Glyph of Sacrifice
-- Rez Sig / Cap Sig
Ran my ele with a full hench group from Maatu Keep to fort aspenwood / jade quarry on both kurzick and luxon in around two and a half hours using this build. Precast attunement, cast sacrifice, drop meteory shower, run to engage target, cast promise when they get low, then hit flame burst+inferno+flame burst. When they die, recast glyph, cast meteor shower on a new target. Rinse and repeat. Use dark escape to tank just long enough to kill everything.
Enjoy, but watch your exhaustion... while you can generally cast a meteor shower every 10 seconds or so, its a good idea to throttle it just a touch, so that you dont over exhaust yourself. With a +5 insightful I had 75 energy running this... there was times when I had ~40 points of exhaustion on me.
[it takes 30 seconds for 10 points of exhaustion (one spell) to go away]
