(Translations) Octopath Cotc JP Aoi EX3 in 7 Turns

Team Overview 0:00
Battle Start 4:44
Break 10:36

Important info about the Aoi fight:
1. The EX refights are different from the non EX fights including the fight to unlock her.
2. It is possible to turtle the EX2 clear for 6 star, I did that before I could speed clear. This video shows how    • 【オクトラ大陸の覇者】アオイEX2 耐久編成 ※夜戦闘のみ  
3. This fight is very hard! EX 3 has around 70 million HP and EX2 has around 50 million. Don't get discouraged if you can't get it immediately. It took me 6 months since release to do EX3, with somewhere around 50 hours during that time solely figuring out the fight.
4. Without Shana, do not let Aoi attack after her style shift, but don't break before she shifts. This is the only was to keep the incoming damage manageable. I recommend Cecil as a tank if you aren't using Shana for her EX Skill and hit as many shields as possible. Follow up attacks like the first EX Erica and EX Hikari are very useful as she still dodges. Remember there is only 2-3 turns to break her before she style shifts.
5. Even turns she dodges Physical attack and odd Elemental attacks

Details on this video:
It is important that Shana is fast enough to use the EX skill before death
EX Osvald needs to be slower than Relm, EX Pardis and Osvald, but faster than Neha

Turn 1:
Pet use to charge Neha's ult meter
Setzer's EX Skill needs to be used at some point, so now is a good time
EX Pardis uses a 5 hit because there isn't really anything else to do in this pair on turn 1 and the shields are nice
EX Osvald gives damage cap up for similar reasons
Neha needs to use a prayer to lower SP for the passive

Turn 2:
Shana's EX Skill is needed to survive, so using it on turn 2 and 3 makes it last until turn 5
Relm needs paint, this skill combined with the EX Skill gives perm primary colors
Osvald hits shields
EX Osvald needs to hit his ult for the deep grudge and EX Rondo needs the turns later, so now is the best time

Turn 3:
Shana EX Skill to extend unsinkable
Relm EX Skill's condition is turn 3 or later, so this turn is the earliest as it needs to be used
EX Osvald gives Relm 100% Potency up until turn 7, so this is the earliest turn to do it
Setzer gives fire and dark weaknesses to get the 10,000 damage cap up with 7 or more weakness count

Turn 4:
Relm uses ult for a precise amount of shields
Osvald uses ult this turn because he can't use it next turn, so using it now is better than not using it at all
EX Pardis EX Skill needs to be used, so this is the first opportunity to use it; it also gives Neha the perfect amount of SP
EX Osvald gives damage buffs because it's better to use EX Rondo later

At the end of this turn, if Aoi has less than 10 shields she goes into boost mode on turn 6 instead of gaining shields and only taking damage from crits. The problem with this is the boost attack gives parameters down to front and back. Parameters down halves the cap of stat buffs. i.e. if Relm normally has 50% Elem atk up, with Parameters down it would be 25%

Turn 5:
Crow pet gives EX Pardis 10% Elem atk up for the first turn of break
EX Pardis ult the turn before for 150% Potency up and 100,000 damage cap up
EX Rondo EX Skill for water wave to last the whole break
Osvald EX Skill for a massive 30% Elem def and res down; this action is the only reason the damage is enough as before I learned this was possible I was always off by around 5 million
Neha EX Skill for damage cap up, also the main reason for a turn 7 clear instead of a turn 6 clear

Turn 6:
Chomper pet gives a massive 30% damage increase
EX Rondo needs to give guaranteed crit and hits good shields
Neha ult is a massive damage boost and Relm hits a lot of shields
Osvald breaks and does good damage with his last turn of potency up
EX Pardis does a lot of damage

Turn 7:
Pet gives 10% Elem def down
EX Rondo ult is important to give 15% ult Elem def down
Everyone else does as much damage as possible

This only had around 1 million overkill
