Start this quest line by talking to Boddly in Goldpaw Library. Quest 176 is the beggining. Then quests 177-183 are all linked.

Quest 178- Complete 60 side quests.
Quest 179 - Recruit Grabe the Glowering (Fire Elemental), Mumbian the Mover (Water Elemental), Calooh the Carabinier (Light Elemental), and Coronach the Cranky (Dark Elemental) and make them the active Higgledies in your party. Can make in Evermore.

Quest 181 - Defeat Mausinger (lvl 75)
Quest 182 - Clear the 30th floor of the Faraway Forest Maze Will also net you

Finally Defeat Zeta for quest 183. This fight was annoying. I went in at level 97 w/full Gold armor/accessories on my leader (Evan). Can get Gold equipment from giving 400+ orbs to boss chests in the labyrinth. Weapons all >500 attack. I found Ding Dong Discipline to be OP. Spam dodge and then depending on your upgrades you can get 6-10 combo attacks (X) before the combo finisher (Y) while time is slowed. Rinse and repeat.
