Be careful when using the Gukta stone if you are KoS to the Frogloks. The book is VERY close to the camp.
Don't know why, but the very red, very KoS Froggy GM did not attack my Iksar, even though he was standing right next to the book. Guess I popped just far enough out of aggro range. Even so there are several tents with KoS NPCs nearby so watch where you step...
