General Information
| Core | Around 17 HP Bar |
| 1 Summon Port | Around 13 HP Bar |
Moveset
Mother Whale’s moveset rotates from Step 1 to 4 for this stage.
- Launch Massive Missiles.
- Launch Raptures and also generate defensive barrier. Raptures come in 4 waves.
- Hurtle.
- Launch Master-Grade Raptures.
During the second rotation, there is a chance Mother Whale uses Laser Shower when the 2nd wave of Raptures launched.
Launch Massive Missiles
These missiles actually hurt and lowers your DEF, try to clear all of them and cover the remaining ones if needed. Having Modernia and using her burst here helps a lot.
Ultrasonic Wave
Mother Whale emits a wave that buffs summoned raptures ATK AND providing them with hit count HP instead (you have to land enough hits on each rapture to kill them).
Breaking Mother Whale’s core will stop it from using this move.
Launch Raptures
The 2nd most annoying part of this fight. Mother Whale summons a bunch of raptures that are normally very squishy but…combined with Ultrasonic Wave, can heavily damage your team not to mention the hit count HP buff.
A barrier/shield is also generated. With the barrier around, only Electric units are able to damage Mother Whale, not even piercing effects can get past the barrier (Alice, Dorothy attacks and Snow White/Maxwell burst will not go through). Only way to get rid of this barrier is by clearing any remaining raptures on the field.
Fortunately this barrier only activates once, which means you just have to clear first wave of raptures and no more barrier will be seen.
There are 3 ways to deal with the raptures here:
- Use Dorothy. Her Skill 2 and Brand damage from burst is able to ignore the hit count HP. Since the raptures are squishy, Dorothy’s skills will just wipe them out easily.
- Use AOE burst to kill them right when they are spawned, there is a 0.5s-1s duration where the hit count HP isn’t applied.
- Using fast firing rate units (Machine gun) to kill them 1 by 1. Modernia works best here since her burst allows her to hit multiple raptures at once.
Hurtle
Mother Whale begins to charge up and flies towards your team. This move takes at least half of your units HP if it lands, take cover against this move.
Launch Master-Grade Raptures
The most annoying part of the stage, unless you are have enough damage to kill Mother Whale before this move, or dropping its HP low enough so that 1 or 2 units surviving can finish it off.
Mother Whale summons a bunch of raptures that will wipe out 3-4 units on your team even with full cover. These raptures are also very tanky, wiping all of them is near impossible unless way higher CP than stage recommended.
The way to survive this move is to have a taunt unit and/or healing/invincibility, where the taunt unit will soak up most of the damage, allowing the 4 other units to survive. These units will be mentioned in team comp suggestion below.
Note: These raptures will ONLY go away after using their attacks, stunning them and hoping that they will go away after a few seconds does NOT work.
Laser Shower
Used when 2nd wave of Raptures are launched during second rotation.
Tips
- The summon ports I (the ones on top) have least HP compared to the ports II and III. If you need another 13 HP bar of damage, aim at ports I as you can destroy them much quicker.
- Using units with huge damage that Pierces works great here, since you can deal massive damage to 2 or 3 ports at the same time. (Alice, Snow White, Maxwell)
Team Comps
Having at least 1 taunt unit is highly recommended to deal with the master-grade raptures. Having 1 healing unit is also recommended to increase margin of error.
It is possible to just go full DPS if your DPS units are very stacked.
