Managed to master Phoenix and Manticore though neither was particularly clean. Tried Hecatoncheir but just didn't have the damage to push through. Pulled with one of the free tickets on the Wind banner and got Zack's awakening so that should help next time. Hecatoncheir seemed to have pretty low damage output so I think with some extra DPS he should go down ok.

Am a couple of rat tails short of putting my fifth crystal to 65 so I haven't unlocked the next book yet. Guess it'll need to wait until after the Cardia mission reset. Still have one realm/elemental ticket banked that I guess I'll wait to see what I need help with on.
