FFX Challenge - Finished. The entire run was actually really fun since if often required some additional thinking on team composition as well as the strategy to use for each fight. SPOILER: The slower, steadier method often was the winner. Also highlighted for me how much more valuable certain abilities were.
Bikanel - Having Kim learn White Magic made him invaluable here, but Rikku is the real star, thanks to Al Bhed Potions (ABP) becoming available. MT 1000 Healing is quite a lot at this point in the game! For more enemies, the team of Tidus, Kim, and Auron was actually the best mixture. This is due to the fact that the birds in this area don't have high M.Def so Kim/Lu can actually Overkill them easily for bonus AP. Sandragoras, which were probably the scariest monsters due to 100% confse, I just launched with Auron's Shooting Star. Certain enemies however are better taken care of with Lulu - namely Sandworms and Zus. Both get destroyed by POIZN, so Bio was invaluable (Auron can Guard to keep both Lu and Tidus safe while waiting). Wakka, of course, still rules against pretty much every random formation. I just benched him so he wouldn't go way ahead on the Sphere Grid - this had the effect of making him weaker than I wanted for UNDEAD EVRAE. More of that below.
Home - Kim's Stone Breath owns everything, so planning out how you spent your Lancet draws helps a lot. Auron also has Shooting Star here to own the occasional monster. Some small things of note - Auron's grid at this point picks up a couple of Str+4s in rapid succession, so he's starting to deal *lots* more damage than everyone. One of these areas actually overlaps near where Tidus is, so I had him take a quick dip to pick up some additional strength so he's aiding a bit more as well. Most notable, ESG exchanges 4 of Auron's MP+20 for 4 Strength+4s. Kind of a good trade, most of the time.
No encounters on the airship. Not surprising since its a short segment.
Evrae - Due to it's Stone Gaze, I pretty much had to use Kim/Rikku/Tidus unless I want to risk it never hitting my healer. Nobody has a Stone Ward/Proof armor otherwise, so this was definitely the safest way to deal with him. Immediately pull back and let Cid do his 7200 damage, while Tidus buffs the entire team with Haste and Cheer. In the meantime, I have Kim cast up Protect and do some damage with spells. I Lancet after around the halfway point to keep his MP high. Once the Cheers were up and Cid has done his deal, I wait for a bit before moving back in, having Kim chip it down some more. When we move back in, Tidus attacks every turn possible. That extra strength really doing some good work here! Kim also attacks with the occasional black magic, but I usually had him and Rikku stay more defensive to cure off any status that comes by since it's by far and away the scariest thing in this fight (most damage can be shrugged off easily - especially with Protect up). I only had to deal with him Hasted for a few turns as Tidus had a Overdrive ready and I burn through the last 6000 or so of its HP with that and another spell from Kim. Saving the Mix was pretty ideal for Bevelle's aquatic portion.
Bevelle Ceremony - Easy. Just have to make sure that the tall robot isn't getting KO'd without some damage on it so it doesn't accidentally knock out any one I need too early.
Via Purifico - So for the first time I thought I'd need to summon due to Yuna being solo for the opening stretch of this dungeon. Then I found Kim before the first encounter, so so much for that. Kim is a pretty good first partner all things considered since his magic is strong enough for most things here, has some semblance of accuracy for the lizards and Lancet to keep his MP in stock. I do eventually get all 4 party members together even though you could just make a straight dash to the exit so I could loot a little more efficiently. Nothing really of note. Issaru kinda sucks on any regular playthrough where Yuna has some access to the Sphere Grid so yeah.
