Arval Best IVs

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (18)		★★★☆☆
Atk (11)		★★★★★
Spd (5)		★★☆☆☆
Def (4)		★★☆☆☆
Res (13)		★★★★★

◯ = 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.

+Res / -Def

The best IVs for Arval are +Res and -Def. A Res superboon improves their performance as a magic wall, makes Rite of Souls' Res check more reliable, and also increases their damage output through the true damage effect.

Their Def is below average and is prone to being defeated by physical attackers. Thus, it is a safe bane to take.

+Res for a +10 Merge

We recommend +Res when merging Arval up to +10 for similar reasons above. Arval's performance relies on a Res check, and improving their Res makes him more reliable.

Arval Roles, Strengths, and Weaknesses

Arval Roles

Arval - Cycle Keeper 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

Arval is a ranged magic attacker (range = 2). Therefore, when not accounting for the Weapon Triangle, the amount of damage they deal will be equivalent to their Atk minus the foe's Res stat.

Arval Strengths

Rite of Souls has multiple effects

Arval's Rite of Souls accelerates their Special trigger, inflicts 【Guard】 on all enemies within 3 columns or 3 rows centered on Arval at the start of turn, grants Atk/Spd/Def/Res+5 to Arval during combat, deals true damage equal to 20% of Arval's Res, and denies their foe's follow-up attacks.

While none of these effects are gamebreaking, they are all impactful in their own way. All of these effects bundled up into one weapon make Arval a formidable unit for your team.

Duality provides a unique effect

Arval's exclusive A skill Duality has a unique effect which grants Arval weapon-triangle advantage against red, blue, and green foes, and disables skills that affect weapon-triangle calculations like Triangle Adept 3 and Cancel Affinity 3..

On top of the weapon-triangle effects, Duality also grants Arval a flat Atk/Res+9 with no drawbacks and grants Arval a guaranteed follow-up attack during combat.

This skill makes matching up against Arval quite difficult, especially if there are no colorless units to face them directly in combat.

Arval Weaknesses

Rite of Souls has conditional effects

Rite of Souls has two different conditions that can affect Arval's performance in battle.

The 【Guard】status infliction relies on both Arval winning a Res check and being in its range, while the other effects require Arval to either initiate combat or be within 2 spaces of an ally.

Careful planning will be required when positioning Arval to ensure their weapon triggers all of its effects.

Low Def

Arval's Def stat is only at a base 23, which leaves them vulnerable to physical damage attackers.

Keep them out of range of these units to ensure they remain alive.
