Lulu EX+3LBZack EX+3LBSerah EX+3LB500k102mzpro2https://youtu.be/9B7ZQecRgw8IfritIn my opinion this tier is the hardest so far but thanks to zack this is easier now (i had to take him from t4 just to win this), now for me don't waste lulu skills quickly... Do hp+ first for her buff to max it out and then go with her 2nd skill to enchant the party, if you do this exactly lulu now can go aoe, the reason i choose serah is the 2x prison and def down... Really helped a lot (she's also perdect cursed arts).
Serah EX+3LBCeles EX+3LBLulu EX+0LB477k112Jin Leehttps://youtu.be/RkLbswQ1e2EShivaSERAH AS HEALER! Ranged resist stage. Imperiler & Enchanters recommended. Tips in video description.
Onion Knight EX+3LBSerah EX+3LBLocke EX+3LB452k99Sidra_Gameshttps://youtu.be/qGf1WIz6mskShivaInitially did Seven, Zack, Yuri but decided that was too much power. This added at 15 turns, but now have lesser units locked
Golbez EX+3LBPenelo EX+3LBYuri EX+3LB506k100Jelis Whttps://youtu.be/gcm4arcZgc0BrothersNgl this is rough without a tank. Gotta be really really careful about taking breaks. There are two cuts in the vid. The first is because I was running it in-between classes and had to stop to go teach. The second is because I took a stupid break and died. In full disclosure, I did it twice. Be really, REALLY careful about taking breaks. Summon and bust the whathisname down before he can get that AoE hp attack off.
Eiko EX+3LBEdge EX+3LBGolbez EX+3LB503k105Gaanrohttps://www.youtube.com/watch?v=tmtbknVSZmgIfritVoice Commentary. I don't have to much strategy here. If anything, try to upkeep Edge's EX effect here as much as possible. Use a Brave+ if he's burning through his mirage buff too fast. Also, Space out Edge's Smoke Screens so you use 1 on the 1st wave, 2 on the 2nd, and 2 on the 4th. You should be able to survive the many HP attacks and delays thanks to evasion.

4 wave fight
MVP: Lulu EX+3LB
Beware of single target HP damage from Humbaba (wave 1) and Celestial (wave 5)
Penelo EX+3LBZack EX+3LBNone470k115Tequila7https://www.youtube.com/watch?v=Xfs7SOrEMGoIfritNo imperilers or enchanters built up & my Lulu has her 35CP only hence decided to use this lineup.
Have Zack keep taunting the bosses while Penelo batteries the party.
I like to Intercession 1 boss and ignore it after since it cannot gain brv easily through hitting Zack.
Pop Ifrit summon on second wave and deal as much dmg possible.
Conserve abilities to maximise longevity.
Celes EX+3LBPenelo EX+3LBLulu EX+3LB581k94Batisathttps://youtu.be/Hgw469t6L9UShivaPretty straightforward with a tank, just dont die.
Lulu EX+3LBAranea EX+3LBIgnis EX+0LB680k82Ackitaruhttps://youtu.be/NRQRMSMquMoBrothers1 reset for the 2nd and last wave
Shantotto EX+3LBYuri EX+3LBGau EX+3LB444k93Daspharaohhttps://youtu.be/6Elwm_FR87YShivaCountless resets. All waves are hard. If you don't have Shantotto or Lulu you're sitting this one out until at least Twins EX+. Totto imperils, Yuri shaves and Gau keeps everyone alive with good Lifeshaver timing.

Golbez EX+3LBYuri EX+3LBOnion Knight EX+3LB437k100Ssvegettohttps://youtu.be/x6m-yuRcaEkShivaEach of them can imperal and enchant his own element, so use that to bypass the resistance. Also try not to get broken in certain situations or they will oneshot you.
Lulu EX+3LBPenelo EX+3LBYuri EX+3LB543k91Xcaliblur 1https://youtu.be/o7oI_mAk9ycShivaI find it's easier to focus down one boss at a time. You need some sort of enchanter/imperiller for wave 2
Celes EX+3LBOnion Knight EX+3LBRem EX+3LB581k93Aarolei/Leileehttps://youtu.be/NFOyW0UZoTkIfritTo deal with the color changing Behemoths in Wave 2 bring Elemental Users, Enchanter, or super battery to not waste too many turns. In final wave, kill Celestial before it uses the All BRV Atl + Split HP attack.

Aranea EX+3LBLulu EX+1LBVanille EX+3LB700k77Palladhttps://youtu.be/3D2ZMZD_lwgShiva Since youre' not bringing a healer make sure they always have Vanille debuff on so they attack don't 1 shot your characters. retried a lot of times
Vanille EX+3LBShantotto EX+3LBYuri EX+3LB451k99ScarletClairehttps://youtu.be/MYIcnM7hMtABrothersInitial Clear. Holy imperil used for most of the fights, though Wind and Dark was also great for Shantotto. Vanille used for survivability most of the time.

Sephiroth EX+3LBLulu EX+0LBZack EX+3LB491k96Red XIIIhttps://youtu.be/xOedWvpMBwgShivaBeware of the behemoth's hp attack when they recover from a break. The Tiamat has a big BRV/HP aoe attack that can make you miss the hp requirement so look out for that if you're not bringing a healer.
Lulu EX+3LBPenelo EX+3LBSephiroth EX+3LB608k86General Solidorhttps://youtu.be/7wJ6zbGT5oUShivaRanged Resist Theme/2nd wave multi resistance. Lulu for imperil makes this a lot easier along with Shiva for her speed up. Avoid breaks as the HP attacks are deadly.
Gau EX+3LBPenelo EX+3LBShantotto EX+3LB497k97gmshugohttps://www.youtube.com/watch?v=XdBIKJ_teic&list=PLr2tcQ1vq5eVhNY99GdLYb_NgBfO05e7QShivaPerformed this battle on March 2020 with Summon Board x6
Lulu EX+2LBAranea EX+3LBSerah EX+2LB587k82KainHighwind27https://youtu.be/7DmWYrammbQIfritSo this team admittedly requires some luck to get a full clear on, since there are no healers here, and the bosses like to use BRV-HP attacks. Also for Aranea to work, you have to make sure both Lulu's enchant and Imperil are up at all times. Waves 1 and 2 are the worst with doing Brv-HP attacks, so try to get them down as soon as you can. Final wave I use my summon early and focus the Celestial down, because it basically always uses Celestial Ray as it's first attack.
