Guild Wars 2

Came up with a fun hybrid build for dungeons. Lots of sustain, decent support for a nec, and can stack 16 might in a couple of seconds and maintain 25 stacks fairly easily.

Traits:
Spite: Spiteful Renewal / Unholy Fervor / Signets of Suffering
Curses: Plague Sending / Master of Corruption / Parasitic Contagion
Blood: Blood Bond / Vampiric Presence / Transfusion

Weapons:
Axe and dagger / dagger and warhorn

Armor and accessories: Combination zerk, rabid, cavaliers so that power is around 2000, condi is around 800-900, and crit chance is around 30-40%.

Runes: Antitoxin
Sigils: your preference

Utilities: Signet of Vampirism, Plague signet, Blood is Power, Epidemic, Plague

So the nice combo is:
1. Blood is Power: 8 might, 2 stacks of bleed on target and on self, plus 2 stacks of torment on self, which triggers 5 might on self from antitoxin runes = 13 might.
2. Deathly swarm: transfer your 2 bleed (and torment) on target. This triggers blood bond, which gives another 3 might stacks = 16 might total.

For mobs, drop enfeebling blood then use epidemic. The healing from Parasitic Contagion will be very good.

Support includes drawing condis from from Plague signet, might sharing from Blood is Power, aoe blind from Plague, some burst and healing from frequent Blood Bond proc and Signet of Vampirism, and some healing from transfusion.
