Taking one combat skill from level 1 to 12 costs 172,200 T-Creds and 21× Blighted Jadeleaf among other materials. The Materials tab lists every item per level.

Heart of Melting Flame: Battle skill Smouldering Fire improved: Additional attack multiplier is increased to 1.2 times the original, and scoring a hit returns 20 SP.

BISForgeborn Scathe

100.00% solo · 100.00% in team at P0

Laevatain's signature is her best weapon, with passive Intellect, ATK%, and Heat DMG% plus a huge triple-digit Basic Attack DMG boost that kicks in with her Ultimate, when most of her burst damage is Basic Attack damage anyway.

#2Umbral Torch

91.80% solo · 92.20% in team at P5

At maximum copies, Umbral Torch nearly matches her signature with a similar Intellect, ATK%, and Heat DMG% combo, though its passive gives a smaller boost and needs Combustion or Corrosion kept up, assumed here via Ardelia and Wulfgard.

#3White Night Nova

70.30% solo · 75.50% in team at P0

White Night Nova is a 6-star with an adaptive main stat, but its bonuses lean on Arts Intensity, a stat Laevatain can use but doesn't need much since most of her damage isn't an Arts burst or reaction.

Wave Tide is a last resort, the most accessible Intellect sword with solid stat bonuses, worth using only until you replace it.

CoreHot Work

The general build pairs Hot Work's massive Battle Skill DMG% with Redeemer Armor's Ultimate Gain Efficiency to refill her Ultimate within 2 cycles, trading some damage against the LYNX Slab build for flexibility at lower Potentials.

3PC3-piece set effect: Wearer's Arts Intensity +30. After the wearer applies Combustion, the wearer gains Heat DMG +50% for 10s. After the wearer applies Corrosion, the wearer gains Nature DMG +50% for 10s. The aforementioned effects cannot stack.

No Set: Full Ultimate Gain Efficiency with no set looks weak but, paired with her signature, refills her Ultimate off 1 Enhanced Battle Skill, 1 Combo, and 2 team Battle Skills, needing about 207.7% at P0, 209.4% at P1, or 178.1% at P4.

Laevatain FAQ

What attribute is Laevatain?: Laevatain is a 6-star Heat operator of the Striker class, from Rhodes Island, wielding a Sword, released in version 1.0.
What stat does Laevatain scale on?: Laevatain's skills multiply ATK. That is read from the scaling rows on the Battle Skill and Ultimate, not from the skill description, so it reflects what the game actually multiplies rather than what the text mentions.
What is the best weapon for Laevatain?: Forgeborn Scathe is the closest fit on the data: it is a 6-star Sword with 510 base ATK at level 90, and its skills act on ATK. Wave Tide is the best 4-star alternative.
Which gear set should Laevatain use?: Hot Work. Its 3-piece effect is: 3-piece set effect: Wearer's Arts Intensity +30. After the wearer applies Combustion, the wearer gains Heat DMG +50% for 10s. After the wearer applies Corrosion, the wearer gains Nature DMG +50% for 10s. The aforementioned effects cannot stack. The 3-piece effect is the only set bonus a gear set has, and it needs three matching pieces; an operator equips four in all (Armor, Gloves and two Kits), so the fourth is free for an off-set piece.
How much does it cost to max Laevatain's skills?: Taking one combat skill from level 1 to 12 costs 172,200 T-Creds and 21× Blighted Jadeleaf among other materials. The Materials tab lists every item per level.
What does Laevatain P1 do?: Heart of Melting Flame: Battle skill Smouldering Fire improved: Additional attack multiplier is increased to 1.2 times the original, and scoring a hit returns 20 SP.
