Necro Equipment Progression?

[Taiku]

So I've been loving my necromancer, currently following the 6-minute bard diet guide and I'm on my first bard, already leveled to 15 thanks to the xp bonus we're getting, it would be faster elsewhere but i can set my own pace here, and afk a lot when I need to.

My question is what would my next piece of gear be, Currently have 2x 55 hp rings and an robe of the the oracle, Are there any like.. needed pieces of gear that I should pick up? I could see how a bigger mana pool would help right now because when I get a lot of resists, I end up too OOM to do anything but just tank while what DoTs I have on the mob and my pet kill it.

Jboots came to mind, when can I camp those or is it so overcamped that I should just save up to purchase them? Should I be aiming for any other items in particular? I'm doing pretty okay in the gear I'm in but more mana wouldn't hurt. SoW potions are kind of a pain x.x I don't really want to carry a bunch around and never want to use them, I'm one of those gamers who will get grenades or big buff potions/one time stat increase items and save them forever because I don't know when I'll actually need them :x
