Been basically farming these on test for all my various toons and anyone who wants to get a TA for free mask. I used a 91 mage.
Some of this has been said before but i know some people (like me) don't read every single posting before attempting things, so i feel it's worth reiterating.
Whoever requests the task must have completes the first quest, given by Elba Straw who sits on a bench next to small bank in pok.
Your group can shroud down to 55 for this version of the quest. You must have three people in group to request the task (mercs do count). Once everyone has the task, you can un-shroud and at least one person must head to permafrost keep.
You will zone into the regular version of permafrost, then move forward a short distance and zone again, into the instanced version. If you are not invis before this second zone in, you will be attacked the moment you enter the instanced permafrost.
The first three cages are all located right there in front of you when you zone in. The only thing that sees invis is the named you have to kill and hes guarding the forth cage (with santug) which is located in Vox.s lair. The goblins do not assist the cages, pets will attack the cages but they are seemingly immune to melee damage. Ironically enough, the only spells that reliably landed on an ice cage, were druid cold based spells.. Poison dots were resisted every time. Magic and fire based mage spells were hit and miss. I just equip pet with some summoned proccing weapons and send him in to whack on the cages.
So those first three cages are quite trivial if u have a pet handy.
Run to Vox's lair, there is the final cage to destroy as well as Freezkorr the large gobby u have to kill, along with about a dozen smaller goblins. If you need to, you can pick off some of the closer goblins without agroing the whole bunch, but once you go for Freezkor you are likely to agro 6 or 8 of them, so focus on burning him down and destroying the cage, keep in mind these little goblins are in the 55-60ish range, and hit very hard for their level. Once Freezkorr is down and the cage us destroyed then the task is complete and you can gate out. The mask appears in everyones inventory.
