I tried zoning into Nurga on my level 1 monk and got evaced with the message:
You are not yet experienced enough to pass through an inter-planar portal.

So I tried getting level 2 and trying again and got the same message

I've seen people say the same thing about upper guk but I was able to bring a level 1 barbarian in there at the same time when the troll was having trouble.
