Lore

"Let that twilight burn!"

Laevatain is a Rhodes Island operator who joined Endfield at the Endministrator's direct recommendation. Under the framework agreement between the two companies, she serves as an operator directly under the Endministrator's command.

Before joining Endfield Industries, Laevatain roamed the world alone, pursuing a goal she could call her own. Because of that journey, and her formidable skill in solo combat, people often mistake her for "someone you can't talk to." In truth, the opposite is closer to reality. It's only that her earnest, forthright nature sometimes comes across too strongly, giving rise to misunderstanding.

At times, though, she speaks in ways that confound others, often circling back to the subject of "memory," as if she were purposefully trying to separate herself from who she is. She often wields flames, yet craves ice cream just as much. To her, maybe that contradiction feels perfectly natural.

Review

Laevatain is a 6-star, Sword, Heat Striker that mainly utilizes Ultimate as her core damage window. Upon use, Laevatain's Ultimate enhances her Basic Attack and Battle Skill for a duration of 15 seconds. What balances this Ultimate is its incredibly high cost, which is 3–4 times as high as that of other characters.

Generating so much energy naturally isn’t easy, but Laevatain’s Talent and Battle Skill solve this. With her talent, when doing a Final Strike or Finisher on an enemy, Laevatain consumes Heat Infliction on all enemies and converts it into a special stacking resource. Upon reaching 4 stacks, her Battle Skill is enhanced to deal more damage and generate absurd amounts of energy. Because of this, Laevatain’s teams and playstyle focus on building and consuming Heat Infliction to enter Ultimate and maximizing damage during its duration.

Talents

Despite being an Ultimate-focused operator, Laevatain would never get to use her Ultimate if it weren’t for her Talents. Laevatain’s most important talent is Scorching Heart, which causes the controlled operator’s Final Strikes/Finishers to absorb Heat Infliction from nearby enemies, converting them into a stackable resource for Laevatain called Melting Flame that stacks up to 4 times, each lasting 20 seconds. Melting Flame stacks are indicated on the left side of Laevatain's HP when she is the controlled operator and on the bottom left corner of Laevatain's icon. Upon reaching 4 stacks, Laevatain gets to ignore a percentage of enemies' Heat Resistance and enhance her Battle Skill.

Info

Note: Laevatain also absorbs Heat Infliction from enemies that are defeated, avoiding wastage.

Laevatain’s other talent is Re-Ignition, which grants her a massive Protection buff and heal over time for a short period after she drops below 40% HP, acting as a sort of cheat death. This Talent has a long cooldown, but it will definitely save you at least once from death or a close call per encounter.

Battle Skill

Laevatain’s Battle Skill is the main way she generates enough energy to fuel her absurd Ultimate cost. Her skill comes in two different forms; a standard version and an enhanced version. The standard version deals underwhelming damage, generates no additional energy, but does grant Laevatain a stack of Melting Flame. The enhanced version consumes 4 stacks of Melting Flame, deals far more damage, and generates a whopping 100 additional energy while also forcibly applying Combustion for 5 seconds, immediately enabling her Combo Skill trigger.

The standard version is rarely worth using over other characters' Battle Skills that applies Heat Infliction, as those can trigger other characters’ combos and enable other synergies, all while still getting the same Melting Flame stack. The enhanced version, on the other hand, is the backbone of Laevatain’s energy generation and should be the focus of your entire team composition, as reaching it faster means faster Ultimate access.

Last but not least, Laevatain’s Enhanced Battle Skill also becomes further enhanced when using it during her Ultimate, something which may seem wasteful as she cannot generate energy during her Ultimate, but is actually fine to do. The reason is that even against a single target, Laevatain and her team can usually generate enough Melting Flame to reach 4 stacks twice during an Ultimate as long as there aren’t any interruptions. As her Ultimate makes it so that only heavy-hitting enemy attacks can stagger her, this isn’t too difficult to achieve.

When cast during her Ultimate, it also has the added benefit of pausing its timer, meaning that it does not lead to Laevatain getting fewer Enhanced Basic Attacks as a result. How many Enhanced Battle Skills are used during Ultimate often boils down to the team rotation and whether or not Laevatain can be at or near 4 stacks by the end of it, so as to allow her to build energy back up quickly to cycle back up to another Ultimate as soon as possible.

