Ultimecia EX+3LBLilisette EX+2LBSherlottaInfihttps://youtu.be/_ExmxoBbsY4ShivaDebuffers help massively in this tier to dampen the damage from certain waves (the kraken). Lillisette is a great character for this tier and her overflow buff synergies extremely well with Ultimecia. Add Sherlottas 20% HP damage buff the bosses are in for a bad time
Ultimecia EX+3LBAgrias EX+3LBSetzer EX+3LBmzpro2https://youtu.be/efMAtKw1ECUBrothersEhhh this team is kinda an overkill, i might go back and try to make a budget team later
Warrior of Light EX+3LBAgrias EX+3LBFaris EX+3LBesb422https://youtu.be/D8s7Ef5Ut_sRamuhI will likely swap Faris out for Vanille, some time in the future. Otherwise, this is a fairly consistent clear.
Ultimecia EX+3LBWarrior of Light EX+0LBVanilleJin Leehttps://youtu.be/aI0jjeq_Qn4ShivaDispeller or debuffer recommended. Quick tips in video description. Initial clear with Serah, but freed after Vanille rework, since I purpled Serah at the same time. Serah (base EX) vid is here: https://youtu.be/GZMK77JSXDw
SherlottaSerahUltimecia EX+3LBFirezzhttps://youtu.be/Qkkue-ZR3BkRamuhInitial Clear. Note that I replaced Ultimecia with 3/3 Tidus in my second run to save her for future use.
Ultimecia EX+3LBAgrias EX+3LBLilisette EX+3LBSidra_Gameshttps://youtu.be/1QEyg9qQZdoShivaNo resists just danger, hardest of the initial 5 for me and I used 9 ingots to perfect. Beware blue ladies with 4 arms and swords, and do everything you can to keep her neutralized and limit her turns.
Ultimecia EX+3LBVincent EX+0LBWarrior of Light EX+3LBJelis Whttps://youtu.be/duyxXJHnSUcLeviathanHad to reset once on the last wave
SherlottaWarrior of Light EX+0LBUltimecia EX+3LBGaanrohttps://www.youtube.com/watch?v=A4-szXxRHm8IfritVoice Commentary. For Wave 3, I think the Marilith is the bigger threat of the two. Make sure Wol's shield is up before its AoE attacks, and that Elude is up after it buffs itself to avoid Max HP down. For Wave 5, I think the Kracken's the bigger threat since it's fast. Try to keep their HP split until Ultimecia's Hell's Judgement run out.
Ultimecia EX+3LBVanille EX+3LBAerithdethkab5https://www.youtube.com/watch?v=sOH0LtddKdIRamuhBring your dispellers/debuffers and a healer. In my opinion this is the 2nd hardest Tier. Wave 3 and 5 both enemies can buff themselves with general buffs. The marilith can apply some nasty debuffs such as Mbrv and HP down so becareful. Watch out for its all aoe attack, usually this is done when it's hp is less than half. Be sure not to get broken as it can entirely wipe your party, especially with the debuffs applied. Last wave the Tiamat enemy always starts off with an attack that will bring your brave down to 1 no matter how much you have. The kraken will also do an aoe brave attack which will likely break your characters, however Tiamat will follow up by buffing itself on it's next turn, so don't worry about battery-ing yourself.

Battle Data and more tips at the video description.
MVP: Ultimecia EX+3LB
Wave 3: Lich and Marlith loves hit hard. A tank that can prevent BRV breaks is recommended. Debuffs them when they buff.
Wave 5: Kraken can delay your party turns and mess up the turn. Focus on it first. Tiamat will drop ur party BRV to 0 with AOE attack. Dump your BRV.
Ultimecia EX+3LBSerah EX+0LBAerithTequila7https://www.youtube.com/watch?v=hl2EzWwaedILeviathanHave Serah & Ultimecia push off any buffs the bosses get. (They have 6 debuffs in total)
Do not let the Marillith break you if it is targeting all with its Flash Steel move & heal up after.
Watch the Kraken's target since it gains high turn rates and access to a brv-hp attack. Tiamat follow a set pattern of moves so adjust accordingly.
Ace EX+3LBRem EX+3LBSerahBatisathttps://youtu.be/siO3dH8jvGERamuhBest not to take a full break from wave 3, wave 3 can 100-0 you real quick if you aren't being careful. Abuse Rem's instant turns to make sure no one is at 0 brv before an ALL attack from sword lady.

Ultimecia EX+3LBAgrias EX+3LBFaris EX+0LBDaspharaohhttps://youtu.be/9uY0ufV9tNULeviathanHardest wave is third, they are both fast, their buffs are either unpredictable or on a high turn rate. Dispellers/debuffers are required. Took plenty on resets with this team.