| 20s B1 | Taunt | B3 DPS | B3 DPS | Flex |
 Dorothy |  Makima |  Alice |  Maxwell |  Rapunzel |
 Liter |  Snow White |  Modernia |  Privaty |
| 20s B1 | Taunt | B3 DPS | B3 DPS | Flex |
Dorothy |  Noah | Alice | Maxwell |  Guilty |
Liter | Snow White | Modernia |  Novel |
| 20s B1 | Taunt | B3 DPS | B3 DPS | Flex |
Dorothy |  Noise | Alice | Maxwell | Guilty |
Liter | Snow White | Modernia | Novel |
| B1 | Dorothy is the best option for this fight (finally not a granny) as she provides CDR and huge part damage buff, which helps greatly since Mother Whale has a ton of parts. Dorothy’s burst and Skill 2 wipes out squishy raptures with ease. Using Dorothy also allows you to not use any machine gun units in the team, which frees up flexibility to add healing or buffers. Note: You have to manual Dorothy’s burst and aim at Mother Whale, the burst can sometimes miss. Liter is the 2nd best option (not that far behind Dorothy), as she provides CDR and huge ATK buff as usual. Only issue is that using Liter requires you to have Modernia in your team to deal with the squishy raptures with hit count HP buff. |
| Taunt | Makima is able to taunt the master-grade raptures and survive using her invincibility from Skill 2. A healer is highly recommended if using Makima, since she has to survive for burst rotation. Noah is also able to taunt the master-grade raptures and her burst provides invincibility that allows herself or at least the other units to survive. Another 20s B2 unit with offensive capability is needed if using Noah. Noise provides taunt and her burst provides Max HP buff that increase chances of other units surviving. Note 1 : Noah and Noise dying is fine since you can continue using burst without them. Note 2 : There are clears I saw using Diesel, but I have not personally tested her in this stage. If you have none of the 3 options, giving Diesel a try might work. |
| B3 DPS | 2 B3 DPS units are needed for smooth burst rotation every 20s. Top options are Alice, Snow White, Modernia, Maxwell, Scarlet. Notable mention is Laplace if you somehow raised her over Maxwell.. Alice, Snow White, Maxwell do the same thing, dealing huge damage that pierces through multiple parts, which helps you to destroy the Summon Ports fast, or if they are absurdly stack, you can choose to just destroy the core from the beginning. Modernia is the best option to deal with the annoying raptures if you are not using Dorothy, since Modernia is a machine gun unit and her burst allows you to damage multiple raptures at once. Scarlet still deals good damage against Mother Whale, and she can wipe out 1 wave of raptuers if you time her burst correctly. She is also able to get past Mother Whale’s barrier, but that doesn’t quite matter here since you have to get rid of the raptures anyway. |
| Flex | Healing options are Rapunzel and Soda, which are used with Makima. It is recommended to just stack up more damage and blow up Mother Whale quicker if you use the other taunt units. B3 flex options are Privaty and any of the B3 DPS mentioned above. You can choose to add 1 of these into the team if using Makima and not have any healing options, or if you want to go the full DPS route. B2 flex options are Guilty, Novel, Rupee and Viper. These units are used when you use Noah or Noise, since you need a B2 unit to form a complete team. |
Just have a high enough power level and it’s ez gg
Dorothy’s skill 2 and burst no longer bypass the hit count HP on summoned raptures, at least on the Solo Raid version of the boss. Her skill 2 and burst both deal 0 damage to all summoned raptures while the Ultrasonic Wave buff is up.
Correction: burst actually does bypass the hit count HP, but skill 2 does not
Skill 2 does bypass, just beated Mother Whale today
Is it true that Laplace true damage skill is ineffective
i killed all raptures but shield is still up and after that mother whale proceed to one shots my team its so frustrating that i didn’t get modernia or dorothy after all this time
Actually, it seems the mobile version has an issue where the screen doesn’t show properly all the raptures, unlike the PC version.
Been stuck here for weeks. Guess I’ll never know what happened to the commander and Johan :'(
Same lmao. What a BS boss!
aaaand, 2 months later, I’ve defeated it.
I don’t have Dorothy, modernia, or snow white since i’m unlucky, i just can’t seem to be able to pass the boss
complete and utter trash boss, shame to have this in what would otherwise be a great game
I was getting stomped when I tried the stage, read this guide, only did like two things it said, and easily cleared it. Pretty nice.
really hate this boss but if you are struggling with those hit count ruptures, i would recommend trying baby snow white. my team comp was liter, noah, rupee(my strongest b2 20 sec cd so swap with yours), modernia, and baby snow white. the back and forth bursts between modernia and baby snow white is nice
this is a great reccomendation, its crazy how much i was tearing my hair out before trying an underleveled smol white. still havent won yet but got down to 50 bars as opposed to 90 on really good luck.