Bevelle Aqueducts - I bet most of you completely forgot this was even a thing, cause I sure did until I was going over all the boss fights in my head. Anyway, this is possibly the first time I had to do this fight legit due to the "No Items except Kim" clause. It's a good thing you normally just throw 2 P.Downs at him because his counters hurt...and he has Eraser. Oh boy. The small bit of good news is that his HP kind of sucks (16000 only) so it's just a matter of attacking when possible. For NEB - I'm not sure what causes him to do Eraser, because as long as the fight took, I never saw him use it a second time. However, his first move was Eraser so I feel like that part is scripted. The good news for me is that he removed Wakka because if it was anyone else, I might be screwed (removing Rikku kills my Healing, Tidus has the most damage). With the remaining 2, Tidus does the rest of the work while Rikku keeps him healthy. I secure the finish with an Overdrive again.
Natus - I get Yuna caught up on Sphere levels as well as Wakka since I avoided using both for awhile. Kim/Yuna/Tidus are forced into this fight so I don't have any choice on the matter. Luckily, this is also one of the stronger formations for the fight. Why? Because having both Kim and Yuna gives me 2 Healers. ESG allows Yuna access to Reflect which lets me cruise in the 2nd part of the fight. I still have to get there. That's the good news. The bad news is that outside of Tidus, no one really has much offense. He does get a Talk boost here, which helps immensely when your sole offense is from one person. I try Hasting up initially but the Mortibody is able to MT dispel, so I eventually drop it and just go straight to whacking Seymour. Double Nulcasting means I can stay ahead of the 1st phase relatively well and having Items means I can throw Reflect with Yuna and can still Heal up. Overall pretty basic - Standard might have made this harder since Yuna is farther away from Reflect. Of course, I could also have done it grindless and it would be a different story.
Calm Lands - I open up Monster Hunting with Tidus/Wakka/Rikku for the most part. It's effective against most formations sans the 2 Chimeras and the 2 Hydras. For that first, I need Kim or Yuna...usually Kim since he has some offense. For the 2nd, Auron/Yuna were usually a better choice. I keep Tidus in the team all the time due to Sonic Steel and access to flee. But Rikku having gained an Initiative weapon makes her a good choice to place upfront some of the time too, just to void Ambushes altogether.
Cavern of the Stolen Faith - Not much changes in formation line up. I use Tidus/Kim/Wakka mostly for balance. Yojimbo as a boss goes down without much of a fight. I then proceed to hire Yojimbo by literally throwing a good chunk of change of him. This will come back to haunt me come Mt. Gagazet. Capitalism, amirite?
Biran/Yenke: Are bad and should feel bad.
Mt. Gagazet: The climb up the mountain features utilizing a team of Tidus/Auron/Rikku for the entire journey. At this point, Auron has gained a massive amount of Strength and is doing enough to pretty much one shot the Grenades. I do one better and forge an E&C weapon on him. With access to Guard (and later Sentinel up the climb), this basically lets me troll the hell out of ST physicals, which is a lot of enemy attacks. Sure, there are a few enemies that don't use it, but they are few and far between and most everything else gets destroyed with this formation, allowing Rikku to stock up on some goods. The only things that possess some issue are the Imps, which only have a measly 800 HP. Hasting Rikku and dropping 3 Grenades usually works. The alternative is to just save an Overdrive and wreck them that way.
Wantz has good weapons for Yuna/Lulu/Rikku. The bad news is the combined cost is about 310,000 gil and Yojimbo took a good chunk. Since I need some levels on some other PCs AND I want the weapons just in case, I force myself to grind here.
Flux - On Standard, this might be a bit of an issue because many of the formations here have some holes. Going over what everyone brings to the table:
- Tidus: Has Haste. Less offense than Auron, less HP than Wakka. Awful MDef means Total Annihilation will probably still kill him after Shell.
- Wakka: Has almost nothing. Less offense than Tidus and less HP than Auron. Bad combo in general for this fight.
- Yuna: Revival! No offense unless other PCs die. This also means no reliable Aeon Shielding. Has extremely bad HP (thanks to ESG) so Cross Cleave will probably one shot. Might even after Protect?
