Byleth (F) Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (18) HP Superbane ★★☆☆☆
Atk (26) No Attack IV ★★★★★
Spd (10) Spd Boon ★★★★☆
Def (7) No Def IV ★★★☆☆
Res (4) No Res IV ★☆☆☆☆

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

+Atk/-Res

Byleth's best IVs are +Atk and -Res. Byleth has such high Spd that follow-up attacks are extremely easy to come by, so maximizing the damage output is the way to good. If you want to ensure she gets a follow-up attack when going into battle, Spd is a superboon, making it a a good asset as well.

F!Byleth is a close ranged 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.

Byleth (F)'s Strengths

Exclusive weapon has Null Follow-Up built into it

F!Byleth's exclusive weapon skill, Creator Sword, has the effect of Null Follow-Up. This will allow her to reduce the damage taken from foes with skills like Bold Fighter and Quick Riposte, and will also allow her to make a follow-up attack even against foes with the skill Wary Fighter.

Can neutralize skills that change special cooldown

Creator Sword will also prevent any enemy skill from slowing down or speeding up a special's cooldown or speeding up. This means that she can nullify Flashing Blade or Heavy Blade and use her special without being affected by Special Fighter or Guard.

Low cooldown special that is effective on dragons and beasts

Her special skill Ruptured Sky will boost damage by 40% of a foe's Atk if they are a dragon or beast. When her HP drops to 75%, Byleth will be able to use the effects of Wrath and Ruptured Sky together to get a guaranteed special, which lets her deal heavy damage to characters like Tibarn or Duma.

Byleth (F)'s Weaknesses

Weak to magic attacks

With her low Res stat, F!Byleth will take a lot of damage from mages and dragons. Keep her out of reach from powerful blue mages like Reinhardt and Ophelia.

Quotes: Castle

See Castle Quotes
Everyone here has a fighting spirit. In that respect, this place feels much like the Officers Academy.
When I was a mercenary, I rarely got too close to anyone. That all changed when I became a professor.
I can patrol the area if need be. I have experience from my mercenary days, and from watching over my students.
As a professor, I spend most of my time teaching others. But I believe I could learn something from you.
I sometimes feel I am grasping for a purpose in life. Perhaps someday I will know what it is.

Lv 40 Dialogue

See Lv 40 Dialogue
How long has it been since I was summoned to this world to fight alongside you?
The flow of time brought us together, and now we are bound inextricably. I am your ally, and you are mine.
I have not forgotten the needs of my students. But I have no regrets about my decision to join your cause.
The Sword of the Creator empowers me to sever my doubts—to carve a path through tangles of uncertainty.
With this sword in hand, I will defeat our foes and lead us to victory.
