Legendary Byleth (M) Skills at 5★


Might: 14  Range: 2
Accelerates Special trigger (cooldown count-1). If unit initiates combat or is within 2 spaces of an ally, grants Atk/Spd/Def/Res+5 during combat, and also, if unit's Spd > foe's Spd during combat, neturalizes effects that guarantee foe's follow-up attacks and effects that prevent unit's follow-up attacks.
Allies within 2 spaces gain: "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."

Cooldown Count = 2
At start of turn, if unit's Special cooldown count is at its maximum value, grants Special cooldown count-1 to unit.
Boosts Special damage by 30% of unit's Atk. If in combat against a dragon foe or beast foe, boosts Special damage by 60% instead of 30%.
When Special triggers, neutralizes "reduces damage by X%" effects from non-Special skills.

Legendary Byleth (M) Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (18) HP Superbane ★★★☆☆
Atk (9) Attack Boon ★★★★☆
Spd (11) Spd Boon ★★★★★
Def (3) Def Bane ★★☆☆☆
Res (8) 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.

+Spd/-Res

The best IVs for Legendary Byleth (M) are +Spd and -Res.

A +Spd IV adds to his best asset, his high Spd stat, and it almost guarantees that the effects of his weapon is active.

His Res is already on the low side, so it would be safe to take it as a bane. You can also settle with -HP.

+Spd for a +10 merge

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

Legendary Byleth (M) Best Weapon Refine

Effect of Legendary Byleth (M)'s Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
SP: 400
Might: 14 Range: 2 HP:
Accelerates Special trigger (cooldown count-1). If unit initiates combat or if there is an ally within 3 rows or 3 columns centered on unit, grants Atk/Spd/Def/Res+5 to unit and deals +7 damage during combat (except when dealing damage with area-of-effect Specials), and also, if unit's Spd > foe's Spd, neutralizes effects that guarantee foe's follow-up attacks and effects that prevent unit's follow-up attacks during combat. For allies within 3 rows or 3 columns centered on unit, grants Atk/Spd+5 to those allies during their combat, and also, if those allies' Spd > foe's Spd, neutralizes effects that guarantee foe's follow-up attacks and effects that prevent those allies' follow-up attacks during their combat.
At start of combat, if unit's HP ≥ 25%, grants Atk/Spd/Def/Res+4 to unit, grants bonus to unit's Atk/Spd/Def/Res = number of allies within 3 rows or 3 columns centered on unit, neutralizes unit's penalties to Atk/Spd, neutralizes effects that grant "Special cooldown charge +X" to foe or inflict "Special cooldown charge -X" on unit, and reduces damage from foe's first attack by 30% during combat ("first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes). Neutralizes penalties to Atk/Spd on allies within 3 rows or 3 columns centered on unit during their combat.
Arena Medal:500 Divine Dew:200

We recommend the Special Effect Refine for Professorial Text

Refined Professorial Text grants Atk/Spd+4, Def/Res+9 to Byleth in-combat, bonus stats to his allies within 3 rows and 3 columns, bonus true damage, a Tempo effect, and 30% damage reduction on foe's first attack.

Additionally, it grants both Byleth and his allies within 3 rows and 3 columns Atk/Spd+5, Spd-based Null Follow-Up, and Atk/Spd debuff neutralization.

This refine aids both Byleth and his allies, improving both his combat and his support.

As a Legendary Hero, you will gain a Water Blessing when summoning L!Byleth (M). Additionally, being a Water type Legendary Hero means that during Water Seasons, other allies with a Water Blessing will receive HP+3 when they appear in battle with L!Byleth (M), and Legendary Byleth's total stats will be treated as 190. This will lead to a higher Arena Score.

Legendary Byleth (M) Strengths

Professorial Text provides both offense and support

Professorial Text accelerates Byleth's special cooldown and provides buffs to all of Byleth's stats.

Upon winning a Spd check, Professorial Text:

  1. Neutralizes effects that guarantee foe's follow-up attacks like Vengeful Fighter 3
  2. Neutralizes effects that prevent Byleth from scoring follow-up attacks like Wary Fighter 3

Professorial Text also provides the above effects to nearby allies, assuming those allies also win a Spd check of their own.

When refined, Professorial Text grants Atk/Spd+4, Def/Res+9 to Byleth in-combat, bonus stats to his allies within 3 rows and 3 columns, bonus true damage, a Tempo effect, and 30% damage reduction on foe's first attack.

Additionally, it grants both Byleth and his allies within 3 rows and 3 columns Atk/Spd+5, Spd-based Null Follow-Up, and Atk/Spd debuff neutralization.

This refine aids both Byleth and his allies, improving both his combat and his support.

Sublime Heaven II pre-charges every turn

Sublime Heaven II is an upgraded version of Byleth's original exclusive Special, Sublime Heaven. This improved Special has built-in Time's Pulse 3, boosts damage by 30% of his Atk (60% against dragons and beasts), and neutralizes non-Special damage reduction effects whenever it triggers.

This Special skill only has 2 cooldown, lowered to 1 when equipping Professorial Text. With the Time's Pulse 3 effect, Byleth will have this Special ready every turn!

Legendary Byleth (M) Weaknesses

Dependence on Spd Checks

Byleth needs to win a Spd check to activate the most important part of his weapon - the Null Follow-Up effect. With common meta units having high speed, Byleth needs to be invested well enough to ensure he wins the Spd check every time.

Low Def and Res

Legendary Byleth's Def and Res are on the low side and this makes it easy for melee units to take him out.

Be mindful of his positioning in relation to these types of units as even if his Spd is higher, units with very high or have brave weapons can defeat him.

Value of Skills ★★★★☆

The following skills have good inheritance value:

  • Atk/Def Ideal 4
  • Lull Atk/Res 3
  • Time's Pulse 3

We do not recommend fodderring off Legendary Byleth (M)! But the skills listed above have inheritance value. Take note that Lull Atk/Res 3 is becoming more and more common so you may want to look at the other two skills instead. As of July 2021, Atk/Def Ideal 4 is currently rarer than Time's Pulse 3.
