a really big note is that it is. HARD. like yeah ur level 65 but some of these enemies are mirror dungeon extreme level

check that you're level 65. you've bought everything, or most stuff, from the shops in sisyphe. when you reach floor 2 in route 3, pick the path. if you picked ending A, kill the noirs. if you picked ending B, kill the rouges.
for ending A, i killed flannel in maison de noir at floor 3.
killing the allies (or going against the ending route) is how you bring in the Warden, which an indicator is if the fate lost screen pops up.
then, let the warden come to meursault and now you have to "defy fate" and exit sisyphe.

you have to dodge warden's attacks and keep fighting him until you reach the battle point in his health bar. kill the torches around the map to regain health, and kill a torch that lights up or at least overly punch it to stun the warden. (or let the warden punch it itself, idk, it just happens)

once you reach that point, youll battle the warden.

fighting the warden is kinda easy until you reach his Judgment... Sentencing... Condemnation! mass attack where almost or all of your sinners die except meursault and tbh theres people using their own teams so ill specify my own
uptie 4 evade defense team. they do not give a shit about the warden.

aim for the torches before going for the warden's attacks to minimize final power (higher speed to lower speed, torches to warden). sinners aiming for the torches must have least 2 coins in their skill. if not, then get another guy to attack (if the warden has less skill slots, that is)
POP EGO AT THE MASS ATTACKS!!!! MAKE SURE THE LOWEST SPEED AIMS AT THE MASS ATTACKS. IF HOPELESS -> EGO

haha theres a part 2

after the warden "reverses time", this is the real battle. this is where ill be detailing what to do for each skillset and honestly if every clash is dominating/favored you'll probably or more definitely land the attack

first lets talk about the status proof of confession where if you have some stacks of it you'll probably get a penance status and more clash power probably depending on the skill, so here's skills to avoid for each sinner if they have a select amount
3+: judgment, final power +2; judgment... sentencing... condemnation!; final power +2
5+: judgment, attack weight +1
6+: nail of punishment, final power +2; judgment, final power +3; receive thy punishment., final power +2; judgment... sentencing... condemnation!, final power +3
if sinner has 9+ proof of confession stacks, the effects of each skill arises:

• nail of penance: final power +2
• nail of punishment: final power +3
• judgment: final power +5, attack weight +3
• repent.: final power +2
• receive thy punishment.: final power +3
• judgment... sentencing... condemnation!: final power +5

the specific skills

atone before god.: if a sinner has stillness, make sure that guy clashes with the shield so it can deal 100%+ damage... and POP EGO FOR MORE DAMAGE CUZ [censored] YEAH
death unto the condemned: do not let the main target clash with it they will die. instead get a sinner with thumping pulse and make sure that shit says favored or dominating (clash power -15 happens if sinner with thumping pulse clashes with it)
judgment... sentencing... condemnation!: if a sinner has stillness, make sure they clash with it for clash/final power -5

ok thats it keep fighting idgaf

now ur fighting the chaplain yay (that wont let you read his stats for no reason at all)

theres a new status called ~ (thats just three effects collectively) and if you get more than 5+ stacks some skills will get buffed im too lazy to list which skills tho so figure it out take screenshots ig

at lower than half chaplain's health he basically buffs himself because its him
when "the manager" (DANTE???) winrates or uses the damage (basically the automatic buttons), or makes a sinner use a skill that has been 'nailed' then a random sinner gets damaged (that has to be the funniest feature added to the game)

it basically works the same as the warden lmao

once you reach stagger threshold a random scene happens and now you have done ℝ turns in the battle

once you reach stagger threshold AGAIN a cutscene happens. new sapling of light: TIPHERETH???????????????? oh yeah i think it stopped the chaplain getting more health and repeating the cycle

you're battling it again (and now you can kill it!!)

navigate ur way up, then when u die by... thing... get the scarf from blue girl and kill it each floor you go. after that, meet "pwie" (buffet) and punch buffet until u have to battle again

in order to win fast (not lying) you have to win a clash with the skill la jouissance so buffet can have "pwie's memories". five times. with each sinner having "shared with pwie" status. once its done, win a clash with another skill to win the encounter

if la jouissance is being activated, target rouge staff first before landing on buffet
make sure sinners with "shared with pwie" target buffet to lose SP

generally:
specific skills, do not use sinners that dont have bleed on those skills (read the hint)
make sure buffet doesnt get SP
stagger the rouge employee that has a second skill slot (the skill gives SP to buffet)

group egos are optimal in this case

in phase 2 its still the same objective just [censored] the rouges and ego spam (like you did first phase. good dog.)
