Necromancer Epic - Question About PoSky

[LenkoCambria]

I don't know when he depops, but I do know that we've gone up to do Sky and he has been up (with no other people in zone, so he'd been up for a while).

You can easily invis past the Island 2 mobs if you have a key to 3, but if not, you can head up to Sky with a cleric and another necro, have the keyed necro head up to Island 3 and summon your corpse.
