30/10/0/30/0 Ground targeted wells with siphon on them. 30 in to Spite for Close to Death and you can use the Flesh Golem with 30% increased attack. It is not going to be a max dps build, but it will work for what you seem to be wanting. I run this sometimes and it works well. Your wells chew through mobs and you generate plenty of health from it.
Dps is not a big worry for my necro. I want to destroy the enemy slowly.
What armour would you recommend.
If you feel comfortable with active movement and can manage DS to absorb attacks, you can just go zerker for the most damage. But if you think you want some padding there and don’t mind killing a bit slower you can go Valkyrie (more HP) or Knight’s (more Toughness)… or mix it up a little. Nothing says you have to go one stat combo on every piece of gear.
