Ive noticed that Necromancer is the least played class so far. I dont see many running around, so I would like to start an officail necro post, and try to help people play the class more effectively. I am, by no means, a PRO necromancer, but I do have over 40 hours playing as one.
There are a couple of things you need to know about when playing the necro.
1) Your primary source of dps is conditions.
2) Your condition damage does not crit, so do not collect gear that grants precision(crit%). You want to focus on Condition damage.
3) Learn how to use combo fields and combo finishers. If you dont understand combos, please read below.
A) Some abilities have an attribute, "Combo Field: Poison" for example. See here:
http://wiki.guildwars2.com/wiki/Chilblains. This is a spell that you place on the ground and people can stand in it or shoot through with a combo finisher to trigger the "Poison" effect.
B) Some abilities have and attribute, "Combo Finisher: Projectile" see here:
http://wiki.guildwars2.com/wiki/Necrotic_Grasp. This is an ability that will allow you to benifit from a combo field.
C) Remember, not all wep combos, have combo fields and finishers. You may be using a combo that has neither, so you might need to pick one up from your utility skills. And remember only combo finishers can trigger combo field effects, So dont be alarmed if your abilities do nothing when shooting in or around a combo field.
D) So a typical Necro combo would be, use chilibans on the ground, wait for an enemy to trigger the trap, once he does, shoot a Necrotic Grasp through the poison cloud it leaves behind ~ and it will grant the projectile the poison attribute. This will up your dps on the target. And remember, your friends can shoot threir own combo finishers through the cloud too and gain the buff. Communication with your team is super important if you want that edge in DPS, especially in sPvP, where everyones gear is the same.
So, I have been testing out a lot of builds, but one thing is constant in PvP and PvE: The Staff. I use the staff because it has the necros only combo finisher. (There may be a utility or ultimate that has one, but I have not unlocked yet.) The necrotic grasp. This skill is your Staffs auto attack, so its great for hitting combo fields out in the thick of battle. To be honest, sometimes you will hit a combo field and not even mean to. Thats the beauty of this ability. Its spamable and it has the potential to be powerful.
So, In PvP, I use the following wep combo. Staff swapped to Axe + Dagger. This gives me the slows and damage to deal some great damage to people.
For my utilities
#6 Well of Blood (Has a nice combo field, plus a nice AoE HoT)
#7 Spectral Grasp (This pulls an enemy towards me, similar to DK in WoW)
#8 Spectral Wall (This gives a 33% damage reduction to all allies that run through it, adds a condition of vulnerable to enemies that walk through it, Plus it has a nice combo field)
#9 Spectral Armor (This is another 33% damage reduction, and it regens life force when hit.)
#0 Summon Flesh Golem. This guy hits for a massive amount with his charge.
My priority when PvPing, is to get my traps out and then switch to axe dagger to DPS, periodically switching back to my staff to place more traps and use combo fields with my finisher. Once I begin to take damage, I pop my shadow form (Its great because the life force is now my HP). Once I exit shadow form, and the enemies are not dead, I will use my spectral armor to gain more life force quickly as they hit me. Then I can pop my shadow form again. If Im taking massive amounts of damage, I will cast my spectral wall and get the buff from that, before returning to shadow form. This gives me a bunch of damage mitigation.
I like to use the charge ability on my Golem too, but you dont want to waste it, because it can hit multiple targets in a line. Its usually a good idea to wait for your enemies to get in a position where the golem can charge through 2 or more, to max your dps.
If you guys have anything to add, or a better build, id like to see it and try it out.
