Emblem Byleth (M) Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (18) HP Superbane ★★★☆☆
Atk (11) No Attack IV ★★★★☆
Spd (10) Spd Boon ★★★★★
Def (11) Def Boon ★★★☆☆
Res (4) 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 Emblem Byleth (M) are +Spd and -Res. Byleth's base 49 Spd, raised to base 53 with a superboon, is among the fastest in the entire game. He can utilize his high Spd to prevent fast metagame foes from generating follow-up attacks against him while also creating his own follow-up attacks against slower foes.

Byleth's base 17 Res is very poor and can be exploited by high damage magical nukers to defeat him in one round of combat. Keep Byleth away from these foes to ensure his survival!

How to Use, Explanation

Emblem Sigurd's base kit is good enough to be used immediately after summoning. He makes great use of Emblem Sigurd Ring to expand his movement and increase his Canto ability to keep him safe.

Emblem Byleth (M) Weaknesses

Low Magical Bulk

Emblem Byleth (M)'s low base 17 Res paired with an average base 40 HP leaves him vulnerable to magic damage. Any attack from a decently powerful magical attacker can potentially defeat Byleth in one round.

As a pseudo-refresher unit, Emblem Byleth (M) can be kept safe from enemies by using his abiltiy to refresh ally's turns. Nevertheless, keep Byleth away from enemies that deal magical damage to ensure his survival.
