Update 90: Leviathan
If that beast ever comes back from the dead, I’ll show it the true wrath of a QUEEN!
Here we go, the last set of sea quests we can do for now.
Here’s the team I’ll be using for this one.
Gonna be going with a very defensive Limit setup for this one, since I don’t really trust Squire to do a good job.
But you spot a gigantic shadow approaching your ship at tremendous speed! That’s no ordinary fish!
Hoo hoo! Look at the size of that fish coming our- uhh, that’s way too big to be a Tanniyn!
The figure that leaps from the water is none other than the sea dragon from Ugarit!
It may not be a fish, but it’s a fine catch indeed!
The client steps forward and levels his spear! He looks as though he’s been ready for this the whole time! Following his lead, you draw your weapons and dash toward the sea dragon at the bow of your ship!

Leviathan is a bit of an interesting boss. It has a couple of strong elemental attacks, but more interestingly, it’s the only enemy in the entire game that has access to an accuracy debuff. And the penalty on that is rather steep, so it can’t really be ignored that easily. Since it’s not Leviathan increasing its own evasion, you can’t just Ad Nihilo the problem away. Though Prince/sses do have access to Inspire, which can dispel the debuff. Arbalists also have access to Pop Flares, which can be used to dispel the debuff, or prevent it from landing in the first place. And if you don’t have access to those skills, you can always make use of Unihorns, which will dispel debuffs on the entire party.
Plague is also the status effect to watch out for here, as Leviathan loves to go after infected party members with Overeat. Which will not only kill the party member, but heal Leviathan for a very large amount, undoing all your hard work. Tie Up is also really inconvenient to be hit by, but the binds it inflicts are not as much of a priority to get rid of compared to what Plague does for Leviathan. Hard Scale is also pretty annoying to deal with since it effectively neutralizes your physical damage dealers, but by now, you should know how to deal with enemy buffs.
Starting off, I buff up Rose and Charlotte’s offenses, and have Sidney put up Pop Flares as a safety net to stop the accuracy penalty from Fumes later on.
This battle is off to a good start, as Squire buys me a free turn.
The worst part is that I’m actually getting used to this.
Swim all you wish, you’ll fall soon enough.
Thanks for the cover. Now, get a load of this!
Aaaaand, it’s off!
Gonna take the time to Berserker Vow again. I don’t trust Squire to protect the party, so I’m using Aegis Shield.
Gonna have Susan debuff Leviathan for even more damage, and to stop Hard Scale in its tracks.
And another defense debuff, why not?
A flawless defensive formation!
...I can think of a few ways to get past it.
Shhh.
Yeah, definitely a good thing I broke out Aegis Shield, since Line Guard wouldn’t have been enough to save Rose and Charlotte.
Hmm hmm hmm, denied!
Ohoho, is that a weak point I spy?
Hey, don’t leave me out on the fun!
Gonna have Rose and Charlotte charge up for their big attacks.
Susan will prevent Fuming Snort from landing on the front row.
And I’ll have Sidney heal up Rose. Charlotte has Endure, so she’ll likely be fine if anything happens.
Well now Charlotte’s completely safe.
Have some regal protection!
I’ve been getting some real good setup turns.
Pills here.
Ahh, thanks a lot! But uh, you couldn’t have given that to Charlotte first?
Ehhh, she seems fine.
M-medic? Anybody? Please!?
I-I would appreciate some medical assistance!
Hang on, you’ll get your turn.
Time for Rose and Charlotte to unload their attacks.
Misery loves company!
Charlotte rolled all 10 hits here, and dealt a total of 7476 points of damage.
Okay, I really need medical assistance!
Mmph mmph mmph!
Rose dealt a total of 3963 damage with that Blade Rave.
A queenly reward for your troubles.
Ah, finally. Thank you, MEGAQUEEN!
That assault took off a good chunk of Leviathan’s HP.
Oh, this is gonna set me back. While Pop Flares can deal with the accuracy debuff, the back row doesn’t have Prevent Order on them.
Oh that’s just gross!
...Too little, too late, princess.
I’m a QUEEN, thank you very much!
And Squire spends the turn being useless.
Oh dear, I don’t like the way that sea beast is looking at me. Protect me, oh valiant knight!
...You incompetent fool!
SUSAN!
R-Rose, calm down. I didn’t see chewing, so there might still be hope for her...
Hey, why weren’t ya protecting us!?
...
Squire, you suck.
Really? You just did that?
