My setup was pretty standard. When I was actively playing my summon necro he wore:

Helm: Shako
Amulet: Mara’s
Armor: Enigma
Weapon: wiz spike (need the fcr for teleing and CE)
Shield: Homunculus
Belt: Arach
Boots: Marrowwalk
Gloves: Trang
Rings: 2x Soj

Some of these items have since been distributed to my other characters (Mara’s, Sojs, Arachs, enigma). If I ever play him again I would go back to this setup.
