heres a new idea i haven't seen yet. A poison/summon necro. The basic stats could be as follows:
max skeleton raise
max skeleton mastery
max skeletal mage
1 into other summon trees
rest stats into poison dagger,
poison explosion and poison nova.

There, a basic concept. Any suggestions to fine tune this necro? I'm testing it out right now, and is a pretty good pvm, but i haven't done pvp yet. I would appreciate some assistance if you see a where a change is needed

I had a poison/summon necro back in the day when I was still poor lol. They are a fun build:

Max Poison nova
Max 2 synergies for poison nova
1 corpse explosion, don't bother with poison explosion
Max Skele mastery
3 Raise skeleton
3 Raise Skele mage
1 point into all skills in the summoning tree, except for Fire Golem
Iron Golem > Fire Golem

The rest of the points you should probably dump into Raise Skeleton.
Any equipment with +skills is fine. If you are poor, Trang's set is a good option. Death's Web would be a nice weapon for this build. Make sure that you use Trang's Gloves, at least, it has sexy extra poison dam.

you can just max skele, summon resist skele mastery and the rest into Nova. but it will be sorta weak

thx for the help, i have a good idea of what i'm doing. Thanks again