- Lulu: Slow, has to worry about MP, but lots of damage and defenses. Almost has to be paired up with Kim due to the MP
- Rikku: ABP with Survivor is 2k MT healing with fast recharge. This is really really good. The downside is that she has no revival, and since one of Flux's combos is lol u ded, I can't bring her in reliably as the only healer. Offense varies depending on who is with her, but would prefer Lulu for the best due to the abundance of Fire Gems. Lack of focusing is an issue
- Auron: Has the best HP and best resourceless offense. Unfortunately is also extremely Slow. Will definitely survive Total Annihilation under Shell.
- Kimahri: Balanced on offense and defense, but offense isn't super strong (it's worse than Tidus, above Wakka and costs MP). Better HP than Yuna for defensive duties.
After that analysis, I settled for Auron/Kim/ and didn't know about the third. Since I didn't want to be relying on just 1 reviver, I threw Yuna in there. The beginning of the fight was actually scarier because once you figure out how to survive Total Annihilation, he starts going into a predictable pattern and it becomes easier to react to. By Shelling Auron/Kim, both can survive that and both have the HP and defense to eat a Cross Cleave as well. Still want them under Protect though. Yuna fares a little worse on Cross Cleave (must be under Protect) but can survive a Total Annihilation without Shell as long as she maintains high HP. The fight is a very slow slog since Auron is just so slow and Kim's offense is merely "okay". But with enough pokes from Kim and the occasional swing from Auron, the fight eventually ends. This fight is probably tougher in Standard since Auron has a much smaller offense advantage, but I assume it goes very much the same way as long as you can survive his big call-out attacks, just slower.
Gagazet caverns - We're getting into the stretch of the game where everyone is nearing the end of their grids...kinda. Lulu and Kim still have ways to go (Kim is special) as does Rikku. But for the most part, Wakka/Tidus/Auron are all sitting pretty now in their last segments. Most of the encounters here get owned by more E&C. There are a few that don't (eyeball bats) and for those...Wakka makes a good choice. Note that I don't say he's the best because ESG removed enough strength from Wakka such that he sits at the end of his grid at a paltry 43 or something - which sometimes isn't enough to kill late game eyeball bats. I forget if he had even gotten the last bits of strength here so I actually need Tidus with Sonic Steel to Haste him so he can go twice quickly and kill it. Tidus/Auron/Kim was otherwise my go to party with me saving overdrives primarily for the eyeball bats. Dark Flans in International apparently lost Auto-Regen so Armor Break into anything after tends to kill them quick.
Sanctuary Keeper - 1st reset of this challenge and it's because of underestimating Mana Breath. I figure for this team, my best bet was Auron/Yuna/Lulu. Kim doesn't have tier 3s so his offense is not very good. Wakka and Rikku don't bring much (lest you Mix 2 Wings and Trio the boss to death). This really only leaves Tidus as the other option and I figure that going magical was a better route than trying to kill it with physicals. While you can armor break it, it will counter with Protect to mitigate the damage. On the other hand, it won't stop you from mental breaking him. The issue though is that this boss is really tanky so I have to be careful with my MP on Lulu otherwise, I'd be a sitting duck. I could technically use a Black Magic Sphere to pick up Osmose, but decided to go true OSG here.
Anyway, the reset comes due to underestimating Mana Breath. Yuna was sitting around 1800 HP or something (again, note ESG removes a lot of HP from Yuna) and I was thinking after seeing that attack almost kill Lulu the first time, "Should I Shell Up?". I did have 2 Focuses under my belt so I figured I'd be able to survive it, if barely, at full health. lol 2000 damage OHKO her and I lose my reviver pretty early on this attempt that I knew I'd lose the following attrition war. The second time around, I don't take chances. I constantly keep Yuna and Lulu at full health as much as I can. With E&C, Auron can sometimes sneak in a few counter hits with Sentinel since I also didn't want to accidentally trigger a Tail Sweep. This helps reduce the amount of damage Lulu needs to output, as does Focusing up a few times before casting. I eventually beat it all the while juggling healing, counting attacks for tail sweep and curing random status from Photon Wings. Overall, very challenging even though I wasn't expecting it to be a complete pushover to start.
