Guild Wars 2

Silence:
Target is completely disabled for 15 seconds (no stun breaks, no skill use, nothing). Target becomes immune to any source of damage for those 15 seconds.

Alternative

GIVE ME SOME VIGOR – Why are we the ONLY class with NO access to vigor….

Sacrifice Minions
Sacrifice your minions and gain health for each one sacrificed in this way (3k each base and effected by healing power).
Cd; 120 seconds

Would be cool to allow a tanky necro to have a 12k elite heal available.

Well of Dhuum

For 20 seconds, you create a well that’s twice as big as normal. No foes caught in it can be resurrected. If 10 targets dies or is already dead in it, friends or foe, you summon Dhuum to fight for you for 60 seconds.
