Laevatain is a Heat AoE monster whose Magma Fragment Battle Skill and Ultimate-centered dumps clear packs that single-target carries struggle with. She wants energy routing — Tide Fall and Hot Work style setups — and feels weaker if you cannot feed Ultimates, but inside a dedicated Heat team she remains a premier pack-clear option. Pull when you need a Heat carry and will build the energy package around her; pass if you refuse Ultimate-gated DPS or already clear Heat content another way.
Laevatain is a 6★ Heat Main DPS (Sword). Laevatain is a Heat Damage monster whose Battle Skill has the ability to summon a Magma Fragment, and trigger temporary Combustion to all enemies in a large area.
Weapon
Forgeborn Scathe
Signature option. It grants the wielder Heat damage and a large Basic Attack Damage bonus after triggering their Ultimate, for 20 seconds.
Gear Set
Hot Work
The Hot Work 3-piece set bonus grants a large Heat damage bonus whenever the wearer applies Combustion - a perfect fit for Laevatain, who can trigger this on demand with her Battle Skill. You will want to combine this with an Offpiece that grants Ultimate Gain Efficiency, to have more frequent access to her powerful Ult.

Use these notes as the operator priority order inside the comps above.

Intellect Boost [L] · Attack Boost [L]
Heat DMG Dealt +16/28.8/44.8%. When the wielder casts an ultimate, the wielder gains Basic Attack DMG Dealt +75/135/210% for 20.00s. Effects of the same name cannot stack.
Why it works —Signature option. It grants the wielder Heat damage and a large Basic Attack Damage bonus after triggering their Ultimate, for 20 seconds.

Intellect Boost [L] · Heat DMG Boost [L]
ATK +7/12.6/19.6%. Whenever Combustion or Corrosion is applied to an enemy, the wielder gains Heat and Nature DMG Dealt +8/14.4/22.4% for 20.00s. Max stacks for effects of the same name: 2.00. Duration of each stack is counted separately. Effect only triggers once every 0.1s.
Why it works —As a more free-to-play option, Umbral Torch grants Attack as well as a Heat and damage boost for each enemy afflicted with Combustion, stacking up to 3 times. This effect works pretty well with Laevatain's kit, since she can forcibly trigger a temporary Combustion with her Battle Skill.

Intellect Boost [M] · Ultimate Gain Efficiency Boost [M]
ATK +5/9/14%. Arts Intensity +25/45/70.
Why it works —For a 5 Star option, Fortmaker slots in well since its main stat lines up with Laevatain's stat specialty and its secondary can feed into her Ultimate Gain and its got an intrinsic attack boost as well.

Intellect Boost [S] · ATK Boost [S]
When the wielder casts a combo skill, the wielder gains ATK +12/21.6/33.6% for 20.00s. Effects of the same name cannot stack.
Why it works —For a 4 Star Option, Wave Tide will work well. The fact is though that with the availability of 5 Star options, this weapon should only ever really be used in a leveling situation and replaced with something better as soon as possible.

Hot Work is Laevatain's BiS. Applying Combustion with her Battle Skill immediately triggers the set's Heat DMG bonus — on-demand, every rotation. Pair with an Ultimate Gain Efficiency off-piece so her Ult stays frequent.

Heat Combustion carry: Camille fuels SP, Arcane groups or amps, Ardelia sustains — Laevatain detonates Combustion on Battle Skill inside the window.

Camille fuels SP so Laevatain can Battle Skill Combustion and Ult on a short cycle.
Arcane covers grouping/Susceptibility or secondary Arts damage while Laevatain owns the Combustion Heat dump.
Ardelia keeps Laevatain alive through Combustion commits and adds Susceptibility amp on the dump.
BASIC ATTACK: An attack with up to 5 sequences that deals Heat DMG. As the controlled operator, Final Strike also deals 18 Stagger. DIVE ATTACK: Basic attack performed in mid-air becomes a dive attack that deals Heat DMG to nearby enemies. FINISHER: Basic attack performed near a Staggered enemy becomes a finisher that deals massive Heat DMG and recovers some SP.
SKILL DESCRIPTION: Summons a Magma Fragment to continuously attack enemies and deal Heat DMG. Hitting the enemy grants 1 stack of Melting Flame. If Laevatain already has 4 stack(s) of Melting Flame when casting the skill, then consume all the stacks and perform 1 additional attack that deals Heat DMG and forcibly trigger temporary Combustion to all enemies in a large area. When the additional attack hits the enemy, restore additional Ultimate Energy. Battle skill effects are enhanced while Laevatain's ultimate is active.

SKILL DESCRIPTION: Laevatain summons her Sviga Lævi and becomes the controlled operator. For a certain duration, her basic attacks (BATK) are enhanced and the Sviga Lævi strikes together with Laevatain, with each attack dealing Heat DMG. BATK sequence 3 also applies Heat Infliction. Casting the battle skill, Smouldering Fire, or the combo skill, Seethe, does not shorten the duration of the ultimate, Twilight.
Operator Intellect +10. / Operator Intellect +15. / Operator Intellect +15. / Operator Intellect +20.
After the controlled operator's Final Strike or Finisher hits the enemy, Laevatain absorbs Heat Infliction from nearby enemies.

Laevatain also absorbs Heat Infliction from enemies defeated nearby.