Zanarkand Road - Same enemies here as Gagazet cave pretty much. I run Tidus/Kim/Auron,
D.O.M.E - Tidus/Yuna/Auron or Tidus/Kim/Auron are both good parties as it deals with Defender Zs pretty easy and the two mechs have issues trying to damage the party between Auron Sentinel guarding and Kim being able to heal. I do eventually catch up party members after reaching the end, before the trials. At this point, Tidus/Wakka/Auron are done their grids. Lulu picks up Double Cast and Kim finally gets to tier 3s. Good thing too as the next couple of bosses kinda want it
Spectral Keeper - I run Yuna/Kim/Auron so I can control Berserk somewhat. I probably should've wiped here but ended up clearing it first try due to utter dumb luck. The strategy is simple: Keep everyone one space apart so Spectral Keeper can never hit the entire party. Auron lands a Mental Break early, and Kim deals with the bulk of the offense from tier 3s, although Auron helps out whenever his turn comes up. I dodge the first 2 glyph mines pretty easy, but then the next time he summons them, they instantly explode and kill Yuna and then Kim. I was pretty sure I'm screwed at this point since both healers are dead. Then he Zerks Auron (lol) and Auron proceeds to whack him upside the head for about 8k damage, finishing the fight. Whoops!
Yunalesca - All mage party is the team of choice due to Mind Blast. Kim/Yuna/Lulu deal with this fight about as well as can be. At one point I do almost screw myself over because I got too clever and casted Reflect on Kim so I have someone safe from the curative spells under zombie. Unfortunately, Kim got confused at a critical moment and I needed to control him. I was pretty sure I was screwed since I couldn't use items, my only recourse was to try and smack him with a physical. Luckily for me, Lulu does get like 11 Accuracy on ESG and that probably made it more likely than not I ended up knocking Kim back to his senses. The rest of fight is just being very careful about HP levels. I usually ignored healing and focused on just straight up nuking (especially with Lulu) so as to get through the fight quickly and with less randomness.
Sin Fins - Tidus/Auron/Kim takes over. The first time, I almost get owned by DELAY HAX. But Tidus recovers in time and I get Cid to pull away before any more damage is done. Negation makes Hastega a waste, so I just tended to Haste up Kim, and had him nuke from a distance. When Sin's Core appears, it doesn't fare much better and it goes down to a combo of Auron/Kim and the occasional Tidus attack.
Sin Damage Race - 2 Wipes to this fight (lol). I first tried Kim/Lulu/Tidus, thinking Hasting up and throwing spells at it quickly will be enough. Unfortunately, I forget it has status and I get promptly owned by that, when it hits Tidus and then he kills Kim. Oops. I swap teams to Yuna/Kim/Lulu, so I have two people who can recover from random status. Unfortunately, Yuna hasn't picked up Holy yet and most of her turns are tied to healing everyone since the attacks also 3-4HKO'd me (I don't have HP+30% armors...yet). And uh...I actually legit lose the damage race here because Lulu is just so slow and Kim also has to waste turns healing her MP periodically. I change parties back to physicals and roll, Tidus/Auron/Yuna. This time, Tidus manages to resist confusion that I don't have to worry about it and Hastega with the 2 physical attackers manage to kill it with a few turns to spare.
Inside Sin - I forge a E&C weapon for Tidus here as well (along with First Strike) because guess what all the big bad randoms inside Sin are vulnerable to? That's right, PROVOKE. Not only does Provoke work, but it also turns them to using evadable physicals, so Tidus with a E&C weapon and First strike here pretty much eliminates a ton of threats. These include: Gemini twins, Great Malboros, Barbarossa, and King Behemoths. I also learned that if you kill a King Behemoth with a counter attack under Provoke, it won't death counter with Meteor, so Tidus was by far away the best choice. For the other two slots, I kept Yuna and Kim. Yuna got a Stonestrike weapon, which at first seems useless. However, as it turns out, it has a lowish chance to hit Adamantoises so she ends up killing those whenever they pop up. Meanwhile, Kim has Petrify breath for the 3x eyeball formation, which is by far the worst formation since even a Hasted Wakka can't take them out effectively. They instead die to MT overdrives and as Auron was already at the end of his grid, I just picked someone else who can do the same. Along with Tidus having Energy Rain now, I just need to not fight them 3x in a row which doesn't happen during this run.
