The chances of anyone under level 30 making it in there with invis
on a full spawn are slim to none. Whilst the goblin sage, and the
goblin patriarch may be able to see invis. So do some mendicants,
most prelates, and all priests. A few evokers have also jumped me
while invis. It all depends on your level versus the mob level
when it comes down to it. Sometimes L19 priests see me and attack
me, sometimes they dont. Those goblins will agro on almost anything
including L50 players.

You've got to pass a lot of goblins to get to the throne room.
When the dungeon has a good few people in it, and it's nice and
clear, you could probably sail through without incident. I would
assume all goblins can see you until you con each one otherwise.
Because once you walk by one scowling goblin, they all jump in.

Permafrost green casters can kill. I will not, to this day,
walk around freely in there since you never know what may
happen. One priest and two evokers for a melee class is
instant death. I'm not trying to scare people from going in
there, it's just I have an extremely large amount of permafrost
experience - and getting lucky sometimes gives people the false
pretense that you can stroll in and own a particular place.

Harmonic, L14 - L24 in permafrost, most times died in this dungeon.
