MMM - Gorgeous Godly Goddess Gaslights Gamers, Generating Guileful Good-Times Gregariously, Golly! (Summer 2025 Part 3)

PRAISE BE! THE CURSE IS BROKEN!

With a base NP gain of 0.59% and a BAAQQ card deck, Tiamat’s 3-hit Arts cards finally buck the trend of every other Servant this Summer, resulting in a base Arts gain of 1.77, only slightly above average. While her Arts cards aren’t anything impressive, the higher base NP gain she packs means her 5-hit Quick cards are superb for NP gain, her Busters are similarly decent, and for what feels like the first time in forever, we have a Servant with an Extra card that provides good NP gauge.

It doesn’t stop there, though. With Tiamat’s primary focus being Quick cards, it’s natural her star generation is excellent. The 5-hit Quicks speak for themselves, but her 4-hit Buster and 5-hit Extra card are also good for star generation, even if she’s not the greatest out there for star generation. Combined with her Archer star weight, Tiamat has little issue producing critical stars then using them…though maybe you don’t want a support to do that. Reines knows the pain too well.

Skill 1

First on Tiamat’s skill lineup is Azure Summer Clothes. This team buff skill provides a trend-setting dual-card buff for all of Tiamat’s allies, granting 20% Quick and Arts Booster for 3 turns, as well as 1-time Buff Removal Resistance and 1-time 200% NP Overcharge bonus for the same duration.

The buffs on this skill are very straightforward, but they’re also simply great. The card boosters both support Tiamat’s primary card types and that of her allies, and the NP Overcharge boost is incredibly powerful, depending on your team composition. Being able to kick off a Space Ishtar farming loop with 300% overcharge on her ramping damage steroid is great, for instance, but I think the potential of the buff speaks for itself.

In addition, Buff Removal Resistance on a Support is incredibly powerful for difficult content. No matter how game-warpingly powerful Castoria is, she can still get absolutely rinsed by a NP with Buff removal before damage, or the classical annoying Buff Removal upon gauge break that makes so many fights feel unpredictable. Tiamat provides a means to safeguard against that, and even if Tiamat can’t provide the buffs necessary to keep the time’s offensive might or survival going, she can at least ensure the supports’ buffs that are needed stay online until they run out. It’s not without its weaknesses, though, such as bosses who do buff removal each time they attack, something that’s not uncommon, so it’s not an absolute, either.

The base 9-turn cooldown on this skill is pretty long, but it does have some exceptionally good benefits. Getting the cooldown reduction append skill on Tiamat will probably be key to compensate, but it’s hard to argue with the power this skill provides, even with the long cooldown.

Skill 2

Continuing on, we have Housekeeping Virtuoso. The essential skills of any Momm- I mean, Big sis- I mean, childhood friend, this skill matches the lore by having the all-essential 50% gauge charger packed in it.

But wait, Tiamat is a support, so she also gives 30% gauge charge to her other allies, resulting in a hefty total 110% gauge charge in one skill, meaty. She really isn’t content to stop there, though, so this skill is also a Charisma skill, providing a 20% Attack buff to the team for 3 turns, and a 2000 HP heal on use for good measure.

So far as supportive gauge chargers go, this is one of the best in the game without any strings attached. It essentially has the same buff values as Castoria’s Charisma skill, with an extra 20% gauge to Tiamat herself and the 2k heal on top. Having the significant personal gauge charge is especially convenient, since Tiamat is designed in a way that getting her own NP out early is to your benefit. The only real flaw to this thing is its long 9-turn cooldown, reflecting the overall power with a hefty waiting period.

Skill 3

Last for Tiamat’s skills is Summer Mirage. Compared to the prior skills this is lacking in sheer meat, but is no less important.

This is a straightforward team-wide buffing skill that provides every ally an 8 Critical Stars per-turn buff, +50% Critical Damage, and +10% NP gauge per turn for 3 turns. So in total, it’s 24 Critical Stars every turn for its period, while also boosting the team’s critical damage significantly, and providing a total of 30% NP gauge for everyone over that period.

