The hardest part about this fight is the adds that spawn at each 20% interval. The first set of adds (16 ^^^ elementals) spawn at 80%, they are all one encounter and grouped. The next set at 60% spawns 3 Epic x2 golems, all in one encounter. The 40% adds spawn as three sets of three Epic x2 Giants, nine total. The last set of adds at 20% are three x2 behemoths.

Vox herself does not have much HP, the adds are the 'actual' encounter and difficulty for the fight.

As of 15/09/13 Vox was changed so that her spawned adds could not be run around.
