Who doesn't want their own Blood Fiend? The class "feeds on death and decay," and they enter a 'Death Shroud' form if killed to keep fighting.
They have their very own unique set of character skills called Wells, Minions, Marks and Fear. They can support allies and debuff enemies alongside summoning minions to do their bidding, and of course strike terror into foes sending them running off.
"Death Shroud is a special ability--usable by a necromancer at any time--that utilizes his life force as a secondary health bar. Instead of entering a downed state when his health is reduced to zero, a necromancer automatically activates the Death Shroud ability and assumes a spectral form," the official Guild Wars 2 website.
Cool beans. Guild Wars 2 releases exclusively on PC and will be free-to-play like its predecessor. See the clip below for a compilation of the necromancer's skills.