Info

Note: In multi-target scenarios, you can easily apply and absorb Heat Infliction from many enemies at once, allowing for far more Melting Flame stacks and the possibilities of many more Enhanced Battle Skills.

Combo

Laevatain’s Combo Skill is incredibly important to use whenever available. The reason is that it generates a Melting Flame stack and grants her 25/30/35 Ultimate Energy on use (depending on the number of enemies hit), both of which are pivotal in accessing her Ultimate in a timely manner. To trigger her combo, the team must apply Combustion or Corrosion on an enemy, something Laevatain can achieve herself with her Enhanced Battle Skill, but definitely isn’t reliable or frequent enough to match its short 10(9) seconds cooldown.

To get around this, Laevatain requires the help of her team, so you’ll either need to pair her with allies that force apply Combustion/Corrosion or trigger it naturally through Arts Reactions, typically at the cost of some Heat Infliction. This may sound like a negative, but is something that should be kept in mind when playing with Laevatain as her Combo Skill generates massive energy and 1 stack of Melting Flame for her. This means that extra Heat Infliction can instead be either used to make Corrosion to further boost her damage output or to stockpile for her next Enhanced Battle Skill cycle.

Just like Laevatain's Battle Skill, her Combo Skill will also pause the Ultimate timer, meaning that it can be used freely during it.

Ultimate

The main damage window in Laevatain's kit is her Ultimate. It costs 300 energy, lasts for 15 seconds and upon cast will forcefully make her the controlled operator, but you can still change the controlled operator after cast. Her Ultimate will also enhance her Basic Attack and Battle Skill, giving a massive damage boost to both and changing her Basic Attack to a 4-sequence string with huge AoE swings. The 3rd sequence of her Basic Attack will also apply 1 Heat Infliction.

It is also important to know how her Ultimate timer works. 15 seconds may feel short, but there are ways to extend this with the help of timestops. Laevatain's Battle and Combo Skills will stop the Ultimate timer so it’s fine to use them freely and integrate them into rotations. Perfect Dodges and other teammates' Ultimate cutscenes will also briefly stop Laevatain's timer. However, the stops from these Perfect Dodges are very minimal, so it is more worthwhile to try and minimize unnecessary movements and let Laevatain do as many Basic Attack sequences as possible during her Ultimate state. Without any optimization like animation cancelling, Laevatain can easily get 4 Basic Attack sequences yielding up to 4 Heat Infliction stacks to have her Enhanced Battle Skill ready to use when her Ultimate runs out.

Info

Note: Laevatain cannot gain any energy while her Ultimate state is active. She also cannot use Finishers on Staggered enemies while her Ultimate state is active, make sure to time its usage and/or swap characters so as to deal with this.

Gameplay

Laevatain’s gameplay is incredibly simple:

Generate as many Heat Inflictions as possible, then absorb them with Final Strikes or Finishers to accumulate Melting Flame for Laevatain.
Keep her Combo on cooldown as often as you possibly can by taking advantage of her Battle Skill and spacing it out with allies’ abilities that can forcefully apply Combustion/Corrosion, or by triggering the Arts Reactions manually.
Once at 4 Melting Flame, use Enhanced Battle Skill to generate energy. Depending on the level of Ultimate energy gain, you’ll often have enough to use Ultimate after 2 casts.
Make sure to align ally's buffs and be aware to refresh the buffs before and during Laevatain's Ultimate to get the most damage out of her Ultimate state.
To get her Ultimate back faster, you can also leave out 4 Melting Flames for Laevatain to use when she gets out of Ultimate state, but expending them while in it for higher burst damage can at times be best.

Depending on the team you’re playing, there will be even more optimizations. To learn more, check out our teams and synergies section.

Optimizations

Although Laevatain can only get 4 full enhanced Basic Attack sequences with her Ultimate, by Dodge cancelling out of her Basic 2 after the first hit, as well as after her Final Strike, it can be possible to fit in 5 full enhanced Basic Attack sequences instead. But be careful, as cancelling the Final Strike too quickly may result in it not absorbing Heat Infliction stacks!

