poison necro advice please

Making a poison necro(primarily pvm) current gear(opinions welcome as well)

Helm: shako/2 necro skill 20 fcr all res 50% poison reduce circlet
Wand: deathweb 5/5 poison facet/cta
Off hand: homunculus/spirit
Amulet: maras
Ring: soj/?
Belt: arachnid
Armor: enigma wirefleece
Gloves: trangs
Boots:marrowwalks
Inventory: anni/torch/poison skill gcs

Merc: Act 2.. nm offensive? defensive?

Wep: botd? Infinity?
Helm: andarials
Armor: fort

Skills: obviously max poison dagger,poison explosion, poison nova. Rest?

I'll need most curses, prereqs etc minus dim vision confuse and attract. Max skele and skele mastery? Or not worth it? Max corpse explosion? Or just 1 into clay golem and golem mastery?

Any tips/help appreciated.

What I would do for skill wise:
Obv max poison nova, dagger, and explosion.
1 point into teeth and corpse explosion for pre req
1 point into all needed curses, some hard points into lower resist until level 16, which would be -61 or -62 resistance. After that it’s not worth it.
2 options now:
Option 1: using Revive- 1 point into skele, mage, iron, blood, revive, golem mastery, summon resist, few points into clay (unless you want fire golem).
1 point into bone armor
Rest in bone wall for synergy
Option 2: no revive, would be 1 point into golem mastery and summon resist, few into clay (unless you want fire golem).

This is what I do anyways.