Uhhh, ya’ll better work fast. That lump in its neck just got down to its stomach-
AAAAAHHHHH!
Oh goodness, that was quite the gastrectomy.
PWA! Oyyyyy... I’ll have to take a long, long bath when I get back.
Oh, Susan! You really had me worried there for a sec- I’m not hugging you while you’re covered in that.
...On second thought, maybe not.
Nothing too much to that fight. Just make sure you have a way to deal with Fuming Snort, since that can turn the fight in Leviathan’s favor.
You know, I was just wondering... What was it like being inside a monster’s stomach?
...Really Sidney? Really!? You really asked that!?
Uhhh...
But if you insist, I would be more than happy to divulge the horrific secrets of STOMACH ACID to you!
Oh, is that what happened to your hair?
Snrk. You know, you actually look kind of better that way.
Oh, hush.
Based on what you saw of the client’s skill, he should do just fine fighting in Yggdrasil.
Oh, and do pet the lizards and lynx. They’re quite harmless.
Yeah uh, do the exact opposite of she just told you. They’re anything but.
As everyone celebrates, you set sail toward the ocean city to accomplish the task at hand.
Sounds like he was quite frustrated about being stuck in Ugarit. His future will be much brighter. Ah, I almost forgot. He asked me to give this to you.
This shield reduces all elemental damage by 10%. Quite handy, and it only has 1 less DEF than her current shield.
Oh, and upon completing any of the sea quests after getting the equipment from them, he says this instead:
Another job well done. The chart’s nearing completion, and the ocean city’s restoration is nearly done.
Unfortunately, I forget to spend Rose’s skill point for a good while. Anyways, I tried to take on the 2nd sea quest, but I failed at it numerous times. So I decided to adjust my party’s equipment a bit.
Oh come on, I don’t need glasses!
Look, Rose. We’re getting kind of worried about you. You seem to be missing your attacks quite often.
Yeah, and you’re kind of bumping into a bunch of stuff- ooh! I think these’ll work! Why don’t ya take a look for yourself?
What the-!? Goggles!? Really!?
Oh, what’s the harm? I do believe they’ll- snrk, make you look better. Pfft.
Look, Susan, I don’t need you to be butting in right now.
Actually, I’m Cassandra. Susan’s behind you.
...Tch, fine!
Namely, upgrading Rose’s weapon and getting her some Target Goggles since she kept whiffing her attacks, even without the Fuming Snort debuff.
And increasing MEGAQUEEN’s speed a bit, since Leviathan keeps outspeeding her. Alright, now we’re sufficiently prepared to take on the next sea quest.
Toma again? Wow, that guy never gives up, huh?
You have to admire his tenacity for treasure hunting.
This is the team I’ll be taking along for this fight. Doubling up on Princesses may seem questionable, but Dezerte only really cares about the front row. So I’m bringing in Susan so the back row can be covered as well.
And here’s my Limit setup. I’m bringing along Aegis Defense since Cassandra herself can already handle the elemental attacks. As for why I’m bringing along Lucky Hammer, I’ll bring that up when it becomes relevant. So, let’s do this.
Then, you spot a gigantic shadow approaching your ship at tremendous speed! That’s no ordinary fish! This must be the beast you are here to destroy! With a quick glance, you and the client prepare to fight! The gigantic sea dragon leaps from the water, cloaked in waves, as if meeting you for the fight!
Wow, that thing’s belly healed fast.
No matter. We’ll just take it down again!
Round 2!
Instead of having Rose and Susan do anything, I’m having them defend. This is so they can survive the incoming attack, since I need to have Cassandra use Bunshin, and there’s no way for them to survive otherwise.
This should take care of the Plague component from Fuming Snort.
I can’t do this alone.
Don’t worry, help has arrived!
Ouch! Ooh! Hot hot hot!
I’M ON FLAMES! 
Now I’ll have Rose use Berserker Vow.
MEGAQUEEN will buy the team a free turn with Aegis Defense.
While buffing Rose up.
And the Cassandras will restore their own TP, since I’m expecting this battle to take a while.
Eh, it’ll do.
And Leviathan just wasted its turn.
I’ll have the Cassandras defend the party while Rose keeps on getting buffed up.
Your waves are nothing against my shield!
If you were wondering how I guessed what Leviathan would do perfectly during that portion of the fight, I’m very familiar with how the beginning of the fight plays out and what I have to do to deal with it due to several previously failed attempts and the way the game’s RNG works.