Energy

Laevatain’s Ultimate Energy regen is critical to playing her effectively, so understanding how much you need in certain scenarios is incredibly important when considering what Gear Sets to use on her, specifically whether or not you can give up Ultimate Gain % for more damage and if that trade-off is worth it. The challenging thing about her energy though, is that it changes based on the amount of enemies you’re up against, the amount of Battle Skills your team uses and the amount of Combos per Ultimate you’re aiming for. Against single enemies, Laevatain generates less energy and may want some Ultimate Gain if your goal is the fastest possible Ults. Against multiple enemies though, she gains bonus energy and is less likely to need it unless you’re trying for large breakpoints that involve skipping Combos or Battle Skills.

Below is a collection of tables showing how much energy Lae gains at 0 Ultimate Gain % plus various other breakpoints, in order to show when energy may and may not be needed.

Info

Note: Using additional or fewer team Battle Skills will grant more or less energy, potentially fixing or compromising certain rotations.

The charts below assume aiming for the minimal possible actions to highlight the cases when energy makes a difference.

In practice, meeting such breakpoints may not always be an obvious improvement, as SP Recovery can be a limiting factor. It's important to balance out Laevatain’s Ultimate use with application of teammate buffs/debuffs, which can slow down rotations. Players are recommended to evaluate whether meeting a breakpoint would meaningfully condense the rotation for a given team (e.g. if getting Ultimate in only 2 Combo Skills instead of 3 is a benefit).

Ability	Uses	Base Energy
Enhanced Battle	2	213
Combo Skill	2	50
Team Battle Skill	4	26
Total	289
Total (12.3% UG)	324.5

At 2 targets, a new breakpoint opens up for the energy build, which may be useful, as you no longer need 2 Combo Skills and can get away with 1 instead. In many cases, two Combos may still be used regardless, but there is a potential for optimization present.

Best Weapons

The percentages show the performance of the weapon based on calculations, but in some cases, some Weapons might provide additional QOL that can't be quantified and it would push that weapon ahead of others in the priority (and in those cases, we would put that weapon higher).

The solo percentage shows how the weapon impacts Laevatain performance if you look at their damage in the vacuum, while the team percentage shows the impact of the weapon when taking into account full team, including buffs etc.

Solo 100.00%

Team 100.00%

Forgeborn Scathe (P0)

Laevatain's signature is definitely her best option thanks to its passive Intellect, ATK%, and Heat DMG% boosts alongside its enormous triple-digit Basic Attack DMG increase triggered when using her Ultimate. The thing that sets this weapon apart from the rest is the last part. A huge portion of Laevatain's damage during her Ultimate burst window is Basic Damage, and boosting it by such a big amount, for essentially its entire duration, is just too potent for alternatives to easily compete with.

Solo 91.80%

Team 92.20%

Umbral Torch (P5)

Umbral Torch is Laevatain's battle pass weapon, and at maximum copies, is able to compete somewhat with her signature. It has a similar ideal combination of passive intellect, ATK%, and Heat DMG%, but unlike Forgeborn Scathe, Umbral Torch's weapon passive provides a more modest damage increase while also requiring Combustion or Corrosion to be constantly triggered - something Lae should be doing, but which can experience downtime unless you have multiple sources of application in your team. Calculations have optimal uptime thanks to running Ardelia plus Wulfgard - two consistent appliers of Combustion and Corrosion.

Solo 86.50%

Team 88.90%

Umbral Torch (P0)

At only a single copy, Umbral Torch loses some passive ATK% and a considerable amount of Heat DMG% from its weapon passive effect. Still, even with that considered, it's still a much more attractive choice over a single copy of White Night Nova - Lae's other 6-star option.

Solo 70.30%

Team 75.50%

White Night Nova (P0)

White Night Nova, despite being a 6-star and having an adaptive main stat, isn't able to compete with Laevatain's options above. The reason for this is that this weapon has many of its bonuses in Arts Intensity- a stat which, for Lae, isn't unusable, but isn't nearly as good as some of her other options (most of her damage isn't Arts burst/reaction).

Solo 61.30%

Team 68.10%

Wave Tide (P5)

As a last resort, if you're lacking any of the choices above for the time being, Wave Tide is the most accessible Intellect sword, which also has solid stat bonuses for Laevatain. Use it until you can replace it with one of her higher damage alternatives.

