Necro: what am I doing wrong?

[necrosaurio]

I've got a level 5 Iksar necro and I can't manage to kill any yellow mobs. White mobs are more or less OK, but they leave me at less then 40% HP and no mana. Dark blue mobs take 10000 kills to get a single yellow. OK, I'm exagerating about the dark blue but not by much :P

My normal routine is:
- Get a pet out
- Give the pet a weapon (dropped from the skellies) and, if I have it, a shield
- Buff myself with minor shielding + grim aura
- Aggro a mob with whatever spell
- Darkness + poison bolt the mob
- Fear

Most of the times, the mob interrupts my casting and resist fear so often that I end up tanking and, most often, have to turn and run.

My equipment is all cloth and I haven't got a shield (haven't been able to find a necro one around) but, supposedly, necros are "easy". I have a lot less trouble kiting with my bard, although it also feels less interesting.

What am I doing wrong?

Even if I manage to kill the mob, I have to sit and meditate to full again. Is this normal?