I’m not super reliant on healing items for this fight since Toma’s pretty good at keeping people topped off.
Though at this point in the fight, I had no idea what Leviathan was going to do next, so I only had one objective in mind. Which was protecting Rose to ensure that I could actually kill Leviathan.
Oh, don’t you think I forgot where your weak point was!
Alright, let’s see how much damage Rose deals with her new sword once she goes to town on Leviathan.
Man, does Faye appreciate how much you do for us?
Not when all this started, but I think she’s coming around on that.
Seriously, it’s really not surprising that the Anti skills weren’t in EO4 after this.
Don’t even think about eating Susan again!
Wow, what a difference an equipment upgrade makes. She dealt a total of 5966 points of damage there, and that was only with 4 hits.
After another Charged Blade Rave, Leviathan’s health is pretty low. So now is when I’m gonna try to go for its “conditional” drop.
Alright, so Leviathan’s 3rd drop isn’t really a conditional. It’s just a random drop with a 20% chance of dropping. Kind of like Ghost Ship and the whole Navel Ram deal, only Leviathan’s drop has a higher drop rate. But remember that we got the Lucky Hammer Limit from these Sea Quests, which forces any enemies killed with it to drop all their items, no matter what. So we’re meant to use Lucky Hammer to snag the drop, but Leviathan doesn’t make it easy for us. For one thing, it’s resistant to Strike attacks, and Lucky Hammer deals Strike damage. The other thing to note is that if anyone happens to catch the Plague while Leviathan’s HP is below 11%, Leviathan will cast Overeat on them. Normally that wouldn’t be a problem, since it would be easy to kill Leviathan at that point. On the other hand, specifically killing it with Lucky Hammer, which has negative priority, is much harder to pull off because of that. Yeah, they basically implemented a whole routine just to make snagging the Tsunami Fang even harder. Thanks, Atlus. 
So my plan is to basically weaken Leviathan with an uncharged Blade Rave and-
OH COME ON!
How does anyone’s breath get that cloudy!?
I can think of a lot of reasons. Though none of them are pleasant.
Fortunately, I came prepared for this. I brought along Unihorns since I don’t have Sidney with me, so that will dispel the accuracy debuff.
I grant you all, the gift of sight!
But I’m the queeeeeeeen!
Um, whoops. I’m sorry about that.
Hey, at least you weren’t wasting your time doing nothing.
Now this should weaken Leviathan enough-
...Ah son of a gun, I overestimated how much HP it had left. This really sucks, if I just used Lucky Hammer, I would have gotten the drop.
You just HAD to get in one last potshot on Susan, didn’t you?
I. Um. What? I failed to snag the drop with Lucky Hammer. Yet I got the drop anyway due to chance. Okay then, I’ll take that.
The client steps forward to collect some of the sea dragon’s blood.
Are you done yet? We need to be heading back soon.
It seems they got what they came for. You set sail for the ocean city to report your victory and return the clients to port.
...
We went through all that, just to cure his cavity?
At least he got some practical usage out of it?
Look at it this way, we may have a promising career in dentistry after this.
Hmm, the queen of teeth. Not an exciting title, but I’ll claim that throne anyway.
I suppose his greed is one thing, but at least he must be happy to have a stiff drink without pain. This was left for you from the client. I guess she’ll be getting new armor soon.
Nothing particularly special about this piece of equipment, but it does provide a decent boost to defense.
Now as for the next Sea Quest, unfortunately that one also had several failed attempts. There wasn’t really much I could do with the team selection I had, so I had to break out the secret weapon...
Accessorizing. Yes, this will do nicely. The Slice Amulet will help with Overeat, but it won’t save anyone if they have the Plague while Overeat targets them. The other 2 amulets are for Leviathan’s elementals. Tie Up doesn’t really do much damage wise to be worth worrying about. This won’t completely snap the fight in half, but it gives me quite a bit more wiggle room. Look, the other alternative was grinding more, and I didn’t feel like doing that!
Since I already completed this Sea Quest through the exploit, I won’t have to do any of these fights a 2nd time for the equipment.
Is that thing still alive and kicking?
Probably. We should finish it off this time.
This is the team I’m bringing along for this fight. Susan has access to buffs, and can prevent anyone from contacting the Plague in the first place. Sidney can preemptively deal with Fuming Snort, and will serve as our damage dealer.
Offense isn’t a huge concern for me in this fight. I’m more concerned about surviving it, so these are the Limits I’m taking along.
