Ruptured Sky Cooldown Count = 2 Boosts damage by 20% of foe's Atk. If in combat against a dragon foe or beast foe, boosts damage by 40% instead of 20%.

Atk/Spd Ideal 4 At start of combat, if unit's HP = 100% or if 【Bonus】 is active on unit, grants Atk/Spd+7 to unit during combat. At start of combat, if unit's HP = 100% and 【Bonus】 is active on unit, grants an additional Atk/Spd+2 to unit during combat.

Lull Spd/Res 3 Inflicts Spd/Res -3 on foe and neutralizes foe's bonuses to Spd/Res (from skills like Fortify, Rally, etc.) during combat.

Goddess Bearer At start of turn, if unit is within 2 spaces of an ally, grants Atk/Spd+7, 【Null Follow-Up】, and the following status to unit for 1 turn: "Unit can move to a space adjacent to any ally within 2 spaces." 【Null Follow-Up】 If unit's Spd > foe's Spd during combat, neutralizes effects that guarantee foe's follow-up attacks and effects that prevent unit's follow-up attacks for 1 turn.

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/-Def

The best IVs for Legendary Byleth (F) are +Spd and -Def. Her entire kit is reliant on boosting her Spd as much as possble, thus the decision to take it as a boon.

Byleth's Def is very low, and she shouldn't be taking attacks from physical units in the first place so this is the best bane she can take.

+Spd for a +10 Merge

We recommend a +Spd IV when merging Legendary Byleth (F) to 10. This is for the same reasons as above.

Physical Wall	Magic Wall	Effective Weapon	Movement Assist
Exclusive Skill	All-Range Counter	Recovery	Refresher
Legendary	Mythic	Duo / Harmonized	Resplendent

Legendary Byleth (F) is a ranged magic attacker (range = 2). Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent to her Atk minus the foe's Res stat.

Legendary Effect boosts Arena score

Eff.	Atk+2	Spd+3	Def+4	Res+4	Pair Up

Pair Up and Eff.	Atk+2	Spd+3	Def+4	Res+4

As a legendary hero, the Summoner receives a Wind Blessing by default when Legendary Byleth (F) is summoned. Being a wind-type Legendary Hero means that during Wind Season, Wind-blessed heroes will gain HP+3, and Legendary Byleth (F)'s effect will make her base stats be treated as 185. This effect makes it easy to raise your arena score when playing her on your team.

Legendary Byleth (F) Strengths

Professorial Guide is a Powerful Tome

Byleth repeatedly attacks the Red Fafnir!

Professorial Guide is a powerful tome, assuming Legendary Byleth (F) meets the conditions to activate it in combat.

It grants an accelerated Special cooldown no matter what, and provides additional effects if Byleth initiates combat or if she is within 2 spaces of an ally.

Below is a summary of its effects if Byleth initiates combat or if she is within 2 spaces of an ally:

1	Grants Atk/Spd/Def/Res+5 during combat
2	Neutralizes Guard effects that the foe applies to Byleth

In addition to this, Professorial Guide also grants the following effects to allies within 2 spaces of Byleth:

1	Neutralizes effects that grant 'Special cooldown charge +X' to foe during combat
2	Neutralizes effects that inflict 'Special cooldown charge -X' on unit during combat

This powerful tome not only strengthens Byleth during combat, it also empowers her allies! It is perfect for a professor like Byleth.

Goddess Bearer Boosts Atk/Spd and grants Null Follow-Up and Warp statuses

Legendary Byleth (F) comes with a unique Passive C skill in Goddess Bearer.

This skill activates at the start of each turn and grants Byleth Atk/Spd+7, the 【Null Follow-Up】status, and the ability to warp to an adjacent space to any ally within 2 spaces.

The Atk/Spd bonus received here is a visible bonus, which works perfectly with her native Atk/Spd Ideal 4 skill!

Legendary Byleth (F) Weaknesses

Dependence on Spd Checks and other Conditions

Legendary Byleth (F)'s unique skills require her to either initiate combat or be within 2 spaces of an ally. These may restrict your movement and action plans for future turns if you want to keep these skills active.

Additionally, Byleth needs to win a Spd check to activate the Null Follow-Up effect of Goddess Bearer. With common meta units having high speed, Byleth needs to be invested well enough to ensure she wins the Spd check every time.