1st couple of tries were with makima that go the full timer but only gets it down to 100 bars because all the bursts are for the lill guys, keeping makima alive and surviving the bombs
2nd was just bruteforcing various nikkes like my special item dolla and laplace but laplace is just better than most against the rapture spawns unlike modernia. and neither red hood or alice is very good at taking out the bombs so it really makes it awkward where rh is just bursting for nothing.
the smol white with bad bursts and her only at 4/4/4 outclassed them all and with dolla just facetanking the elites. so im sure with slotting in real gear and skilling it will be achievable soon.
I tried it today(18/12/2023), and Dorothy Skill 2 doesn’t work anymore. (Or I’m doing something really wrong.)
For those thinking of full dps (never got dorothy to work):
The core can be hit right from the start (you’ll have to manually target it probably, it’s the red patch below). If you can burst the core down before it spawns the barrier (which is usually at/after your first burst rotation), it won’t trigger the shield. I did it with my standard team of liter / centi / scarlet / Red hood / anything really. Trigger all 3 red hood burst, and manually target the core, it’ll align firepower from the whole team during the burst, I managed to burst it down by the first rotation, and the rest is fairly easy. Get rapunzel if red hood dies afterward and you still need her to clean up.
Mind you, I had 19k power vs a 14k suggestion, and a 3*+2 red hood, screw this boss man.
This worked for me, luckily I had red hood 3+1 (37.2k power) and just burned the core. Total of 17k power. I’ve been stuck on this boss for months. The other in my team was Liter, Dorothy, Scarlet Black & Blanc.
Thx Man it worked for me ! Full manually burst on Core ! Was stuck for weeks !
Liter / Naga / Crown / Asuka / Alice
14k
Tried doing this several times even managed to burst down the core but only after losing most of my team I have 16k power to this bosses 14k kinda bullshit.
Took several tries but I beat it with Dorothy / Noise / Alice / Scarlet / Centi! I mainly controlled Centi to keep as much burst gen going and using Scarlet+Alice to wipe ports, Noise to absorb/tank and Dorothy B1 to wipe as many mobs.
I had 162K power so roughly ~20K above the boss.
Thanks for the guide!
I found that Red Hood + Scarlet + Naga + Dorothy + Electric is basically a cheat code and can beat the boss before the 2nd rapture wave, even with 10k CP under
oh my got THANK YOU. This boss has been the bane of my existence and god did this team deliver
Finally after 2 months i got it. party level at 219: Liter, blanc, red hood, Noir and scarlet. Red hood without any dupes, fully leveled skills. Strategy very similar to beating modernia you HAVE to destroy core first before doing anything else, after that the battle is a breeze even on auto. (Red hood nuked the core btw)
I did it on a 20k power deficit. Liter, Crown, Alice, Modernia and Noise. Focus on the summoning ports with alice, Modernia for clearing out 1 dmg raptures. Noise tanks the first real rapture wave that does a billion dmg. Just keep destroying it’s ports
THANKS MAN – worked great
thanks for the guide i have been 3 months suck in here adding little snow white and using noah really helped me i was like near 170 000 and still was not able to beat the boss didnt understand how the barrier thing worked, by far the worst boss so far
Gotta give a quick shoutout to Blanc + Noir to help me through this fight as well. The heal + indominability from Blanc along with Noir’s dmg up to parts allowed me to just brute force it with Modernia while Noise took most of the damage.
10k-ish deficit, any strat other than hard focusing the core would get me killed by the third normal rapture wave; i ended up making teams with completely defective burst rotations just to be able to deal with missiles while also buffing red hood enough to destroy the core before the first wave spawned, this worked slightly better but then the master wave would just wipe my team; adding a tank to try and survive the master wave resulted in either not enough buffs to kill the core or no way to clean up the missiles; overall this fight is complete bullshit
then i pulled crown and she proceeded to effortlessly out-bullshit the boss
crown singlehandedly let me nuke the core in record time, from there the fight was free outside of the master wave but this time i had space on the team for a tank (thx noah)
I have Red hood, rapi: red hood, liter, Crown, Naga, Tia and Ice maiden. What would be the best comp? Thanks
I’ll only say: Liter, Marciana, Red Hood, Smol White and Dorothy.
I beat it with 141k of power in 1:16 minutes.
