okay I finally found a map online that helped me. I didn't know they supplied you with a ship and boat at this part, because the last time I beat the game I skipped these bonus bosses. Anyways, I got through em, the Whisperwind Cove was the worst, because of how lengthy it was, and I wasn't able to beat Deathgaze, he owned me bad. I beat every other bonus boss though, in every dungeon, and then went on to beat Chaos again. At any rate, I'm pretty contempt with the outcome of this run through, because I got a lot more done than last time.
