Valentine's Louis Skills at 5★


Might: 12  Range: 2
Effective against flying foes.
At start of player phase or enemy phase, grants Atk/Def+6, "neutralizes foe's bonuses during combat," and "Special cooldown charge +1 per attack during combat (only highest value applied; does not stack)" to unit and allies within 2 spaces of unit for 1 turn.
Grants Atk/Spd/Def/Res+5 to unit, unit deals +20 damage (excluding area-of-effect Specials), and reduces damage from foe's attacks by 10 during combat (excluding area-of-effect Specials).

Cooldown Count = 4
Boosts damage dealt by 80% of unit’s Def.

If foe initiates combat or if unit's HP ≥ 25% at start of combat, inflicts Atk-5 on foe, deals +X damage (X = 20% of unit's Def; excluding area-of-effect Specials), reduces damage from foe's attacks by X (excluding area-of-effect Specials), unit makes a guaranteed follow-up attack, and neutralizes penalties on unit during combat.

If a foe uses bow, dagger, magic, or staff and initiates combat against an ally with 2 spaces of unit, triggers【Savior】on unit.
If unit triggers Savior, grants Def/Res+4 during combat.
【Savior】
Unit takes ally’s space, enters combat in ally’s place, and receives all after-combat effects.
Doesn't trigger if ally is on terrain that unit can't move to or if multiple units are able to use Savior during the same combat. If Savior triggers, after-combat movement effects don't occur.

Valentine's Louis Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (22) Normal HP ★★★★★
Atk (12) No Attack IV ★★★★☆
Spd (3) Spd Bane ★☆☆☆☆
Def (10) Def Boon ★★★★★
Res (12) Res Bane ★★★★☆

◯ = 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.

+Def / -Spd

The best IVs for Valentine's Louis are +Def and -Spd. As a hero with no exclusive skills, Louis needs to maximize his stat spread to be competitive in the current metagame. Boosting his high base 49 Def to 53 with a superboon allows him to withstand more physical attacks and have him fulfill his role as a physical tank better.

Louis's Spd is a clear dump stat and can be safely taken as a bane as it won't impact any of his matchups.

Valentine's Louis Weaknesses

Low Spd

Valentine's Louis's base 16 Spd is abysmal and he will suffer follow-up attacks against the majority of the other heroes in the game.

He will be reliant on his high HP, Def, and Res stats to withstand damage. Ensure he isn't attacked frequently to keep him healthy!

Lack of Unique Skills

Valentine's Louis suffers from not having any unique skills to call his own, making him unable to stand out amongst other units.

Ranged armored units are quite abundant in the game, and lacking an exclusive skill makes Valentine's Louis replaceable by better units.

Weak to Armor Effective Weapons

X takes 1.5x damage from armor-effective weapons like Randgríðr, and one blow from this type of weapon will deal significant damage. Make sure you know what weapons you are up against before hopping too far into the line of battle!
