When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Spd/-HP

The best IVs for Karla are +Spd and -HP. Karla's weapon, the Vassal's Blade, relies on her having a high Spd in order to dish-out damage. It also allows her to dish-out many follow-up attacks that greatly increase her damage output. Her HP is of less importance for her making it safe to take as her bane.

Karla Best Builds

Refined - Flashing Vassal Karla

： Vassal's Blade ： Reposition ： Luna ： -

： Flashing Blade 4 ： Spurn 3 ： Joint Hone Spd ： Blade Session 3 ： -

How to Use, Explanation

To Karla, Spd is the name of the game. By stacking lots of Spd, she increases her bulk through Spurn 3 and damage through Vassal's Blade and follow-up attacks. This build does exactly just that. She also deals lots of pure, flat damage with this build thanks to Flashing Blade 4 and Vassal's Blade.

Firesweep Karla

： Firesweep Sword+ ： Reposition ： Galeforce ： -

： Life and Death 4 ： Hit and Run ： Fatal Smoke 3 ： Heavy Blade 3 ： -

How to Use, Explanation

Karla's refined Vassal's Blade is strictly superior than a Firesweep setup, but this is a nice set if you want to run this niche. If you cannot afford Fatal Smoke 3, you can go for Panic Smoke 3, or any Smoke skill. You can also go for a Lull skill in the B slot.

Aether Raids / General Use / Arena Karla

HOT
： Vassal's Blade ： Reposition ： Ruptured Sky ： -	： Swift Sparrow 3 ： Windsweep 3 ： Joint Drive Spd ： Atk/Spd Solo 3 ： -

How to Use, Explanation

This is a general build using Karla's refined weapon that can also be used in Aether Raids. While you can normally run Moonbow on her, Ruptured Sky will help her take down pesky Fallen Edelgards, while ensuring that she doesn't get counterattacked in return due to Windsweep 3. You can run Swift Sparrow 2 as a budget option or Atk/Spd Solo 3 or 4 on her A slot. Her C skill can be either Joint Drive Attack or Joint Drive Speed if you have the fodder, though you can also run Spd Smoke 3 as a budget option.
This build will also make her score high in the Arena, but you will need to replace Reposition with a higher-scoring Assist skill. Any dual Rally skill like Rally Atk/Spd+ will do in this case.

Damage Reduction Build Karla

HOT
： Vassal's Blade ： Reposition ： Ruptured Sky ： -	： Distant Counter ： Spurn 3 ： Joint Drive Spd ： Atk/Spd Solo 3 ： -

How to Use, Explanation

This build takes advantage of the various buffs given by the refined Vassal's Blade to stack up Spurn's damage reduction and retaliate with Ruptured Sky. The Null Follow-Up effect on Karla's weapon ensures that her ability to double is based on a speed check, which she should almost always win thanks to her naturally high speed stat and the various passive buffs given by her weapon, Joint Drive Spd, and Atk/Spd Solo 3.

Karla Best Weapon Refine

Effect of Karla's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
Vassal's Blade	SP: 400
Might: 16　Range: 1　HP: +3 Accelerates Special trigger (cooldown count-1). If unit initiates combat or is within 2 spaces of an ally, grants Spd+5 to unit during combat and deals damage = 15% of unit's Spd. At the start of combat, if foe's HP ≥ 75%, grants Atk/Spd+5 during combat and neutralizes effects that guarantee foe's follow-up attacks and effects that prevent unit's follow-up attacks during combat. ：500　：200

We recommend the Special Effect Refine for Vassal's Blade

Vassal's Balde's refine gives Karla Atk/Spd+5 if her foe's HP is ≥ 75% and a Null Follow-Up 3 effect.

We recommend getting this refine as not only will Karla be giving herself +10 Spd at the start of combat, but will also nullify an enemy unit's guaranteed follow-up attack and effects that prevent her from performing a follow-up attack.

This allows Karla to double without fear and potentially one-shot enemy units.

Karla Roles, Strengths, and Weaknesses

Karla Roles

Karla - Sword Vassal Roles
Close-Physical	Ranged-Physical	Close-Magic	Ranged-Magic
Physical Wall	Magic Wall	Effective Weapon	Movement Assist
Exclusive Skill	All-Range Counter	Recovery	Refresher
Legendary	Mythic	Duo / Harmonized	Resplendent

Karla is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent to her Atk minus the foe's Def stat.

Karla Strengths

Acquire Additional Damage by Stacking Spd

Vassal's Blade deals bonus damage if Karla's Spd is more than her foes. The bonus damage is calculated by 70% of the difference in Spd.

With her weapon's refine, Karla is able to buff herself further with more Atk and Spd, giving herself +5 in those stats if her HP is ≥ 75%. This means that she will be able to deal more free damage that an enemy unit cannot block, regardless of their color or Def.

This effect is compatible with the Phantom Spd Sacred Seal that treats Elise as if she has +10 Spd whenever there is a Spd check.

Vassal's Blade's refine gives Null Follow-Up 3

In addition to giving herself Atk/Spd+5, the refine for Vassal's Blade will give Karla the Null Follow-Up 3 effect.

This makes her an effective offensive unit as she prevents guaranteed follow-up attacks and prevents effects that prevent her from making follow-up attacks. With this effect she can take down the most difficult units like Fallen Edelgard.

Wrath Speeds-up Special Cooldown

Wrath 3 speeds-up Karla's special cooldown and grants +10 pure damage to her whenever her special is activated. If you stick with Karla's native special, Draconic Aua, you will be able to shred through most enemies that does not have an abnormally high Def stat. This synergizes well with Karla's play style and kit as it requires her to stack a lot of Spd. Having a high Spd means you score follow-up attacks more often and both those attacks help in activating a Wrath-charged Draconic Aura.

Team gets a Spd boost on Even numbered turns

Karla's default C skill Even Spd Wave will grant Karla and adjacent allies Spd +6 on even numbered turns. Since this C skill actually gives the bonus to Karla and not just her allies, her weapon, Vassal's Blade, can utilize its effects and add to her damage output in said turns.

Karla Weaknesses

Low Defenses

Karla's Spd is high, but both her Res and Def are very low. Look out for characters like Reinhardt, Olwen, or those who possess any kind of Brave weapons their as extra attacks ignore Spd's ability to block a second hit.
