This floor is most likely a loss for my team. Each battle is theoretically winnable.. sometimes even probable... but in aggregate, too much bad luck has to be evaded for too long. There might be a pass argument off giving the benefit of the doubt to the player team + strictly enforcing "turn 1" type status against the opponents, but eh. (For why I picked the floor with PC mobs that do well against my team, the boss-heavy floor was mostly lol, except the one fight that totally wipes me which would have ended up as Stocke solo vs. 2x Oz bosses. Double-acting MT Sleep followed up by double-acting MT Confusion is rough.)
Anyway, the floor gimmick means this is a "buffs and status" war. To see my team as having a chance, it helps to give Yuna Auto-Life (I know some don't give her that) as well as the "common steals or drops" armor customization. (Note that the Phantom Ring of elemental absorption does have a free slot, but that's also a one-way trip, so your call.) Said customization, whether the Phantom Ring can be kept or not grants 50% Death resist to Yuna. As a reminder, FFX Auto-Life grants 25% HP on revival, which would normally be lol, but is not bad when all damage is halved. (But thanks to the MT sealstone, Auto-Life will only hit 66% of the targets, so ~3.66 / 5.
Arnaud may well want to block ID as well for this floor, depending on how nasty a stat hit you apply if any.
Team Snowfire | Elincia, Yuna (MT), Arnaud, Stocke, Hawk
[Hawk: Ninja Master]
Floor 7b: Did you say "Final Battle?"
**Half damage is done and received on the first action of each team.
Team Snowfire vs. Katt, Rand, Bow, Nina2, Deis2, Jean, and Spar
Relevant from the other team: Bow has 50% ID, Nina2 has 35% ID, Deis2 has 80% ID, Jean has 80% ID. That's a lot of ID, although Jean & Bow are slow at least (well, Bow is average, which is slow enough to be slower than my entire team). Depending on how you interpret SD3 initiative, Hawk's Shurikens are theoretically super-fast, and can Slow Deis2 such that Yuna gets the drop on her? (More important if you deny Yuna the ID resistance.) Anyway, if Deis goes first and her 30% effective ID misses Yuna, or the Hawk shenanigans are a go, Yuna can cast MT Auto-Life which should help against the ID blitz a little. Arnaud's Slow Down should ensure Jean gets a turn approximately next year, or, alternatively, he can cast Hyper on Elincia and have her smite the hell out of Bow even through the floor damage halving. Stocke can revive someone if they got hit by Nina's ID, and his revival is 70%, or he can just Push Assault a beater or something to reduce their damage in round 2. If Hawk didn't have to do the Shurikens shenanigans, he can do his usual MT jutsu damage hammer to ensure the team doesn't get fried on round 2. Anyway, I don't think there's much point in plotting out this fight too closely: It's very swingy based on whether Yuna can be ID'd by Deis2 immediately, and then if she isn't, if the Auto-Life hits say 4 people rather than 3. (Nina2's ID isn't as important, again assuming you allow Yuna the ID protection at all, since Nina can't ID Yuna with it then.) With Hawk helping hose the enemy team's damage + usual Elincia evade, the only way my team loses is the ID blitz, but it is a fairly scary ID blitz. (Round 2 should be safer - Stocke / Yuna can get people back on their feet, the enemy team's damage is awful, Arnaud can toss Slow Down or Sleep, and Elincia can explode anyone, especially if she was Hyper'd.)
If you don't allow Yuna the ID protection and don't let Hawk use Shurikens to sneak Yuna a first turn, you should probably just vote fail now, my team would use up too much good luck. I think the ID protection is fair, myself, so continuing onward. Not normally a huge fan of this, but since this floor is scary as hell, Stocke should go farm gauge on the last few enemies. (Yuna has 1 MP cost, so that's totally fine, won't tax resources.)
Team Snowfire vs. Crono, Marle, Frog, Ayla, Magus, Robo and Lucca
Uhhh. Magus ID area hype time?! I think Lucca's sleep only hit an area around her, too. I have no idea how many duelers Magus's ID should be seen as hittable with, or if Magus can at all control who's in range (you can SORT OF manipulate this in CT with party order and knowing the set encounters really well, but I'm not sure I give enemy Magus credit for that.) Also there's the "wait until late in round 1, unleash DarkEternal + Twister to OHKO the world," but I think I can do enough damage to drop some characters to stop that strategy, especially if Stocke farmed a Turn BReak before.
Anyway, Magus has 50% ID Area, Lucca has Sleep over an area (but should never live to use it), Marle has ST 80% Confuse. Magus should whiff against Yuna and possibly Arnaud as well, and has trouble hitting Elincia. He'd like to target Stocke & Hawk, but it's not exactly in his control (Hawk can walk around if that matters, and if STocke gets a turn he can totally PUSH/LEFT/RIGHT ASSAULT Magus to somewhere less useful.) If the enemy team goes for the early blitz with MT (Luminaire, Dark Matter, etc.) that gets MT healed off as usual. Arnaud should be able to do something like Slow Down Marle to uselessness while Elincia tries to kill Lucca with the support of Hawk's Jutsu. So... this one is pretty doable, I suspect, although if Magus gets lucky in both his positioning and his hit rate, this can be trouble. (It's of course trouble too if you deny the status blockers, but I assume the team is already in deep if you do.) So... not as bad. Stocke can also just turn cancel Lucca if need be to get more time. If he does, farm up another one for the next fight, of course.
Team Snowfire vs. Yuri2, Karin, Joachim, Gepetto, Anastasia, Kurando and Blanca
Hoo boy. For Everyone? Trouble. Big trouble. Anastasia has nasty status, Blanca has MT healing, there's status healing and lots of blocking everywhere. About the only bright spot is that the SH2 cast doesn't block Sleep, so, uh, Arnaud can sleep someone briefly before they get healed by Blanca/Kurando/Anastasia? Yeah, this fight is straight lost unless Stocke has a farmed-up Turn Break to use on Yuri2, and gets the drop on him. (Which is actually true, albeit just barely.)
Anyway, Yuri2 is an obvious must-kill, but Blanca needs to die too, he's got MT healing & revival. Meanwhile Anastasia will be throwing status around... hmm, Slow Down is probably needed there, I think Anastasia's own Dispel is the only good answer to that. As noted vs. Gilgamesh, I do have answers to ST status-spam in all of Elincia/Stocke/Yuna having status curing, just there's a lot to do and little time to ensure Yuri2 dies before ever casting For Everyone on turn 2 and doing it without Blanca or Kurando interfering. Anyway... I think it IS winnable, but eh, probably requires good luck. Since the BoF2 fight also requires at least some luck, winning the floor in aggregate is tricky.
May return later, but tired now. Abstain for the moment.
