Sage Byleth (M) Skills at 5★

Guide's Hourglass Might: 14　 Range: 2 Accelerates Special trigger (cooldown count-1). At start of turn, if unit is within 2 spaces of an ally, grants "unit cannot be slowed by terrain (does not apply to impassable terrain)" and 【Dodge】 to unit for 1 turn. If unit initiates combat or is within 2 spaces of an ally, grants Atk/Spd/Def/Res+5 to unit and neutralizes effects that grant "Special cooldown charge +X" to foe or inflict "Special cooldown charge -X" on unit during combat. If unit is within 2 spaces of any allies, grants Atk/Spd/Def/Res+4 to those allies during combat.

Sublime Heaven Cooldown Count = 2 Boosts damage by 25% of unit's Atk. If in combat against a dragon foe or beast foe, boosts damage by 50% instead of 25%. Disables non-Special skills that "reduce damage by X%".

Spd/Res Finish 3 If unit is within 3 spaces of an ally, grants Spd/Res+6 to unit during combat, and also, if unit's Special is ready or unit's Special triggered before or during this combat, deals +5 damage during combat. (Except when dealing damage with area-of-effect Specials.)

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.

Stat	Superboon/Superbane	IV Recommendation
HP (18)		★★★☆☆
Atk (12)		★★★★☆

Def (3)		★★☆☆☆
Res (4)		★★★☆☆

◯ = 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 / -Def

The best IVs for Sage Byleth (M) are +Spd and -Def. His base Spd is really high at base 44, and the 【Dodge】 status improves his bulk through the damage reduction effect.

His defensive stats are below average and any of them can be taken as a bane. We recommend Def since it is the lowest among the three.

+Spd for a +10 merge

We recommend +Spd when merging Sage Byleth (M) to +10 to maximize his Spd and ensure she gets the best chance to survive through his damage reduction effect.

Sage Byleth (M) Roles, Strengths, and Weaknesses

Sage Byleth (M) Roles

Byleth - Fount of Learning 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

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

Sage Byleth (M) Strengths

Guide's Hourglass ignores terrain penalties, grants Dodge, Tempo, stat bonuses to himself, and stat bonuses to his allies

Sage Byleth (M)'s exclusive weapon Guide's Hourglass accelerates Special trigger and ignores terrain penalties like all the other weapons for the heroes on his debut banner.

It also grants Byleth 【Dodge】, Atk/Spd/Def/Res+5 during combat, the Tempo effect, and Atk/Spd/Def/Res+4 to all nearby allies during combat.

The accelerated Special trigger and Tempo effect ensure that Byleth can trigger his Special, Sublime Heaven, very often.

Sublime Heaven pierces damage reduction and has extra damage against dragons and beasts

Sage Byleth (M) also carries Sublime Heaven like his Legendary counterpart.

Sublime Heaven is a 2 charge special, lowered to 1 with Guide's Hourglass, that increases Byleth's damage by 25% of his attack, and 50% if Byleth is facing a dragon or beast foe. In addition to that, it negates foe's non-Special skills that reduce damage such as Spurn 3 or Fallen Edelgard's Armored Wall.

This exclusive Special is still one of the most powerful Special skills in the game despite its age.

Easy to merge

Being a 4 star special hero on his debut banner, Sage Byleth (M) is cheap to merge up by acquiring copies at an increased rate compared to other 5 star exclusive heroes.

Sage Byleth (M) is arguably one of the best 4 star special heroes in the entire game, only rivalled by Summer Claude.. He has two powerful exclusive skills and a modern statline capable of fighting the top tier units in the metagame.

Sage Byleth (M) Weaknesses

Guide's Hourglass requires ally proximity

Guide's Hourglass only grants the terrain bonus and Dodge if Sage Byleth is within 2 spaces of an ally at the start of his turn.

Additionally, he also only receives the Tempo effect and stat bonuses if he either initiates combat or is within 2 spaces of an ally.

Careful positioning is necessary in order to bring out the best in Sage Byleth (M).

Sage Byleth (M) as a Source Hero

Value of Skills	★★★★☆

Sage Byleth has Spd/Res Finish 3 and Lull Spd/Res 3 as inheritable options.

While his fodder is good, we suggest merging him up instead, as copies of Sage Byleth (M) are easier to acquire due to his 4 star rarity.
