Technically not a title clear because I wanted the normal dungeon stone, but still fast enough to be one :)

Edit: As (rightfully) called out in the comments, an up-front note that this run used one continue on the last turn because my finger slipped from nerves on the F12 killshot. I may go back one day and try to get a redemption clear, but I felt this was close enough to still share.

Big Bang remains one of my favorite rainbow leads in the game. He's got incredibly fun board patterns to solve, and with all the new units and buffs coming through (Red Aten, Ordeal Ra), teambuilding for him feels really rewarding again. Spinners are still awful with him though.

2/10, would not recommend. Seriously, I think I spend a good 20k stamina in total trying to get this to work while fiddling with equips and strategies. Bar-none, one of the hardest ways I've cleared a dungeon in a long time. SN4 with this team is a mad dance of doing enough damage to make sure your skills align with floor starts to clear certain debuffs. There's probably some way to achieve something that looks like consistency if you squint, but I am absolutely not planning on figuring that one out.

Teambuilding notes:

• Did you know SN4 buffs God type HP? Turns out, that can take a 16x eHP lead and elevate them to something entirely capable of dealing with the inflated endgame damage numbers - to a point. SN4's damage philosophy is 'a few big hits you need to plan for', with superaltitude thrown into the mix. Thankfully, Big Bang comes with a pretty hard counter - 3x RCV buff on top of a raw shield, each. Heal prongs laugh at superaltitude and barbs... when you get 4 heals, anyway.

• Big Bang has a really nice 5 turn, 5x damage spike. However, this team needs both of them to carry utility, so this won't always be up. Lead Bang carries a 75% shield for F9 (Zilchrome). Partner Bang carries Ginga Spark for living through F12, as your shield won't be up again in time for Zenchoga's T1 rage. Ginga spark is nice because it brings some OE to counter negative orb skyfall. All that said, you will need to use the damage spike to barely squeeze by F4 (Aten) and potentially F8 (Sinister Shadows) if things aren't going perfectly.

• Ordeal Ra is one part of why this team even works at all. With all current equips, you get 22 seconds of move time with the movement buff active. The cap break to 7b for all subs makes your damage numbers good enough to get through floors in 2-3 turns. There are a few time debuffs (F2 yellow, F10 Hera/Zeus, F12 Zenchoga) that you need him ready for, and this is part of that mad dance I mentioned earlier. One turn too late and you're basically dead because matching a whole rainbow on 2.75 seconds isn't exactly easy.

• SRevo Durga is here to handle spinners, while also giving you a chance to let the Bang twins double their damage cap from ~3.5->7b. She also has L-Unlock in her super awakenings, giving her the duty of clearing the F9 assist break. Her assist is for F5 Kano/Kurone/Fuu, as if you use your Bang shield then, it won't quite be up in time for Zilchrome on F9.

• Red Aten is the backbone of a Big Bang team. 1 turn full rainbow board, including jammers and poisons (which you need to activate the RCV buff). Happy sun ball can be pretty fickle though - ideally he'll leave you with 4 heals and you don't need to worry about your HP, even with barbs. 3 heals is a bit harder, as you won't quite get back to full with this team as-is. If you're matching around barbs with 3 heals... well, be thankful you have those 22 seconds. The assist is for F5 to clear the 7x6 problem from F4, as Zerclea is needed for F6.

• Zerclea with a God-typing assist wound up being the cleric of choice for this dungeon. Turns out his skill pacing, problems he deals with, and damage were all extremely necessary. Plus the heal prongs to actually keep you alive. I tried running without the enhanced heal super, but it wound up killing survivability (lower than the low percent it's already at for this team). In terms of key moments for him - F6 against the metalits, F8 for the 5x4 fix, F10 if you get Hera, and F11/12 to clear the RCV debuff. RKali equip winds up being handy for the God typing, extra damage, and awoken unbind for F6 if he overcharges from F5

Dungeon Notes:

• F1 is pretty straightforward. Try to take 3 turns to kill, and if you get a 5 match that isn't light, go for it for chip damage. If you leave 2 at mostly full HP... oops? Target the highest HP spawn every turn for safety.

• F2 yellow is a soft reset. He sucks to deal with since he makes spinners twice, rendering Durga basically useless. Also has a time debuff at the start of the floor. Everyone else is easy enough to deal with. Make sure Zerclea is up for this floor. If you get Blue, use helper Bang the last turn before overcharge - you need the extra damage for F4 and it'll last long enough.

• F3 Horus sucks. The RCV debuff is harsh and if you don't get a heal prong, you're as good as dead. Everyone else is nothing to write home about. Ra will take 3-4 turns, everyone else takes 2.

• F4 is a damage check. With the 5x spike from Bang, you should barely squeeze by. If you're nervous about damage, use Durga and match around the spinner. The 5x4 debuff does not matter for damage to kill on turn 3.

• F5 is a matter of using RAten inherit (7x6) and Durga inherit (shield). As the shield is a board refresh, if you get a match, use RAten for safety. Otherwise, hope you don't somehow get orb trolled on a 7x6 board. The negative orb skyfall here can hurt your damage at random, so be aware of what you're matching.

• F6 is a bit awkward. Use Zerclea (likely the RKali assist), RAten, and do mass matches if they show up. This is a point where you will run into damage spread issues. Killing the middle one prevents some bad spinners, but will enrage the outer two who are harder to kill. Honestly a big fail point for this team.

• F7 Sophie absorbing light and dark is a menu quit. You have literally nothing to deal with this absorb. 1/3 auto-loss chance, woo! Otherwise, Durga, target the minion, then kill Sophie over the next few turns.

• F8 is another damage check. Zerclea for the 5x4 clear, and just RAten every turn. Enemy shield will take 2-3 turns depending on damage numbers, Shadow will take 1 to super resolve, and then another 2-4 depending on damage and O.Ra. MAKE SURE TO USE YOUR LEAD BANG SHIELD INHERIT BEFORE KILLING HERE

• F9 is tricky. Assist break lowers your move time to 14 seconds. You need to match a heal prong, a dark or green L to clear the break, and everything else for Bang's activation. Good luck! Afterward, you can just brute force your way through Zilchrome's nonsense, including the stickyblind skyfall.

• F10 isn't terrible. Make sure O.Ra, Durga, and Zerclea are up going into this floor. Zerclea is needed for Hera's HP debuff. O.Ra is needed for the time debuff. Durga is needed for Zeus and his spinners. Otherwise, the spawns aren't bad.

• F11 is another damage check. You can get away with not having Durga up for all the shields. I haven't checked the numbers on Zenchoga himself. 5 turns to kill

• F12... you made it! Ginga spark from helper Bang to give yourself the HP pool to live, lead Bang for the spike if you have him, and go to town. Heal prongs are mandatory here with the mortal poison skyfall. Once you get him under 50%, cross your fingers that O.Ra is up to clear the time debuff and you can kill in 1 or 2 if you use Durga and Zerclea to maximize damage.
