- Glacial Colossus can be replace if there is another necromancer in group using it or if tank is running a major vulnerability set like Turning Tide and/or Archdruid Devyric. Ice Comet is a good replacement for bosses and Elemental Rage is good for trash pulls.
Rotation:
First rule for necromancer is to make sure blastbones is always active. It is our hardest hitting ability making it the bread and butter of the necromancer. It's has a 2.5 sec arming period and if your close to your targets a .5 second exploding period. So you should be able to cast 2 skills before recasting blastbones if your fast enough. Also try to make sure you are on your front bar when blastbones pops so get max damage with it. Not a big deal if it goes off on your back bar.