Modernia, Redhood, Liter, Crown, Dorothy.
Used Redhood B1, Crown B2, Redhood B3 to kill core
Then used Liter B1, Any B2, Modernia B3 to kill all additonal mobs.
Took Cover on Master Raptures.
Then had Crown invincibility + taunt to tank Hurtle
Then Liter B1, Crown B2, Redhood B3 to finish.
This guide helped me figure out the barrier but then I had to try a few different compositions to finally complete. I think my completion was mostly dumb luck but yknow I won XD
This fight is just bullshit and not fun, whoever designed it should be shot into the sun
If you’re stuck in this stage for a long time follow this tip.
And keep reading if you have at least Dorothy and any DPS that can destroy the summon port when in full burst.
I beat it today after a week thinking that there no way I’ll pass this stage without Modernia.
I tried using Dorothy before but doesn’t seem to get her AOE work at first and I start trying using Dorothy again today and it worked.
My team comp was Dorothy, “Borrowed” Marciana, Alice, Summer Anis, Liter with 146k power level.
Dorothy is the key here her skill 2 and burst AOE still work.
Alice main DPS to destroy the summon port
Summer Anis, Liter are my 2nd and 3rd unit with highest power level + Marciana just to pass the power level.
– Start by focusing on the summon port and ignore the bomb, take cover if needed. 1st full burst should be using Liter and save Dorothy later.
– 2nd phase, just need to time Dorothy’s burst right after the 1st wave dropped, the 2nd wave will dropped and after Dorothy’s burst end all the raptures are wiped. 3rd wave may need some RNG (I guess) because Dorothy’s 2nd skill triggered and wiped them. Remember to focus the summon port whenever you can.
– Take cover when it charged and start focus at the summon port from here.
– 3rd phase, the master graded raptures, just time Marciana’s burst 2 for the shield and take cover when they start firing. May need some RNG for your unit to survived because you need at least 1 unit on each burst stage to trigger full burst again.
– There is no 4th phase for me because its gone.
Always remember to focus the summon port when its possible and use the cover.
Hope you can beat it too because this stage suck.
just did with Tia, Liter, Naga, Alice, Summer Anis. Alice have +60% ammo, manual play to destroy core before spawning any unit.
the conclusion to this boss is that without either modernia / dorothy you can not beat this stage. if you have lower cp you must have one of thoose two. and another way you want to beat this boss is to have enough higher cp to actually burst the core to prevent the hit count bs the boss does.
if not even one of the point i mentioned is within you category then you’re doomed to be stuck here for quite sometime. added the fact if you havent overcome the 160 wall it is naturally impossible to get higher cp than the recommended cp needed to kill the boss wothout modernia/dorothy
While I do think it’s possible to do this without Modernia, Dorothy, Red Hood, Noah, or Snow White… one thing I am certain of is that it is impossible to beat this without breaking through the level 160 wall. my team comp was Liter (200), Rapunzel, Diesel, Privaty, and Modernia (all 160). Even though I already have Modernia with 3/4 OL gear, my dmg was still short by about 13 health bars. It wasn’t until I grinded to level 200 synchro that I finally had enough dmg to destroy Mother Whale for good.
Diesel is enough to tank the master class raptures, bring a DPS Nikke with enough damage to break the core (I broke mine after tanking the master class raptures), and then deal enough damage to finish the mission. (If you can’t deal enough damage, then I’m sorry but you’ll have to grind for lvl 200 synchro)
I hope y’all get good luck in pulling nikkes, cuz this took a lot out of me and I don’t want the same thing to happen to any of you.
I really don’t get why people think this is so difficult, especially now. RH makes it so damn easy. If you have RH, Tia and Naga then you should have NO problem beating this thing, even on hard mode. You can use ANY L1 burst Nikke you want, as it’s irrelevant, and any secondary L3 burst also. (Use Liter if you have her) You really only need the three I mentioned. With RH L3 Burst along with Naga’s core DPS bonus, you can easily use RH to destroy the core, maybe even before the first wave of raptures spawn. After destroying the core, (might have been a glitch, but I doubt it) MW had less than 10% of its HP left. After that, just take cover when MW flies past and Tia’s taunt will absorb the damage from the lord raptures. EZ PZ.