Specialist Weapon Options

Fortmaker (P5)

A specialized option for Laevatain's that are building toward very specific energy breakpoints and which comes a very sizable damage sacrifice compared to all damage options. Should only be used if you know the exact breakpoint you're chasing and if you're confident hitting it will be worth the very large damage loss.

Best Gear

Hot Work

Description

General recommended build for Laevatain, the extra Ultimate Gain Efficiency provided by Redeemer Armor will allow Laevatain to get her Ultimate back within 2 cycles of Enhanced Battle and Combo Skills. This build offers massive Battle Skill DMG%, allowing Laevatain to hit very hard with her Ultimate-Enhanced Battle Skill with proper rotation. Due to the armor offering Ultimate Gain Efficiency, it falls in damage compared to 3pcs Hot Work + LYNX Slab build, but in return it offers flexibility in rotation for Laevatain at lower Potentials.

Hot Work

Description

By forgoing Ultimate Gain Efficiency offered by Redeemer Armor, this build uses LYNX Slab as the off-piece as well as the Hot Work Exo-Rig introduced in 1.1 to create a more damage-optimized build for a well invested Laevatain. LYNX Slab provides Main Attribute % stat that cannot be obtained from anywhere else, and this stat multiplies Laevatain's Intellect attribute giving her a massive Attack boost. However, due to the 0 Ultimate Gain Efficiency provided by the gear, this build may require workaround in rotations to get her Ultimate filled up - such as making use of 3 Combo Skills or more team Battle Skills. Run this build if you have no need of Ultimate Gain Efficiency or can play around it.

Description

Although its damage seems lacklustre at first, a solid build for Laevatain is to go for full Ultimate Gain Efficiency. By forgoing set effects, we instead aim to get enough Ultimate Gain Efficiency on her so that she gets her Ultimate back after using only a single Enhanced Battle Skill + Combo Skill + 2 team Battle Skills. Due to the build being a tradeoff in her Battle Skill DMG for better Ultimate uptime, this build is best paired with her signature weapon, "Forgeborn Scathe", as it gives massive boost to the wielder's Basic Attack DMG. It can also be useful as a quality of life improvement to overworld and daily routing as it only requires Laevatain to do 1 Enhanced Battle Skill cycle to get her Ult back. Note that this build requires artificing to work! For the aforementioned 1 EBS, 1 CS, 2 team BS, thresholds are: P0 Laevatain - 207.7%; P1 Laevatain - 209.4%; P4 Laevatain 178.1%. P1 is higher owing to SP return not contributing any Energy.

Ice Cream Furnace

The first of Laevatain’s potentials that has a real impact on her kit. It lowers her Ultimate energy cost by -15%, reducing its energy requirement from 300 to 255, opening up new potential energy breakpoints and the ability to access her Ultimate much more frequently. After unlocking this potential, it usually makes sense to build some amount of Ultimate Gain on Laevatain to allow her to either enter Ultimate with 2 enhanced Battle Skills in quick succession, or a single enhanced Battle Skill plus team energy and some Combo Skills. Something that, before this potential, wasn’t nearly as viable without sacrificing her set bonus or key gear/weapon pieces.

Synergies

Heat

WulfgardHeat

Wulfgard can serve as either sub-DPS or enabler in Laevatain teams. However, his sub-DPS capability is locked behind his Enhanced Battle Skill that requires 100SP (with return of 10-20SP) and Combustion/Electrification while also not applying any Heat Infliction. Due to that he is more suited to fulfill the role of enabler in most cases.
He fills this role through the Heat Infliction applied by both his Battle Skill and Combo Skill. Having an on-demand applicable Heat Infliction also solves another of Laevatain's out of Ultimate issues, in which she cannot provide Heat Infliction to trigger other teammates' Combo Skills. In addition to that, his Ultimate also forcibly applies Combustion, giving another on-demand way to trigger Laevatain's Combo Skill to generate more Ultimate Energy and Melting Flame.
Wulfgard's P5 is a huge change for an enabler Wulfgard. With P5 unlocked, casting his Ultimate will also reset the cooldown of his Combo Skill, allowing him to apply 3 stacks of Heat Infliction through a rapid succession of Combo Skill > Ult > Combo Skill. At P5 Wulfgard should aim for 232%/242% Ultimate Gain Efficiency (for P0/P1 Laevatain respectively) to get his Ult back in 2 Combo + 2 Skill.
Due to being a Handcannon-wielder, Wulfgard has no access to great supportive weapons. Clannibal has a good buff however it also has the downside of 15s duration with 25s cooldown and needing 80SP with Combustion/Electrification.

