If this quest is bugged for you, just join a random questing group in Azure Span in the Group Finder, and it should work. Much easier/faster than switching to/from Warmode.

Description
Now we should be able to face the Spirits. Did Ruriq fail to mention it? By our tribe's traditions, we must face the Spirits in combat before asking a boon of them. The strength of their blessing is dependent on how well you impress them. Perhaps that is why the Gleamfisher insisted we all work together. If you take on Kraunot, the Spirit of Air, Ruriq and I will tackle Otu'rorq, the Spirit of Water. They dwell in the cave behind the nearby waterfall. We will meet you there, adventurer.
