Build for the new Primeval Kings' Tomb area

Hey everyone! Here's just a build that did me well in the new Underworld PvE area. I have 10 points in every Necro attribute line, but obviously you can change it up if you want (it focuses primarily on Curses). This setup expects that there'll be at least one tank around dealing damage.

1) Vampiric Gaze - I always have this spell on for the instant heals.
2) Faintheartedness - Useful in both helping out warriors and keeping any monsters attacking you at bay.
3) Mark of Pain - This skill is either useless or the best thing on my skillbar, depending on how the enemies are acting. Usually, it's a good one (especially if you pile Spiteful Spirit on top of it), and I like to cast it on the biggest creature there (assuming a big monster will be prone to touching other monsters).
4) Soul Barbs - This is extra-useful if you have a Mesmer in your group.
5) Dark Fury - A health-sacrifice, but Vampiric Gaze usually evens it out well enough. Again, I use this to aid Warriors.
6) Troll Unguent - A Ranger skill I frequently use. Your healing skill may vary.
7) Spiteful Spirit - Everybody's favorite!
8) Rez Sig - Because you don't want your friends to die. At least, not when you aren't using Death magic.

In order to get the most out of this build, I use the Idol given to you by Cinder Linnwood out NE of Elona Reach (Diviner's Ascent), which increases cast and recharge time of Curses.

Enjoy!

Since you are using Spiteful spirit i will reply with the assumption that that is the basis of your build. When playing a SS necro (spiteful spirit) it is assumed that you are there to deal damage and lots of it. In order to acomplish this it is imperative you have rank 16 curses. In addition it is assumed a SS necro will bring Arcane Echo a memsmer skill in order to cast 4 spiteful spirits in 20 seconds.

The only reason why you are N/R atm is for troll unguent, imo troll is useless as your teams monks should be doing the healing. Remember your role is Damage focus on that. So let me comment on every aspect of your build

Vampiric Gaze - Drop this... again let your monks heal if you. If you want a nuke for mobs use Desecrate Enchants which is superior to vamp gaze (in hoh uw) as it is aoe and is a curse spell.
Feinthardedness - not a bad anti mele spell however Enfeeble works better in HOH as it is cheaper recharges faster and reduces damage by grasping darkneses significantly. Great to cast if one runs past ur tank(s)
Mark of pain - can stay as it can be devastating with minons or war/rangers
Soul barbs - a decent curse however takes a focused build to really take advantage of it imo is unnecessary in HOH UW. Drop this and take Arcane Echo for use with SS.
Dark fury. Drop this immediately! Your warriors dont need adrenaline there purpose is tanking not dealing damage and they will be almost permanently blind in HOH uw so wont have much adren anyway.
Troll unguent - Drop this you need to be N/ME. Imo troll is useless as your teams monks should be doing the healing. Remember your role is Damage focus on that. Replace this with Spinal shivers for interupting of dryads/wurms etc. OR take blood ritual with a slight investment in blood to occasionaly support your monks with energy.
Spiteful spirit - Keep this or die!
Res sig - keep it duh

here is your cookie cutter SS necro build

SS
Arcane echo
desecrate enchants
mark of pain
res sig
blood ritual/shivers
Enfeeble
mantra concentration/resolve (many interupts in hoh uw and you have long cast times) put remain points into insp and use one of these for interups

all points in curses
high soul reaping
mabey some in blood for ritual
rest in inspiration for mantra
And get urself a Vilnars staff.. there fairly cheap
