I restarted recently after having taken a timeout for aprox 6 years or so, I have always enjoyed playing a necromancer even though I have had other classes, took a necromancer again as it is a highly versitaile class.

For where to go, even though I restarted, little over a month ago, those levels went so fast so I cant remember exactly where I went, but there is a Vah'shir standing near the soulbinder in PoK, that hands out armor quests in your level and there is also the hotzone dude near the guildhall entrance which gives you a hint where to go.

Best site for necro-questions I have found which is alot more active than here, is http://www.necrotalk.com/

Zerthimon Iksar Necro - Antonius Bayle

It has been several years for me, but if i recall correctly i did my thirties in the Overthere. Big zone and plenty of mobs of different levels in different parts of the zone. Course, the zones in Serpent Spine are also big and offer plenty of kiting spots, but I am not familiar with which one would be best.

You just need plenty of room, and use your clinging darkness line of spells to snare-dot the mob to slow it down. Make sure not to let that run out, refresh it if you need to. Just stay ahead of the mob and you will be fine. Also, don't send your pet until you have several dots going and they have all ticked at least once or twice, so your pet can't gank aggro from you and get killed. Since you will be moveing the mob at all times, the best pet for this is a rogue for the backstabbing (check alla to see which one is rogue at that level).

The key for kiting is aggro control - it has to be on you at all times. If you do have friends nuking or plinking arrows while you run the mob around, make sure they don't join in until the mob is down to 90% so you can establish yourself at the top of the hate list. You want to be in control.

Necros are a great class, just experiment to find your style. Happy hunting!