Seymour Omnis - Auron/Kim/Tidus. Tidus Hastes up the team, while Auron lands Armor Break. Then Tidus swaps to Double Edge and just Quick Hits like crazy. He does get off an Ultima which kills everyone but Auron, but at that point, it doesn't matter as Seymour rolls into Ice Element and Auron conveniently has an armor with Iceproof equipped.
BFA - 3 tries for this one. You're forced to use Tidus/Yuna/Auron. First couple of tries, I forged armors with Wards for Stone and Zombie on everyone. I also grabbed the 99 Stamina Tonics (as NEB advised) and made HP+40% for everyone. This ended up being not good enough as the status still does through and I lose basically once Yuna gets Zombie'd as I have no way of curing it. For the 3rd attempt, I ended up going out and grinding a little for the items to make proofs. This way, the random status doesn't own me anymore. However, I am worried about BFA's 2nd form first phase overdrive as I have no way for Yuna to survive it. Even with HP+40%, Yuna tops out at a measly 3120 HP due to ESG plot and that 1st phase OD deals like 5800 damage. I manipulate Tidus' Talks to get around it but then I rudely found out that Ultimate Jecht Shot does just about 3000 damage to Yuna. Since she got hit a little bit before hand, this means Yuna dies and its still not late enough into the fight that I can make it without healing.
On the winning run, I modify the armors a little but again. I managed to steal enough Blessed gems with Rikku to get Def+20%. Since I need Yuna to survive, I give her HP+50% along with the two proofs. This lets her hit 3400 for HP, which is much more comfortable margin. I give Def+20% for Auron because really, with only HP+30%, he was already hitting about 6k for HP. I also make One MP Cost weapons for all 3 so MP doesn't become an issue. Lastly, I give Tidus/Yuna damage+ modifiers on their weapons (Str/Mag) and a Sensor ability so I can keep track of BFA's HP.
The first form goes about as expected. I do learn from NEB that I can Slow the Padogas, so I cast Slowga until both are hit. Then I have Tidus Haste Up and Cheerx5 on everyone. Meanwhile, Yuna throws Regen and Protect on everyone as most of BFA's offense is physical. Regen allows me to heal even when it's not Yuna's turn and helps immensely for turn economy as I want Yuna to help with Holy here to blitz past the 1st phase of the second form. Auron uses Sentinel initially but as the battle goes underway, he does use Armor Break when Tidus can get turns after him and before the Padogas. This left Tidus unload a few Quick Hits for boosted damage, which helps speed things up. When the 2nd form come out, I do throw out Tidus' OD to quickly blitz past the 1st phase. I also use Talk once here to keep BFA placated so Yuna doesn't randomly die too early again. Once the second phase hits, Regen keeps me safe especially when the Delay sword hax starts coming out and I can't inbetween as Yuna's turn is pushed back. I do have to recast Regen at some point but sticking to the plan and having an additional Talk charge at the ready, I kill BFA on the 4th run with some room to spare thanks to Auron entrusting his OD to Tidus once the kill range is within sight.
Yu Yevon - I thought I was stalemated for a bit when it drained all of my MP. lol, shows how often I fight this guy >_>. Anyway, he eventually kills himself with Gravija so just be patient. Auron having a Poisonstrike weapon helped since it procing would speed things up.
And that's all the main game fights! If I figure out how to modify the challenge for post game and side content I will do so, but don't expect much for now.