WARNING: DO NOT EVER listen to advice given by whales, they don’t know what they’re talking about… they only know how to pay to win.
This boss makes me want to quit this game. it is literally impossible. I have some of the Nikke’s mentioned above, but not all of them and the ones I have are not fully upgraded, but I am still 70k over the requirements. No dice. I just get wiped. Have tried 10+ team compositions, full manual, etc. Nope. Guess I have to wait until I get 3 dorothy’s, 3 modernia’s and a gazillion others… Dumb boss
ahh… finaly i beat after around 2 weeks.Still 160 btw
my team : crown/borrowed liter/ my alice/borrowed alice(for lower deficit)/naga
I FOR THE LIFE OF CHRIST CANT BEAT THIS BOSS. I 100K OVER THE RECOMMENDED POWER AND IM STILL GETTING SHAT ON BY THE SMALL FRY AHHHHHHHHHH. AM I REALLY GOING TO BE STUCK HERE UNTIL I ROLL DOROTHY,RED HOOD OR MODERNIA????????????
Borrowed Liter
Ein 160
Quency: EQ 200
Elegg 160
Tia 200
I tried using Dorothy several times in place of Liter, yet she never seemed to be good enough at clearing the waves of enemies, causing wipes to happen no matter how many times I tried. I thought I’d be stuck for months on this, but instead, I ended up changing the strategy to one cycling the core, barely destroying it with the last bits of health remaining when its shield was up. I had to repeat enough times for the one cycle and keeping everyone alive, especially Tia for the master spawns and destroying the spawn pods for the final pieces of damage. I had about 5-10k deficit, but a lot of the units were decently boosted with only some T10 gear.
I strongly encourage those stuck on this mission to go for one cycle core strat as it seems to be the way to brute force the boss if you lack any of the recommended units.
After many try, just target the core (heart) at begining of the fight, and Mother Whale will not be dangerous. I used only Red hood for that
Hi there! I have never posted anything on reddit but because this mission was so damn hard I NEED to post this. I beat this boss at LVL 223 and I DONT HAVE DORO. I used Tia (x2 limit break), Naga (MLB), Noah (Not limit broken even once), red hood (x2 limit break) and Cinderella MLB. They all have orange gear no OL gear and all their skills were upgraded to what PRYDEWEN website recommends for the Bossing page. My key advice here is use red hood to take out the core thats on the under belly it took me 2 rounds of full bursts but once its destroyed the adds buff is gone and beat mother whale in 2 min!
*Sorry for the reddit mentions but I also posted my advice there. I spent a couple hours looking for advice and tried soooo many squad combinations and NOTHING was helping
This is ridiculous that now we can just bring Cindy and UngaBunga the boss out of existence bruh
i made early progress with smol white and modernia, picked up rh and that is great against the core [50mil dmg vs smol whites and modernias 6mil] shes not amazing anywhere else which is where i had problems. diesel could be the reason the small wave of raptures didnt nuke me on top of the bursts being able to kill the missle at the beginning. i think you should priotize clearing those missiles. then slot two bursters to kill the mini rapture waves. I think diesel saved me from the big nuke raptures but idk I mainly used her since she has massive stats from favroite item and MLB [she ddi heal 40mil]. the thread mentions being able to nuke parts but thats really unrealistic and I think what i really needed was the extra stats from synchro so ymmv there.
lvlv 227
diesel liter rh smol white and modernia
if you dont have modernia or smol white you need really powerful brust nukes to kill those waves before whale screams.
just cleared it on my alt at lvl 234. cindy and xmaiden wasnt doing it.
