Duo Ephraim Best IVs

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (19)		★★★☆☆
Atk (28)		★★★★★
Spd (8)		★★★☆☆
Def (9)		★★★★☆
Res (6)		★★☆☆☆

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

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.

+Atk/-Res

Duo Ephraim's best IVs are +Atk and -Res. With his superboon in Atk, he gains an additional +4, making the guaranteed follow-up effect of Reginleif even easier to trigger. A bane in HP or Spd would give him -4 in either stat, so Res is the more ideal bane.

+Atk for a +10 Merge

If you are building a +10 merge of this unit, we recommend +Atk. As Ephraim's weapon skill already lets him gain a guaranteed follow-up, there is no reason to go for +Spd, unless you aim to also prevent as many follow-up attacks from foes as possible. Once again, with the increased effectiveness from his weapon skill and strength from each attack factored in, +Atk is probably the best choice.

Duo Ephraim Best Weapon Refine

Effect of Duo Ephraim's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
Reginleif	SP: 400
Might: 16　Range: 1　HP: 3 Effective against armored and cavalry foes. Grants Atk +3. Unit cannot be slowed by terrain. (Does not apply to impassable terrain.) At start of combat, if unit’s Atk > foe’s Atk or if 【Bonus】 is active on unit, grants Atk/Spd/Def/Res+4 to unit during combat. During combat, if unit’s Atk > foe’s Atk or if 【Bonus】 is active on unit, unit makes a guaranteed follow-up attack. If 【Bonus】 is active on unit, enables 【Canto (Rem. +1)】. At start of even-numbered turns, unit can move 1 extra space. (That turn only. Does not stack.) At start of combat, if unit’s HP ≥ 25%, grants Atk/Spd/Def/Res+4 to unit during combat, and if 【Bonus】 is active on unit, foe cannot make a follow-up attack. ：500　：200

We recommend the Special Effect Refine for Reginleif

Refined Reginleif allows Duo Ephraim to not be hindered by terrain, grants bonus stats, a guaranteed follow-up attack, Even Tempest 3, 【Canto (Rem. +1)】, and denies his foe's follow-up attack.

These are all great effects, and stacking all of them onto one weapon makes Duo Ephraim a very powerful unit.

Duo Ephraim Roles, Strengths, and Weaknesses

Duo Ephraim Roles

Ephraim - Dynastic Duo 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

Duo Ephraim is a close physical attacker (Range = 1). When the effects of the Weapon Triangle are not taken into account, the damage he deals will be equal to his Atk minus the foes's Def.

Duo Skill Usable in Arenas

Ephraim's Duo Skill raises his arena score, in addition to granting him a powerful battle effect. Duo Heroes have a Duo Skill which can be used once per map. Additionally, his Duel effect treats his stats as 185 in Arena modes, giving him a huge advantage over many other heroes.

The effect of Ephraim's Duo Skill is shown below

Infantry and armored allies within 2 spaces of unit (including unit) can move 1 extra space. (That turn only. Does not stack.)
(Duo Skills can be used once per map by tapping the Duo button. Duo Skills cannot be used by units deployed using Pair Up.)

Standard Effect 1: Duel
If unit is 5★ and level 40 and unit's stats total less than 185, treats unit's stats as 185 in modes like Arena. (Higher-scoring opponents will appear. Stat total calculation excludes any values added by merges and skills.)

Duo Ephraim Strengths

Duo Skill adds +1 to movement

Duo Ephraim has a powerful Duo skill, which will grant +1 movement to both him and nearby infantry/armored allies. On top of being able to support his allies and increase the range in which he can move for a turn, this also allows the effects of his weapon Reginleif to trigger, making it extremely useful.

Weapon is effective on two types and grants follow-up attacks

Duo Ephraim's exclusive weapon skill Reginleif is effective on armored and cavalry units, allowing him to deal massive damage to these types of foes. Additionally, when his Atk exceeds that of the foe, OR he has been granted extra movement (via his Duo Skill, etc.), he will gain a guaranteed follow-up attack, which greatly extends his offensive capability. You can easily buff his Atk further through seals or skills, making this unit very powerful thanks to how easy it is for him to deal heavy damage in this way.

Nullifies enemy bonuses while casting a penalty

Ephraim's B skill Lull Atk/Def 3 will nullify active enemy bonuses, and simultaneously inflict Atk/Def-3. This skill is great for cancelling out skills like Fortify or Rally and increasing the damage Ephraim can output in combat while reducing the damage he takes, but keep in mind that it will have no effect on Drive/Spur bonuses.

Duo Ephraim Weaknesses

Struggles against magic

Duo Ephraim has a rather low Res stat, so he will take lots of damage from magic attackers. Additionally, his Spd stat is pretty subpar, so he takes many follow-up attacks too. A speedy dragon or magic and easily sweep him, so be sure and observe the range of your foes and stay far away from magic attackers who could wipe him out.