Recommended Roles
Debuffer, Tank
Serah EX+1LBCeles EX+3LBKing EX+3LBRandantehttps://youtu.be/MwRBA-LMgQAShiva(1st run) Rem/Ultimecia/WoL (https://youtu.be/3PSjt5iVidU). (2nd run) Serah/King/Celes (https://youtu.be/MwRBA-LMgQA).
Ultimecia EX+3LBWarrior of Light EX+0LBLilisette EX+1LBSsvegettohttps://www.youtube.com/watch?v=Q64TuShY6oEShivaYou want shields from WoL for the mighty AoE from Marilith in wave 3, also either dispel their buffs or toss them off with a debuffer.
SerahUltimecia EX+3LBWarrior of Light EX+1LBXcaliblur 1https://youtu.be/kZc5TcVdbQwRamuhUltimecia is best used here. You also need a dispeller or a debuffer than can push off buffs.
Warrior of Light EX+0LBBartz EX+3LBYuffie EX+0LBAarolei/Leileehttps://youtu.be/KdneiILzZksLeviathanToughest Tier of the original 5 released. Make sure you can deal with damage dealt from Marilith's Flash of Steel. Watch out for ibrv wake up attacks from Kraken.
Yuffie EX+3LBBartz EX+3LBLeonUltima [ITA]https://youtu.be/CL-sK9rYKgYBrothersNo resets. I used this team to unlock WoL and Ultimecia for T7. My previous run with WoL, Lillisette, Ultimecia: https://youtu.be/MHgiMYSQzlU
Tifa EX+3LBWarrior of Light EX+1LBTifa EX+3LBTeleutehttps://youtu.be/suXX9gO6R0sShiva
Ultimecia EX+3LBKuja EX+3LBWarrior of Light EX+0LBPalladhttps://youtu.be/dCcTwuZLXZ0ShivaUltimecia and WoL pretty much carries this stage. Make sure to pay attention to Ultimecia skills and don't rush with her to get the EX up. I did it first try, no resets.
Fang EX+3LBRem EX+3LBUltimecia EX+3LBScarletClairehttps://youtu.be/L-lGvY6C_CkRamuhNot initial clear (first capture got a nice error message... but same team). One reset for wave 3. Debuffs, Chase and turn shenanigans were key to prevent enemy craziness.

Vanille provides good debuffs for a safe run and sherlotta boosts everyone's dmg
Lilisette EX+3LBWarrior of Light EX+3LBFaris EX+3LBAmateracu1991 DFFOO 2https://www.youtube.com/watch?v=F3czfUa2Hm4&list=PLavi_I0KPy9C3vsudcitQvP6clOw6Um-B&index=10RamuhWoL makes Marilith easy. Faris and Lilisette take care of the boss buffs by dispelling or pushing them off.

RamzaUltimecia EX+3LBWarrior of Light EX+0LBRed XIIIhttps://youtu.be/Lb4c8j1xM9EBrothersThe Marilith is scary and she needs to die fast. Get rid of Tiamat first because you don't want to lose your non-framed buffs every other turn. I held back towards the end because I was afraid I wouldn't have enough to finish the Kraken but I was overestimating it.
PoromUltimecia EX+3LBSerahGeneral Solidorhttps://youtu.be/eF6P9syjGs4RamuhNo gimmicky theme for this tier - Porom has great atk auras and a DEF II debuff which works exceptionally well and even confuse. Her healing is so good and you'll probably never die. Ultimecia is doing her thing as always dps checking and turn checking. And Serah for her debuffs/buffs/overflow/battery

LeonVanille EX+3LBSquall EX+3LBBig Alhttps://www.youtube.com/watch?v=t7U6vgTw7DcBrothersNo Sound in Video. This teams works by straight DPS combined with mitigating damage through Leon's EX, S2, HP+ (Self-heals), and Vanill'es attack down. Trash Waves: Use skill's for buff reapplication, otherwise HP+. Marilith Wave: Make sure to have Leon's EX applied at all times to fully protect yourself and gain battery through dual bosses attack's. Save Leon's S2 for when you take HP damage. Have Vanille keep debuff's off because their defense can make you hit shit damage. Do note that the marilith can jump turns suddenly so high turn rate moves to get in between should be used. Last Wave: Attack down is important for the Kraken since he uses water attacks. The Tiamat is not a problem because of Leon's EX except for it's firestorm attack but Vanille's attack down makes sure it doesn't hit hard. Save a Renzokuken or two for summon wave.
Warrior of Light EX+2LBLilisette EX+2LBUltimecia EX+3LBKainHighwind27https://youtu.be/cFdQy2AtzUQ?t=2079RamuhOn wave 3, after Lilisette inflicts the bosses with debuffs, try to wait until both bosses buff themselves to reapply them, so you can preserve her abilities. I focused Marilith first out of the two bosses. The final wave is where I used my summon, and I focused Tiamat first to avoid the Dispel as much as possible.