While usually gauge chargers that last over time are inferior to direct gauge charge, Tiamat is in an interesting position where she just does both of them, and the fact she’s geared to support Quick / Arts Servants means that gauge charge will often be useful - there’s an issue with Buster Servants who get gauge per turn or off of their NP’s where a stray 10% or 20% gauge doesn’t meaningfully contribute to their looping capabilities, and ends up being wasted due to how inflexible Koyanskaya farming setups are - with only 50% gauge charges available and the loop often dependent on re-using a gauge charge skill.

However, for Quick / Arts farming, a small 10% NP gauge every turn can change the whole setup, allowing you to run a more aggressive CE or Mystic Code choice, or just generally making a loop more consistent (since sometimes even small damage variance changes the amount of NP refund from Overkill, meddling with the farming loop). And in difficult content, this skill is even better, getting the whole team’s NPs ready quicker, while also essentially solving star supply for its duration and providing a notable offensive boost.

No matter how you slice it, it’s great, and the less-impressive buff lineup means it has a more bearable 8-turn base cooldown.

Wrapping things up for Tiamat’s kit is her NP, Nammu Marineheart. There’s truly no greater superpower in this world than manifesting the anime trope of a childhood friend-type romantic interest showing up randomly in S2 despite never being mentioned before.

As a Support NP we only really have to talk about the benefits of its effects, but boy are there a lot of them.

This is a Quick NP, providing the whole team with a plethora of buffs on use. First and most importantly, it provides a 1-turn Invincible buff to the whole team, meaning Quick-focused teams finally have a dependable defensive cooldown to rely on.

Now, you might wonder, doesn’t OG Skadi also have a team Evasion on her NP? Did Rath just forget? No, I didn’t, I’m just using this part of the MMM to vocalize that past Rath heavily overrated Skadi’s capabilities in difficult content, not realizing that somewhat-good Arts card NP gain on a Caster with no personal gauge charge (because like hell you’re throwing that 50% gauge charge on her outside of a dire situation) is not enough to have a defensive support NP up when you really need it, then against spamming it in the way Castoria can.

And that’s where the difference lies. Not only does Tiamat have better regular card NP gain behind her (factoring in her Arts/Quick boosters), but she also can crit more often for the bonus NP gain due to her Archer star weight and easy star generation, AND she gets a total of 80% gauge charge to benefit from at no expense to others. As a result, Tiamat gets to not only use this team Invincible buff when you need it, but regularly at that, getting a significant chunk of her NP gauge back from a single Arts or Quick crit.

That’s just the first part. Tiamat also provides the team with a hefty Debuff Resistance buff for 3 turns, scaling up to 100%, more or less immunity, at NP level 5. Tiamat herself already is incredibly durable against debuffs, but extending that to her team is also fantastic. In the rare fights where enemy debuffs are debilitating, such as the Aphrodite fight in LB5.2, I’ve brought Medea Lily in a normal offensive team simply because her Debuff Resistance buff off her NP is that good for ignoring debuff-based mechanics. Tiamat can essentially do the same thing but, well, actually having good skills and all the other parts of her kit, which is incredibly useful for shrugging off similar mechanics.

With those aside, we get to the real meat - Tiamat also provides both 30-50% Quick and Arts Up to the team for 3 turns, and 50% Critical Damage Up for the same duration, scaling significantly with Overcharge, as it goes up by 25% with each Overcharge level. At NP1 Tiamat using her NP is providing a total of 50% Quick / Arts Up, and 20% Attack Up, which is equal to Castoria’s own offensive buffs, and a little behind Summer Skadi’s.

Now you can argue that’s an unfair comparison, as nobody really uses Castoria or Summer Skadi’s own NP’s before their offensive Servant’s to boost the damage on the regular, but my counterpoint would be that Castoria has a 30% self gauge charge, and Summer Skadi has none to her name. If Tiamat deploys with a 50% gauge CE she can NP turn 1 without any “waste” of NP gauge, and she also benefits from the 10% gauge per turn buff in drawn out fights, so NP’ing with her is significantly easier than either in both farming and difficult content. It might cost some time to see the animation, but if it enables a farming loop that wasn’t doable otherwise, who cares?

