Skullrot Teleportation Errata?

[Gold Katana]

Under Skullrot Special Spell Effects: "In addition, Skullrot is protected by the equivalent of a dimensional lock spell. This effect bars ... teleport, greater teleport..."

Under Lriznisith's Tactics (Room 6): "If brought below 40 hit points and Slouva isn't here as well, he teleports to area 8..."

What's up? Is this errata or am I missing something?

Thanks. :)

Oops.
It's an error. Change Lriznisith's tactics so that instead of teleporting, he simply flees to area 8 to warn Slouva.
Good catch, Gold Katana!

Speaking of catches...

In Thirteen Cages, the bad guys have the ability to "gate" in a Glabrezu as back-up, even though the entire area is under lock down due to that dimensional lock... Did I miss something here?
