Necro gear suggestions

[Labatt]

I'm looking for suggestions as to what piece(s) of gear I should get or save up for for my level 20 necro. Currently have 500p to spend and the following pieces already:

Flowing black robe
Golden jade bracelets x2
Moonstone rings x2
Dagger of marnek
Stein of moggok
Alligator tooth earring x2

This is my highest char so I can't farm anything on a different character. I really have no issues with mana because of lich spells so should I save for something utilitarian like CoS or JBoots? Or buy some hp gear? Any expert necro advice would be appreciated, never played one before but I'm having a blast.