Electric

AntalElectric

Being able to provide a stack of Heat Infliction through his Combo Skill; Susceptibility through his Battle Skill's Focus; Amplification through his Ultimate; and as an Arts Unit-wielder, Antal also has access to top-tier supportive weapons. All of these make Antal a solid option to run alongside Laevatain.
Due to his Battle and Combo Skills being single-target oriented, he may feel more clunky in some content compared to other options.
Antal requires 100SP every 60 seconds to apply Focus from his Battle Skill that acts as both a debuff and a condition to trigger his Combo Skill. He can also provide additional sustain with his talent.

Nature

ArdeliaNature

Ardelia's Combo Skill force applies Corrosion to the enemy in an AoE. This allows Laevatain to use her Combo Skill to hit multiple enemies to generate more energy in non-Boss contents while also generating 1 stack of Melting Flame.
Ardelia's Enhanced Battle Skill also provides a very strong Susceptibility debuff on the enemy. Along with her gearing and weapons options, these buffs and debuffs give Laevatain large damage gains with an easy upkeep making her a very good option for Laevatain.
Requires 100 SP every 30 Seconds to keep up with her debuff. However, in times of SP-shortage, you can forgo her Enhanced Battle Skill when it doesn't matter (e.g. Laevatain out of Ult state).

Heat

AkekuriHeat

Contrary to Wulfgard, Akekuri's Battle Skill can apply Heat Infliction in an AoE. When positioned properly her Battle Skill can give more value per 100 SP spent.
Being a Vanguard means Akekuri has access to Thermite Cutter, a powerful buffing weapon and the Frontier set. Alongside that, Akekuri's Potential and Talent can provide 10% ATK and Link buff upon her Ultimate cast to teammates.
Her bad Combo Skill trigger condition is a setback to her SP Recovery capability and Ultimate Energy Recovery. This also means she cannot maintain the uptime of the Frontier set buff well enough in most cases.

Nature

GilbertaNature

Gilberta is a teammate that needs more workarounds than other options such as Ardelia. However, unlike Ardelia, Gilberta requires no SP to access her buffing capability. She also provides a bigger but shorter buff than Ardelia for Laevatain to utilize.
Running Gilberta in the team also has some anti-synergy with other units. Firstly, her Combo Skill will apply a Vulnerable stack on enemy, resulting in a locked Ardelia Combo Skill. Another is her Battle Skill and Ultimate will also apply Nature Infliction, but this is easier to workaround with other units such as Wulfgard's Combo Skill or Laevatain's Ultimate's Enhanced Basic Attack 3rd Sequence. This will help in applying Corrosion or Combustion, triggering Laevatain's Combo Skill to generate energy and 1 Melting Flame stack, which is rarer when you aren't running Ardelia.
Having a Nature Infliction can also benefit Laevatain in some rotations. When having excess Heat Infliction stacks, Gilberta can use her Ultimate or Battle Skill to turn it into Corrosion.
Gilberta is a very strong option and is less SP-hungry but she can feel clunky to use at times. Whether or not to run her comes down to with how comfortable you are with playing Laevatain's team without the addition of forced Corrosion provided by Ardelia or if you prefer to have the SP-less buff provided by Gilberta.

Heat

CamilleHeat

Laevatain is the greatest beneficiary of Camille as of his release, as she:
Has much of her damage be dealt through enhanced Battle Skills, which get a greater boost from Link than Ultimates do (and have rotations be accommodating of double Link set-ups!).
Can absorb Heat Inflictions with her Final Strike and Finishers, making for an easy trigger to Camille's Combo Skill.
The SP recovery and Heat Infliction on Ultimate that Camille provides allows for her to drop Wulfgard from the team if damage is lacking, gaining significant buff value as a result.
Despite her burst value gaining a sizable increase from Camille, she still isn't quite able to match other recent top performers in that aspect, doing best in sustained or multi-target encounters.

