and skill points. If you really don't know how to put remaining points, go for bone spear to gain some magical damage while your minions fight, but I repeat: Revive SUCKS.
Fire golem and Blood golem are the worst golem of the game. They can't just kill or be useful. The only useful golems are Clay (for slowing enemies and cuz it has tons of HP = a real tank) and Iron, cuz it can be made from an item which has aura on equipping, and can have that aura after it's been raised.
And this is the gear I will use for a summoning necro (like the one I just wrote above):
Enigma Light plate
Shako [Um]
HotO Flail
Boneflame +3 [Um]
Marrowwalks (bug = pwnage for your absorb rate on BA)
Trang gloves
Arachnid mesh
2x SoJ
Amulet +3 summoning skills +9x / 100 life or Mara if you can't afford the magic amulet
Switch: CtA + Lidless
Grand charms with +1 to summoning skills and 12 fhr (to catch the 26% or 39% bp)
Annihilus
Resist lightning / fire small charms to max the resists to those elements in hell
Might merc (= more damage on your skeletons)
And you = pwnage.
Remember: for a summoning necro, Enigma > Bramble cuz you can get total control of your minions.
