There are two versions of Goxnok. The first one spawns after you turn-in the coin to the indifferent Tracker Azeal. This one is blue to a level 27 and is on Crusaders faction(presumably, he was amiably to my iksar and kos to the froglok shaman with me). After reaching the drachind spy's(this one was blue) spawn a new Goxnok spawns, this one is level 27 and will attack you when you engage the spider. Also be careful you'll be fighting them near where the ancient Jarsath wanders as well as many frogloks and drolvargs; so be prepared to loot and run.
