Inspired by Pyth, i created a necro build which is concentrated on grouping fiends and area damage.
FARMING = Solo, no henchies. Eventually your guild members for paying the guild hall.
Where to farm?
If you're not yet used to it, begin with weak fiends.
These special farming areas everyone talks about will soon be "nerfed".
Better walk around same areas, when you're in the right place, redo the area again and again.
TIP: Don't tell anyone your farming place, so ANet can't "nerf" it
16 Death magic
12 Blood Magic
9 Soul Reaping
I'm not a friend of telling you exactly which skills use, just the basic ones described below.
I didn't involve my 2nd prof. monk skills at all (at first I thought of healing my minions w/ monk prayers, but "veratas sacrifice" does that pretty well.
The most difficult part on this builds farming is killing the first fiend (w/o minions...).
Use Deathly Swarm (if it's more than 1) or Vampiric Gaze to keep yourself alive.
Cast Animate Bone Minions afterwards (1 corps = 2 minions).
For now, with your 2-4 lil friends, head over to the next group of fiends.
Don't forget to always cast Veratas Sacrifice (i mean ALWAYS!)
To initiate a battle, cast Deathly Swarm (some damage to 3 fiends).
With Death Nova on all your minions, blast half of them using Taste Of Death, spending you lots of health and damaging (105dmg) and poisoning (12 sec.) the surrounding enemies.
As soon as an enemy falls, spawn more minions.
Spawn and Kill until there's no fiend left.
Then hurry to the next group of monsters.
When you have lot's of minions, forget to cast Death Nova on them, because it's hard to see which one to blow up (as Taste Of Death doesn't automatically blast the "deathnova" minions)
-They take the damage instead of you
-They give you energy (soul reaping) when they die
-They damage the fiends (death nova)
It should be quite easy to kill the hords of fiends.
And spawn as many minions as you can!!!
i usually run around with about 30-40.
just don't worry when they die (they run out of life sometime, can't prevent that).
Other skills that can be useful:
Well Of Suffering - As the fiends are usually all together, this well will drain all of them by 5hp/sec, should help you getting them down in less time.
Offering Of Blood - I use it only when all the fiends are dead and i still have to spawn some minions. I usually run out of energy in this situation, this works fine for me. Elite Skill
Putrid Explosion - I cast that either when i have LOTS of minions or when there are none and the fiends begin to attack me. That safed my live several times.
That's it, let me know if you disagree with anything or if you can improve something.
Make lots of $$$.
(I make about 2k/10min-run)
