Spring Karla Skills at 5★


Might: 16  Range: 1
Accelerates Special trigger (cooldown count-1). At start of odd-numbered turns, grants Special cooldown count-2. If unit initiates combat or is within 2 spaces of an ally, grants Atk/Spd+6 to unit during combat and deals damage = X% of unit's Spd when Special triggers (X = unit's max Special cooldown count value x 10, + 20). If unit initiates combat or is within 2 spaces of an ally, and if unit's Special triggers (excluding area-of-effect Specials), disables non-Special effects that "reduce damage by X%" and prevents foe's Specials that are triggered by unit's attack.

Cooldown Count = 3
Boosts Atk by 30%.

If unit or foe initiates combat after moving to a different space, grants bonus to unit's Atk/Spd during combat = X + 6 (X = number of spaces moved by whoever initated combat; max 4.) If X ≥ 2, neutralizes unit's penalties to Atk/Spd during combat.

Enables 【Canto (Rem. +1)】.
If unit inifiates combat, neutralizes effects that prevent unit's follow-up attacks.
After an attack, Assist skill, or structure destruction, unit can move spaces = any movement not already used that turn + 1. (If unit used a movement skill that warped them, its remaining movement is 0.)
(Unit moves according to movement type. Once per turn, cannot attack or assist. Only highest value applied. Does not stack. After moving, if a skill that grants another action would be triggered (like with Galeforce), Canto will trigger again. Unit's base movement has no effect on movement granted. Cannot warp (using skills like Wings of Mercy) a distance greater than unit's remaining movement +1.)

After combat, inflicts Spd-7 on target and foes within 2 spaces of target through their next actions, and grants Spd+6 and 【Dodge】 to unit for 1 turn.

Spring Karla Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (18) HP Superbane ★★★☆☆
Atk (15) Attack Boon ★★★★★
Spd (8) Spd Boon ★★★★★
Def (5) Def Boon ★★☆☆☆
Res (5) No Res IV ★★☆☆☆

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

See the IV Checker for All Units Trait Fruits—How to Change IVs

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 / -Res

The best IVs for Spring Karla are +Spd and -Res. Her Spd is the highest in the game as of the time of her release at base 47, boosted to 51 with a superboon. Spd is her best stat and is very useful for creating follow-up attacks through a Spd check.

Spring Karla's Def and Res are both suboptimal. We opted for a Res bane as she will be initiating combat and is more likely to receive counterattacks from physical foes.

+Spd for a +10 merge

We recommend a +Spd IV when merging Spring Bernadetta to +10 for similar reasons above.

Spring Karla Best Builds

Tankbuster Spring Karla

Emblem Icon: -
Attuned Skill Icon: -

How to Use, Explanation

Spring Karla's base kit already functions spectacularly as a tankbuster unit. A 3 cooldown Special like her Draconic Aura charges up immediately on the first turn, while a 5 cooldown Special like Aether requires waiting until turn 3 to pre-charge, but hits significantly harder.

Spring 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.

Spring Karla Strengths

Sisterly War Axe is an incredible offensive weapon

Spring Karla Attack Fire Emblem Heroes FEH

Spring Karla's Sisterly War Axe accelerates her Special trigger and grants Special cooldown count -2 at the start of each odd-numbered turn. This effect allows Spring Karla to quickly charge up her Specials and reliably trigger them in combat very often, making her a very dangerous opponent to meet on the field.

In combat, Sisterly War Axe grants Atk/Spd+6 and true damage equal to a percentage of her Spd based on her Special's maximum cooldown count whenever her Special triggers. Additionally, if Spring Karla initiates or is near an ally and she triggers her Special, she disables damage reduction effects and prevents defensive Specials such as Pavise and Godlike Reflexes from triggering.

This combat effect makes Spring Karla a premiere tankbuster unit capable of punching through enemies and ignoring all damage reduction effects, including said Specials.

Harmonized Skill grants Special cooldown charges, bonus Atk and Spd

Spring Karla's Harmonized skill grants Special cooldown count -2, Atk+6, and 【Resonance: Blades】 to herself and all allies from Blazing Blade and Heroes for one turn.

This effect can set up teams to wipe multiple enemies if the team is properly built with heroes from these titles.

Spring Karla Weaknesses

Weak to Cavalry Effective Weapons

Spring Karla takes 1.5x damage from cavalry-effective weapons like Thani or Binding Reginleif, and one blow from this type of weapon is sure to take her down. Make sure you know what weapons you are up against before hopping too far into the line of battle!
