Captain's Sword Might: 16　 Range: 1 Accelerates Special trigger (cooldown count-1). Foes with Range = 1 cannot move through spaces adjacent to unit, and foes with Range = 2 cannot move through spaces within 2 spaces of unit (does not affect foes with Pass skills). At start of combat, if unit's HP ≥ 25%, grants Atk/Spd/Def/Res+5 to unit and neutralizes foe's bonuses (from skills like Fortify, Rally, etc.) during combat, restores 7 HP to unit after combat, and also, if foe initiates combat and unit's Spd > foe's Spd, unit can counterattack before foe's first attack.

Divine Pulse Cooldown Count = 2 Boost Dmg by 25% of unit's Spd. Reduces damage from foe's next attack by 75%, and unit's next attack deals damage = 20% of unit's Spd. (Resets at the end of combat.)

Distant A/S Solo Unit can counterattack regardless of foe's range. If unit is not adjacent to an ally, grants Atk/Spd+5 to unit during combat.

Close Call 4 Inflicts Spd/Def-4 on foe during combat. If a skill compares unit's Spd to a foe's or ally's Spd, treat unit's Spd as if granted +7. If unit's Spd > foe's Spd, reduces damage from attacks during combat and from area-of-effect Specials by percentage = difference between stats x 5; max 50%. If unit initiates combat, unit moves 1 space away after combat.

Time's Pulse 4 At start of turn, if Special cooldown count is at its maximum value, grants Special cooldown count-1. After combat, if Special cooldown count is at its maximum value, grants Special cooldown count-1.

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (18)		★★★☆☆
Atk (11)		★★★★☆
Spd (8)		★★★★★
Def (8)		★★★☆☆
Res (10)		★★☆☆☆

◯ = 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 Fallen Byleth (F) are +Spd and -Res. Spd is a superboon and raises Byleth's base Spd from 47 to 51. Her base Spd is the highest in the game as of the time of her release, and a superboon ensures that she is the fastest unit on the field.

Her Res is below average and can be safely taken as a bane as it will not have much impact, especially with two layers of damage reduction in her kit.

+Spd for a +10 merge

We recommend a +Spd IV when merging Fallen Byleth (F) up to +10. Her kit revolves around her impressive Spd stat and it should be boosted as much as possible.

Fallen Byleth (F) Roles, Strengths, and Weaknesses

Fallen Byleth (F) Roles

Byleth - Vengeance Vessel 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

Fallen Byleth (F) 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.

Fallen Byleth (F) Strengths

Captain's Sword grants multiple effects!

Fallen Byleth (F) wields the Captain's Sword this time around. This exclusive weapon grants an accelerated Special trigger, Atk/Spd/Def/Res+5 during combat, has a Bulwark effect that prevents foes from moving through nearby spaces and heals Byleth for 7 HP after combat, and has a Vantage effect upon winning a Spd check.

This loaded weapon dumps a lot of different effects onto Fallen Byleth (F), making her difficult to counter outright. The Bulwark effect prevents her foes from simply bypassing her and attacking the back line, and the Vantage effect ensures that Byleth deals significant damage, or outright knocks out, any enemies that approach.

Divine Pulse is a quick Special that boosts damage and grants damage reduction

Fallen Byleth (F) also comes with an exclusive Special in Divine Pulse similar to Brave Byleth (F). It is a 2 charge Special (reduced to 1 charge due to Captain's Sword).

Divine Pulse boosts Fallen Byleth (F)'s damage by 25% of her Spd, reduces damage from her foe's next attack by 75%, and boosts her next attack by 20% of her Spd.

Since Divine Pulse is a Special skill, effects that pierce non-Special damage reduction like Deadeye do not affect the damage reduction provided by Divine Pulse.

Base kit synergy is very high

The synergy between Divine Pulse, Captain's Sword, and Time's Pulse 4 make Fallen Byleth (F) a difficult unit to bring down.

Due to Time's Pulse 4, Divine Pulse is always available before combat, granting one layer of damage reduction as well as bonus damage. Close Call 4 provides another layer of damage reduction, and Distant A/S Solo grants bonus stats and allows counterattacking at any range.

The Bulwark effect forces foes to deal with Byleth first, and the Vantage effect forces foes to have units that survive a Divine Pulse boosted attack, otherwise they get checkmated. Even if the enemy hero survives the first attack, they have to get through two layers of damage reduction first, making Fallen Byleth (F)'s survival incredibly likely.

Fallen Byleth (F) Weaknesses

Reliance on Outspeeding Foes

Fallen Byleth (F)'s kit relies on her outspeeding her foes in order to get maximum value. The Vantage effect and Close Call 4's damage reduction do not function if Byleth is outsped.

On a similar note, the damage from Divine Pulse is reliant on Byleth's Spd. Byleth's base kit does not have a way to neutralize or reverse penalties inflicted unto herself, making her susceptible to all sorts of penalties.

Ensure that Byleth's Spd remains high in order to make her as strong as possible.

Fallen Byleth (F) as a Source Hero

Value of Skills	★★★★★

Fallen Byleth (F) has Distant A/S Solo, Close Call 4, and Time's Pulse 4 as valuable inheritance options.

All of these skills are very rare and are worth inheriting onto your favorite units. Distant A/S Solo is only found on Fallen Byleth (F) as of the time of her release.

However, Fallen Byleth (F) is a very powerful unit. Consider keeping her in your barracks instead.