Naturally, this buff lineup gets pretty absurd when examined outside of a farming context. By just blowing all her skills at once, the combo of 50% Quick / Arts Up, 20% Attack Up, +200% Overcharge boost, and 150% Critical Damage Up (factoring in the Overcharge boost on Tiamat’s own NP) is well beyond what any other Servant in the game can give, especially on the whole team for 3 turns. Summer Skadi might hit similar numbers, but all her buffs only apply to one Servant, and the Critical buff is awkwardly only applied to Buster cards, while even Merlin’s famous Hero Creation’s Critical buff only lasts a single turn. Tiamat’s capability to provide the strongest team offensive buff package in the game and also spam said package, if you’re using regular cards in chain, is absurd.

…Oh, and all the buff numbers go up by a decent margin with NP level, meaning what I’ve said thus far is simply emphasized further for a NP2 or higher Tiamat. The only flaw to this NP, really, is the fact it’s Quick. Her inability to contribute to a full Arts chain of NP’s and potentially reap the extra 20% gauge to push her or her allies into another Overcharge level will come up fairly often, but on the flip side it does let her prop up a Brave chain Buster card crit in combo with an Arts NP, or provide bonus critical rate to later cards in the same chain.

With a base NP gain of 0.37% and a BAAAQ card deck, Jeunesse Crane returns us all to the normal agenda with her 4-hit Arts card producing a base Arts gain of 1.62 after her passive +10% NP gain buff is factored in, dead on average. As you might expect from such an awful base NP gain, her other cards are absolutely dreadful for NP gain, but thankfully she has 3 of her Arts cards to work with, so it’s not as much of a flaw as it seems.

Jeunesse Crane’s incredibly high star generation rate due to her passive means she is pretty damn good at star generation, even when using her Arts cards. Her hitcounts across the board are solid so she’s very capable of providing stars to the team, which in turn can help compensate for her flaws in NP gain.

Skill 1

Starting off Jeunesse Crane’s skill lineup is My Teenage Emotional Distancing Can’t Be This Cute!

…Wait, that sounds wrong. How about “My Teenage Emotional Distancing Is Wrong, As Expected”? Nope, it still doesn’t work.

At any rate, this skill is a package of team buffs, providing 20% Arts Up to the whole team for 3 turns on the offensive side of things, as well as a hefty combo of 1-time Debuff Immunity, 1-time Evasion, and 30% Critical Resistance for the same duration.

The Arts buff is already appreciated, bolstering Jeunesse Crane’s main card type and assisting the team’s damage output / NP gain, but the trio of defensive buffs are pretty damn great, allowing the team to evade a lethal NP for a turn, soak a single wave of debuffs, and just avoid criticals for a long period of time. Even if used prematurely to get the offensive Arts buff, those buffs will get their full value over the duration.

It’s nothing exceptional, but it is a very good supportive skill that doubles up both offensive boosts and team defense, and even the 8-turn base cooldown is solid given its power.

Skill 2

Next up we have Thinking of You, The Song of Clothing. This continues Jeunesse Crane’s supportive trend, providing a rare 20% team gauge charge on an SR Servant.

That isn’t all to this skill, though, as it also provides the team a 20% NP Strength Up buff for 3 turns, and a combo of buffs that leads into Jeunesse Crane’s main gimmick. After all, you thought the gaslighting and girlbossing ended with just Tiamat this Summer?

No, in fact, Jeunesse Crane wants her whole team to get in the enemy’s head, providing a +40% Mental Debuff Success Rate buff to the team, as well as a 30% Effective Damage buff against enemies with a Mental Debuff for 3 turns. It’s a given that Jeunesse Crane herself will have some Mental Debuffs at her disposal, but for the record a Mental Debuff is essentially just Charm, Confusion (The debuff that lasts for multiple turns and might Skill Seal the afflicted target each turn), and Terror (same as Confusion, but for Stun, and it goes away once it applies the Stun once).

