Ciela (boss)

The manifestation of the Planet's Consensus of Wills, having at its core the three Wills of Origins: Horus, Clyuue and Juklizda, this will be your "opponent" during the final battle in Ar tonelico Qoga: Knell of Ar Ciel. However, and unlike the other bosses, your role in this battle is convincing Her that humans still deserve a chance and persuade Her into accepting the Heart of the Land the party brought for the sake of restoring Ar Ciel. This battle is subdivided into four phases, each of which has a different pair of background music and battlefield, as you can see listed below: As you can see, each phase also represents one of the Planet's emotional states: respectively, they are hatred, grief, confusion and forgiveness. Now, for the battle itself, Ciela will be surrounded by three shields and will have a trio of souped-up Doll Model HBL-S Antibodies accompanying her, but unlike other opponents, you can't attack her with your Vanguards: if you try even approaching her, she will blast you with a shockwave that will send you back to the other extreme of the battlefield, and if you attack her, you will get hit with a reflect wave that will reduce the HP of all your Vanguards in an 80%, while additionally, she screams at you with an horrible static-filled voice phrases like "It hurts..." or "Die already"; which also cuts off the background music. Likewise, the Ultra Supermoves are disabled in this battle.
 * Phase 1: Battlefield: Ruins; Music: QoGa
 * Phase 2: Battlefield: Dead Land; Music: Au GuMu
 * Phase 3: Battlefield: Sea; Music: Ec Tisia ~Tarifa~ (corrupted version)
 * Phase 4: Battlefiedl: Green Lands; Music: Ec Tisia ~Tarifa~

Therefore, the only way to actually make progress in this battle is using Song Magic, which will be the same one the Reyvateils used for the final battle with Ar Ru. Each time you use the Song Magic in Ciela, you will get an special animation played, and keeping in theme with the reason for the battle, no damage markers will pop up. However, while logic would dictate that using the Flipsphere would be much faster, it also breaks the theme of the battle for two reasons: first, it doesn't play the animation you get when you use Song Magic normally, and second, the damage markers do pop up when using it, so it's better to just use the Lv. 4 Purge Songs. And while it's indeed possible to damage Her using attack items, that doesn't only go against the battle's theme but it's also a terrible idea given Ciela's resistances and defense, so don't bother.

So the entire length of the battle will be protecting your Reyvateil from the Antibodies and using them to rack up Beat Ups to Purge your Reyvateil, all while you continually keep yourself alive; as Ciela will also occasionally attack by sending waves and blasts that reach directly their targets, which can also inflict all status ailments and lower defenses. Don't really worry about killing the Antibodies, as anyway Ciela will revive them whenever they fall or the next phase of the battle begins. And while it's an extremely rare occurrence for Her to use it, Ciela also has an Stored Attack called Tears of the Planet, which launches enormous torrents of energy to your party to then finish them off with a gigantic energy sword, so if you're either lucky or unfortunate enough to see it, and since it's impossible to interrupt it, it'll cause extreme damage to your party and might outright kill them all, so be very careful.

Keep on mind that Ciela's stats will raise and Her resistances will change with every phase, although the shields surrounding Her will vanish one by one whenever that happens, showing the party is indeed convincing Her. It'll be a very long and tiring fight, but if you can stay alive for all the four phases and launch Songs with enough Burst, you will certainly convey the feelings of all mankind to Ciela, and reach a happy ending for all of the Ar tonelico trilogy. The approximate Burst values you will need are 100000~200000% in Easy, 250000~400000% in Normal, and 500000~650000% in Hard.
