I take you on a walk about in Yolunakea along the fastest and most efficient path to obtain every knowledge outside of completing the main quest.  In previous dungeons you had to kill the last boss multiple times to accumulate the last seven or so knowledges to complete the second knowledge quest.  Yolunakea is the first dungeon where just by getting the knowledge in this video, and doing the quest-line solo, you'll be able to get all the knowledges for both the 70 and 130 stacks, as well as netting yourself a couple of Vaha earrings.  There is still knowledge to be gained from killing the last boss in Elvia, and through the scrolls he drops, but again these aren't needed to complete the knowledge quests.

Enjoy
