Stat Superboon/Superbane IV Recommendation
HP (18) Normal HP ★★☆☆☆
Atk (23) No Attack IV ★★★★☆
Spd (10) Spd Boon ★★★★★
Def (6) No Def IV ★★☆☆☆
Res (7) No Res IV ★★☆☆☆

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws

+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.

Aether Raids / General Use / Arena KarlaHOT

See Explanation and Source Heroes

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.

Karla Best Weapon Refine

Effect of Karla's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
SP: 400
Might: 16 Range: 1 HP:
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.
Arena Medal:500 Divine Dew: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 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.

Karel... Even if things can never again be how they were... I must keep going.
Only one can wield the sword of our clan. Aside from my brother, all have fallen... As will I, someday.
And yet...here I am.
Your diligence is worthy of respect. Take care not to overtax yourself, however.
I have seen much on my journey, but the sights here are rare indeed. Do you have the time to be my guide?
Saw me training, did you? You might think I have no need to, but the habit is ingrained deep within me.

Lv 40 Dialogue

My clan lives by the sword. Our lives are spent improving our skills and slaying our foes.
Even our kin fall to our blades...
After leaving the plains, I came to realize that this is not the only form strength takes.
A sword is just a sword.
One man showed me how to truly become stronger...
My brother has also realized that the way of the sword is not merely killing others.
And after spending some time observing you, I have seen a new kind of strength.
How can I describe it? It is a strength honed by choosing not to fight.
I find it fascinating.
Until I can fully understand it... I will stay by your side.