But putting the Mental Debuff gimmick aside, this is a great skill to have, providing a useful form of gauge charge on SR deployment cost, as well as a second team offensive steroid. With just these first two skills Jeunesse Crane is pretty solid as a supportive option, and the 8-turn base cooldown of this skill means she’s not going to be waiting too long on reapplying either of her skills thus far.

Skill 3

Wrapping up Jeunesse Crane’s skill lineup is I Won’t Lie to Myself This Summer, completing the trio of awkwardly-named skills.

This skill is Jeunesse Crane’s first source of Mental Debuffs, applying a pretty-consistent 60% Charm to every enemy for 1 turn, which is essentially a 100% chance (before enemy Debuff Resistance) once you factor in her own buffs. AOE Charm or Stun with no conditions is always great for difficult content, though the circumstances can change how effective it is, since often bosses have some degree of debuff resistance, if outright immunity to the debilitating debuffs like Charm.

Well thankfully that’s not everything to this skill. It also doubles up as Jeunesse Crane’s selfish gauge charger and NP steroid, providing both 30% gauge charge and a 30% NP Strength Up buff for 3 turns upon use. This makes her one of the few SR’s present in the game to have access to a 50% gauge charger or better with no strings attached, and getting that paired with even more offensive buffs to put to use is a heck of a combo.

Since this skill also turns on Jeunesse Crane’s Effective Damage buff, it’s essentially an extra +30% damage for 1 turn off the Charm, so this is undoubtedly a potent skill. It even comes with an 8-turn base cooldown, shocking given the fact it’s an AOE Charm - those types of effects usually have 9-turn cooldowns.

Bringing the entirety of Jeunesse Crane’s kit to a head is her NP…Kagerouken. I’m just gonna call it Kagerouken. Even translating its name was annoying, so I’m shortening it.

This is an Arts AOE NP, so I’ll get into the looping numbers as it comes, but this is packed with a fair few effects we should get into.

Before dealing damage, this NP does a lot of things - it provides a 10% Arts Up buff to Jeunesse Crane herself for 3 turns, scaling with Overcharge, removes all Offensive Buffs from the enemy, then also applies Confusion on them for 3 turns.

While Offensive Buff removal is by far the least useful, it’s at least something to her name, and more importantly the Arts Up buff before damage is a ramping NP steroid that also boosts her NP refund, while the Confusion debuff immediately turns her bonus Effective damage online before hitting with her NP’s damage.

Speaking of which, Jeunesse Crane then does her damage, lastly applying the oh-so-rare 20% Critical Resistance Down debuff to targets struck for 3 turns, provided they’re not part of the Crane-protected trait assembly, being a Summer Servant or Child. During this specific event you probably won’t see the debuff applied much, but outside of it you basically only have to worry about Child Servants, which is a very finite sum of Servants.

At any rate, the effects on this thing are pretty good, but let’s inspect the damage and refund. With her own buffs active, assuming she’s landed a Mental Debuff on the target (which is very likely), Jeunesse Crane is doing 23k damage neutral, which is pretty damn high for an SR Servant. In addition, her baseline refund off her NP is 19%, which is more or less typical for an Arts AOE farmer.

Putting that into practice, with the standard 50% gauge CE and double Castoria setup, she’s more than capable of doing a 3-turn loop, and her damage output comes out to 56k damage neutral on wave 1, 81k on wave 2, and 106k on wave 3. Not a particularly impressive damage output, but it is enough to manage Alter Ego class advantage farming in general.

But can she run Black Grail? I…believe so? Jeunesse Crane’s refund isn’t the greatest out there, so she does require a battlesuit swap support as good as Ruler Da Vinci or better to tag in and bolster her, so I’ll go through the damage output presuming that. In such a setup, Jeunesse Crane will be doing 103k damage neutral on wave 1, 125k damage on wave 2, and 160k for wave 3. While not outstanding, it is enough damage to function as a universal farmer outside of 90++ farming nodes, or simply elevate her normal class advantage farming significantly.
