Arlen Skills at 5★

Lightburst Tome Might: 14　 Range: 2 Accelerates Special trigger (cooldown count-1). At start of turn, if unit's HP ≥ 25%, grants Atk/Spd/Def+6 and "unit cannot be slowed by terrain (does not apply to impassable terrain)" to unit and allies within 2 spaces of unit for 1 turn. At start of combat, if unit's HP ≥ 25%, and if unit's attack can trigger unit's Special, grants Special cooldown count-1 to unit before unit's first attack during combat. At start of combat, if unit's HP ≥ 25%, inflicts Atk/Spd/Res-X on foe during combat (X = 16, - foe's max Special cooldown count value x 2; min 8; if foe does not have a Special skill, X = 8). At start of combat, if unit's HP ≥ 25%, reduces damage from foe's first attack by 30% and unit's next attack deals damage = total damage reduced (by any source, including other skills; resets at end of combat), and restores 7 HP to unit after combat.

Ignis Cooldown Count = 4 Boosts damage dealt by 80% of unit’s Def.

C Bonus Doubler Unit can counterattack regardless of foe's range. Grants Atk/Spd/Def/Res+X to unit during combat (X = highest bonus on each stat between unit and allies within 2 spaces of unit; calculates each stat bonus independently).

Atk/Res Tempo 4 Inflicts Atk/Res-4 on foe, neutralizes effects that grant "Special cooldown charge +X" to foe or inflict "Special cooldown charge -X" on unit, and reduces the percentage of foe's non-Special "reduces damage by X%" skills by 50% during combat (example: a foe with a "reduces damage by 45%" skill would reduce damage by 23% instead).

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (19)		★★★☆☆
Atk (9)		★★★★☆

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

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.

+Def / -Res

The best IVs for Arlen are +Def and -Res. Arlen's Def is a superboon and boosts it up to base 42, allowing him to fulfill a secondary role as a physical tank on top of his primary offensive role.

Arlen's Res is quite abysmal at only base 17, and no amount of investment will protect him against a good magic damage attacker. Taking Res as a bane is his best option.

+Spd for a +10 merge

We recommend +Spd when merging Arlen up to +10 in order to protect himself from follow-up attacks against the fastest metagame foes. +Def is also an option if preferring to invest into bulk instead.

Arlen Roles, Strengths, and Weaknesses

Arlen Roles

Arlen - Mage of Khadein 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

Arlen 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.

Arlen Strengths

Lightburst Tome grants unhindered movement

Arlen's Lightburst Tome grants Atk/Spd/Def+6 and an Unhindered Movement effect to himself and nearby allies at the start of each turn. This effect allows unit to traverse through passable terrain without getting movement restrictions, such as moving through trees for infantry units and moving through trenches for cavalry units.

In combat, Lightburst Tome inflicts Atk/Spd/Res penalties onto his foe based on their maximum Special cooldown count, grants Arlen Special cooldown count-1 before his first attack, 30% damage reduction on his foe's first attack, damage reflection based on the damage reduced, and 7 HP post-combat healing.

These effects all add up to make Arlen a formidable unit when in combat, dealing a good chunk of damage while providing sustain and bulk to survive difficult engagements.