I used litle mermaid[wants your best mgs and ars], centi, a completely uninvested scarlet [worse than phantom most of the time], Wasuka [not super impressed but you need decnt mgs] and xludmilla as off burst dps mg
siren did 22m, scarlet didd22m, wasaka did 15m, and ludmilla did 10m
core is obviously siren and the team is built around getting as many bullets to proc her skill to actually do enough damage before the def reduction missiles lead the team to getting one shot. the nice thing about the comp is that i only manualed to actually kill whale and make sure you manually full cover when the big bad rapture wave spawns. on my main that team could kill them but really really struggled with the small fry so i think just having enough mg/ar/smgs to whittle those guys down while having enough dps to kill the whale is the secret to the fight. that comp was also able to destroy every missile while this comp just facetanked it
with the all bullet per second team comp the auto aim got a large enough of the missiles and small raptures that only the big wave was deadly which wasnt the case on my main which needed RH and alice to rip through whale and smol white and modernia on manual burst to get the small guys and missiles. RH can get most of the missiles tho. that comp could rip through the big guys so it was a big dps check at that point and just burst check that i had it ready for each wave.
with this comp it could be the stats, OL, or the units [obviously siren holds the whole thing together] that lets the comp tank some missiles just enough that as long as you get lucky enough with tanking some of the big rapture wave and letting the cover expire for the rest you can survive long enough to burst 1-3 times to kill whale wiht this comp. mgs seem pretty limited outside of pilgrims, events and collabs so ymmv there. Overspec mihara was made with siren in mind so thats a though. my main tried wiht smol white which was great fro her on x bullet skill for dealing with the smal fry and missiles on top of her burst. phantom with no investment might be worse than scarlet just because scarlet has ele weakness on whale. privaty might be ok for her stun idk. . liter is not sufficient so smgs seem very suspect.
tldr: siren can clear whale with mgs.
Just beat it with low power, was behind recommended by ~15k.
Team used: Crown, Liter, Alice, Raven, Naga. (order of team)
Kill core first and raven will wipe out the summons by the time 2nd burst comes back.
I’m not even a veteran player, started playing 1 month ago.
Hope this helps anyone.
for prev. comment:
Alice was lvl194 with 2 OL gear.
rest were lvl160.
Beat this hunk of a boss just now after grinding some attempts for a few days and trying out different teams.
Ended up with this composition with a cp deficit 7-8k under recommended(i think?) at 136,435
Tia LVL 175 – nothing special just skill 1 lvl 8
Liter LVL 200 – freebie from the campaign
Alice LVL 183 – 2 OL gear (1x charge roll)(NO MAX AMMO ROLL lol)(limit broken 3x)(Max skill 1 and burst)
Naga LVL 175 – limit broken 3x – Skills lvl 6
Scarlet LVL 175 – nothing special just skills lvl 6(my best electric nikke if i needed to finish off core before wave)
I had been dreading this fight every reset as it turned out to be a big wall for me having mostly invested in fire code nikkes lol. However, as I’ve learned, a deficit doesn’t mean you cannot overcome a stage with proper strategy. I had bumped around between my main campaign force which has 2 shotgunners(Seredorothy and Drake) to trying out a main force of electric nikkes, to a jank strat with Privaty. I could kill the core with the help of Privaty, but afterward I would usually lose a nikke and then not be able to deal with the master raptures later.
Tia and Naga help tremendously here as you can mostly ignore the bombs at the beginning and still keep most cover for when mother whale uses the Hurtle attack, thanks to the shields created. The damage boost along with Liter’s boost as well makes destroying the core within 15 seconds of the start possible with Alice. It may still have some health left over and at that point its integral to try and burst again asap to get the extra damage.
Strategy is spam shots at beginning with Alice to burst. Make sure fully reloaded at the beginning of full burst and then wail at the core. It probably will have some health left after, unless you have some max ammo up OL rolls on alice, if it does you can try to burst quickly again to destroy it, or just try your luck at damaging it before the code shield appears. I held off on bursting until the 2nd wave of raptures had appeared to wipe with scarlet after dealing with the core. After that, if youve kept all of your nikkes in tact(you may have to give this many tries to get some good rng or be quick to cover them) its the master wave and if your burst rotation is correct, alice should be back and she will chew through the lot of them. The few that remain dissapear and you are back dealing with mother whale. Unless you get unlucky or are fighting your last, it should be a cake walk from here.
Hope this helps ppl in the future who have trouble with this boss. Good Luck
Whoever design and make this stupid boss hope die eating by whale or get nighmare every night, the problem is this stupid boss also appear on each manufacturer tower and sometimes the nikke on each manufacturer can’t deal much dmg / doesn’t have screen wipe dmg nikke that’s when it’s getting problem.
