Blood necromancer?

What kind of build build I need to be an offencive blood necrom I can only really find support builds.

Sounds like you're asking for a build.

No, I'm asking if It's possible, and if there are maybe a few key skill I would need.

Also another thing, Contagion and Tainted flesh both seems like good ways to spread disease, which would be more effective?

Well aside from the life-stealing skills Blood IS the utility/support tree for a necromancer.

So if you insist on being only Blood and you don't want to do support you will have to use all the life-stealing skills

Ok, thanks.
Is thanks.

Another question, is it only dissease that is contagious?

Yes, and disease will only spread among creatures of the same species.

Ok, thankyou.

You would probably be better off doing something with Death Magic or Curses, if you want to be an offensive character. Some attribute lines are more suited to offense than others.

Yeah, I decided to do curses, DM, and SR. I'm gonna spread conditions and start health degen.
