Stuff : rune of the thief (+precision +condition dmg) & crit jewel
Sigil of air (DD on crit) + sigil of earth (bleed on crit)
This way I have like 70% critical chance, which proc bleed twice from weapon + traits, and proc air sigil DD for around 1k dmg.
Blood is Power raise life force by 20% every 24sec (traited) + seal giving 1%/sec in combat.
Death shroud is a great defensive & offensive tool with this build whith enfeeble + death shiver each time I cast death shroud.
Update 30/08/2012 : can't link the build because it was a BWE2 one and all traits changed since then. A close build today would be something like that :
