necromancer

i cant find a up to date skill tree build but i would like to play as a classical Diablo 2 ish necro if anyone can help me that would be awesome thanks.

This is using a witch to start but templar would be pretty similar. http://www.pathofexile.com/passive-skill-tree/AAAAAgMABkkHYwj0DlwQdBCXEZYTbBVQFm8XLxmFGYoabBqPHNwdqh6UJDwkqiSwJ6ko-iqYL28xiDbpPI5EBEV-RZ1GcU25VcZV1lYtVytXyVptZOdqrGvbbRlvnnC7c1N5A3qqfRh-WX_GgKSCHoLHgwmFYIbRiECLeo9GkDOTJ5rgm6GbtZ2uoqOmrKcIpyunXKrErD-sf7QMuJO_l8BUwfPDOsk9ykrMvM9l0NDT-9kL2RPa3dsL3FfhiONq6rrr7uyK8XbyHvPd9tr31_no-oD60vsJ
This is the end build though. I was specced into Minion instability while leveling to use my skeletons and zombies as bombs.
I didn't take Eldrich Battery until I got a Cloak of Defiance for my summoner.
Skeletons were used as cannon fodder for a long while. I stopped using them when my zombies could handle the majority of enemies. You can self cast or put them on a totem.
Queen's Decree was useful while leveling up for more bodies. I switches to a 1H plus shield, again, once my zombies become strong enough.
Bones of Ullr I used the whole time. It's pretty useful because of the added minions.
For spectres I just picked any ranged unit until merciless act 3 where I sought out specific monsters (flame sentinels were my personal favorite, the evangelists are pretty good but they lost some utility with the recentish nerf).

Links
Zombies: Raise Zombie + multistrike + faster attacks + melee splash (end game) starting out I slapped on minion life, minion damage, and anything else to make the live longer
Spectres: This really depends on what your monster of choice is. You wanna make that minion do more damage with supports that have the "more" damage. for my flame sentinels I used: raise specter + Conc. effeect + faster Casting + LMP + Fire Pen

Skeletons was similar to zombies early on. Minion life, minion damage, what ever else for more damage.

Auras: it's really up to you what you want. Just try to have auras that benefit both you and your minions.

Other: having curses or an attack can be useful. I went for arc with culling.