Single Target Team

Team Members

Opening Rotation

In single-target battle scenarios, use the rotation as a starting point in order to apply the majority of the team's buffs, build 4 Melting Flame Stacks, cycle through Laevatain's Combo Skill and access her Enhanced Battle Skill quickly. Important to note though, is that if more enemies are present, you'll be able to accumulate Melting Flame more quickly due to Lae's ability to absorb Heat Infliction from all enemies. In these scenarios, feel free to use Lae's Enhanced Battle Skill earlier to accelerate her rotation.

Post Opener Rotation

Laevatain's opener isn't enough to access her Ultimate unless you started the fight with energy already, meaning she'll need another round in order to ensure it's available. In normal circumstances, your queue to start the second half of the rotation is when Ardelia's Combo Skill is back up, and Laevatain's Combo is also close to being available again. Before this point, fill the downtime with Basic Attack Sequences to accumulate Stagger and recover SP. When ready, continue with the below rotation:

Note: The Final Strikes at the end of this rotation are there in order to allow Laevatain's Combo to come back off cooldown so you can immediately trigger it with her Enhanced Battle Skill for extra energy and damage. You need this energy if you're not using Ultimate Gain on Laev, but if you are, you can skip these Final Strikes and the third Combo and use her Enhanced Battle Skill as soon as you have the SP after Ardelia's Battle Skill.

Laevatain Ultimate Usage

How you play within Laevatain's Ultimate state is once again subject to how many enemies are present, what cooldowns you have available, your current SP, whether the enemy/enemies will survive until the Ult ends and how you're playing (are you using animation cancels?). Giving a generalist rotation that takes all this into account at every point of battle is hard, but in general, here is what to look out for:

If possible, ensure Ardelia's Battle Skill Susceptibility is active on your main target before Ulting.
Align Antals Ultimate alongside Laevatains to take advantage of its Amp during your highest burst window. If using Ardelia on Stanza line-up her Ultimate as well for the weapons buff effect.
Ensure you don't overcap on SP during Ultimate, use Wulfgard Battle Skill to dump it and accumulate Heat Infliction, but always save at least 100 for Laevatain's own Battle Skill.
When at 4 Melting Flame Use Laevtain's Ultimate Enhanced Battle Skill to deal damage. Laevatain's combo skill should also be used when available. Both of these abilities freeze the duration of Lae's ultimate when used, so wont waste any precious time.
In AoE scenarios, you'll have much more Melting Flame to work with, so budget your SP around that and use Lae's Enhanced Battle Skill when available.
As Laevtain's Ultimate is drawing to a close, you may consider saving 4 Melting Flame stacks to immediately execute an enhanced battle skill after it ends to recover over 100 energy instantly, although this will require a modified rotation afterwards. If the enemy is likely to die during or shortly after Ult burn all your stacks

Wulfgard Usage

Wulfgard has a few quirks in this team to be aware of, so you get the most out of him and don't waste SP unnecessarily.

When using Wulf's Battle Skill, use it at a time when the enemy isn't suffering from Combustion, otherwise his Battle Skill will change to the Enhanced variants that consume Combustion and doesn't apply Heat Infliction, costing Lae a stack of Melting Flame.
Use Wulfgard's Ultimate as an additional way to access Lae's Combo Skill whenever it's off cooldown. The energy from this ability is crucial, so if Ardelia's Combo and Lae's Enhanced Battle Skill aren't ready, use Wulf's Ultimate to solve the gap, just be careful of the point above.

Extra things to look out for

Laevatain features a number of animation cancels which can be particularly impactful during her Ultimate, allowing more abilities to be fit within its short duration. If you're able to pull these off, it can elevate her damage potential.
Using Ultimate Gain on Laevatain through either the Tide Fall + Hot Work set-up or other sources allows her the energy leeway to execute a 2 Combo rotation instead of 3, shortening the time it takes to get to Ultimate noticeably. However, while this sounds good, it puts heavy pressure on having enough SP to generate the Melting Flame stacks you need while also applying both Antal and Ardelia's buffs.
Both the Opening and Post Opening rotations can be optimized in multi-target scenarios where more Heat Infliction can be expected.