After a few moments, the captain of the pirate ship offers an audacious smirk and points to the distance. You turn around to find the sea splitting before you, revealing a dreadful sea dragon!
Why are these sea monsters always so persistent?
Who knows? But if they want more beatdowns that badly, I’m all for it!
This must be the beast you are here to destroy! You draw your weapons and prepare for the onslaught!
Round 3!
Starting off by buffing up the damage dealers in this party, and having Sidney put up Indomitable. He needs that Limit more since he’s pretty fragile. Susan is durable enough to live through Leviathan’s attacks more easily.
You? Kill me? I’d like to see ya try!
You might have noticed that Leviathan always went for Fumes on the 1st turn, and that any NPCs that could block it would always do so. Yeah, that’s due to the quirk of the RNG in this game since I tackle these sea quests in separate sessions.
Sumitomo’s damage output with Pincushion is very lacking, so you’re better off bringing your own damage dealer for this fight.
Also, there’s a prophecy in action.
Yer gonna love this! Trust me. And I think I just broke my neck.
The other benefit to using Berserker Vow in this fight is that Taquion is more likely to defend the party if Leviathan uses an elemental attack with someone at low health.
Stacking more damage multipliers.
Marked for death!
Well, let’s see how Sidney does despite Leviathan’s Pierce resistance.
OH COME ON! 
No.
Ho ho ha ha!
Look lively!
Decent damage despite Leviathan’s Pierce resistance. Though the Double Action proc was definitely helpful in boosting the damage done.
Yeah, if it wasn’t for that, Leviathan would be dead right now. That’s the power of Arbalists for you.
Now’s the time Leviathan’s gonna start breaking out Fuming Snort, so I’m gonna start preparing for that.
You have nothing to fear with me around!
Speak of the devil.
Ya really gotta work on yer reaction times.
Zip it.
Hee hee hee! It’ll take more than that to throw off my aim!
Thank goodness for Proper Form.
Leviathan’s pretty close to dying, but with that Fuming Snort debuff on everyone, there’s a good chance that Sidney will miss his next shot.
Time to bust out the flares.
Your pathetic plague ends here!
Ooh, looking a little cloudy here. Let’s clear that up!
You’re only delaying the inevitable.
Just let me kill you already!
And I can do this allll day!
This is just kicking me while I’m down.
At the very least, Leviathan can’t take much more of this.
I will NOT be your personal snack this time!
Might as well use this since MEGAQUEEN’s not looking too good.
Oh, maybe that wasn’t necessary.
YEEOOOW! Hot hot hot, oof! I’m okay!
Or maybe it was. And it turns out that Flame Amulet wasn’t enough to save Sidney. At least he had Indomitable up.
That wasn’t enough!? I thought I had that for sure!
If Leviathan hadn’t used Overeat all those times, it would be dead by now.
Ohoho, does it hurt to see your efforts undone so easily? Does it!?
Sheesh, what’s got you so worked up?
A queen does not forget her grudges so easily.
At least this fight’s pretty much over.
Ah hee hee hee! That ain’t gonna save ya now!
I already had Pop Flares up, so all Leviathan accomplished was dispelling an uneeded accuracy boost.
Good riddance, you stupid sea beast!
...I really didn’t need a second Tsunami Fang there. But okay.
Anyways, Leviathan isn’t too bad, the only real problem is Fuming Snort. If you have a way to deal with that, you can deal with it fairly easily.
The pirates return to their ship after thanking you... After seeing off your dignified allies in war, you set sail toward the ocean city to report in.
Learning about others is the best way to learn about yourself. The marines will have to work harder. But you all did well, too. The pirates delivered this for you.
Increases resistances to all binds by 20%. To be honest, I’d rather increase someone’s bind resistance to one type of bind by 50% instead of having this low all around resistance increase. If binds are really a problem for someone, most of the time it’s only one specific kind of bind that shuts them down. Anyways, let’s see what Leviathan’s drops make.
We still don’t have the weapon the Dragon Fang unlocks, since there’s a drop from a 6th Stratum enemy we need to take down first to get it. But let’s see what the Tsunami Fang unlocks.
It makes the Trident, which is the ultimate Spear. Which only Cassandra and Fang can make use of. Not really a super great ultimate weapon, but at least it comes with some defensive forges. Though since I got 2 of them, I guess Cassandra and Fang could be trident buddies or something like that.
And that’s it for all the Sea Quests for now. We’ll tackle more of the 6th Stratum next time.
