Caina Walkthrough

List of Bosses in Caina

Caina Guardian Bosses

Harem and Natural Dancer

Metis and Akihiko are useful for this fight since Metis can target the Natural Dancer's Ice Weakness while all of Akihiko's Attacks all deal neutral damage into the Harem Dancer. They're also both Strike-type attackers, which isn't resisted by either enemy.

Harmony Giant and the Judgement Sword

Even though Yukari specializes in Wind, you'll want to bring Ken instead as your main support to avoid Yukari getting beat down by the Harmony Giant's Electric attacks. If you need an extra Wind attacker, you can always bring Metis with Garula as one of your other party members.

Caina Monad Bosses

Chaos Cyclops

Chaos Cyclops is one of the Monad Bosses found inside Caina. This boss is relatively easy as long as you don't bring anyone weak to Fire and Ice attacks and you remove his Defense buffs.

Eternal Eagle

Eternal Eagle is another Monad Boss found inside Caina. It will be accompanied by two Jealous Cupids that like to Charm your allies, so make sure to deal with them first.

Tips and Tricks for Exploring Caina

Party Member Ranking

Rank	Character	Explanation
1	Ken	On top the usual Kouga, Arrow Rain, and Mahamaon, Ken will gain access to Mediarama making him an amazing all-rounder. His characteristic on top of the limited resources is still amazing for quickly building up his Theurgy Gauge.
2	Mitsuru	May seem lackluster at first but will be amazing once you get her Characteristic at B8 which increases party's chance to Crit when under any Status Conditions.
3	Yukari	Still the mainstay main healer but Ken does overshadow her since he also has Pierce attacks. Almost a necessity for the second Guardian Boss if not for Metis.
4	Metis	Best character to handle the bosses in Caina but doesn't perform that well against the regular enemies.
5	Akihiko	Raises in useability thanks to finally getting access to Ma-Kaja skills on Aigis and getting his first characteristing back in Cocytus. Not useful against the last boss but fares pretty well agaiinst the Regular Enemies.
6	Junpei	A bit lower than Koromaru initially but is an amazing choice once you get Mitsuru's Characteristic which increases party's Critical chance when attacking enemies under status.
7	Koromaru	Falls off quite a bit since a lot of the enemies here resist Fire or Dark but still a decent choice against the Harmony Giant and Judgment Sword.

Keep Saving Your Twilight Fragments

After beating the bosses in B9, you will have access to locked chests that need one Twilight Fragment. Two of these contain the items for Mitsuru's, Yukari's, Koromaru's, and Ken's Linked Episodes, so make sure to allot 4 Twilight Fragments for these.

Obtain Metis' Second Theurgy and Upgrade Fuuka's Oracle

After finishing Caina, you can unlock new Theurgies with Metis' Charging Blitz and upgrade Fuuka's Oracle to Revelation.

Metis' is just the same as Aigis' Maximum Firepower but deals Strike damage instead meanwhile Fuuka's being great in a pinch like fully restoring HP and SP.
