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.

Neutral IVs by default!

As a hero obtainable only through Grand Hero Battle, Cyril will always have neutral IVs by default. The only way to access IVs for this unit is through using Trait Fruits.

+Spd / -Res

The best IVs for Cyril are +Spd and -Res. Cyril's base Spd is at base 44 and is high enough to compete with fast metagame units and avoid follow-ups from faster units.

Res is Cyril's least important stat at only base 26 and can be safely taken as a bane.

+Spd for a +10 merge

We recommend +Spd when merging Cyril to +10 as it is his best stat both offensively and defensively.

Cyril Roles, Strengths, and Weaknesses

Cyril Roles

Cyril - Rhea's Attendant 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

Cyril is a ranged physical 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 Def stat.

Cyril Strengths

Aptitude Arrows grants bonus stats, true damage, and neutralizes penalties

Cyril's Aptitude Arrows grants Atk/Spd/Def/Res+10 at Level 40, true damage equal to 20% of his Spd, and neutralizes Cyril's penalties during combat.

This unique colored bow provides ample offensive effects to break through most enemies.

Cyril Weaknesses

Competition

While Cyril has good offensive stats and a usable exclusive weapon, he still faces stiff competition from other bow infantry units with more unique effects.

Units like Valentine's Chrom and Legendary Chrom have extra exclusive skills on their kits, while units like Legendary Alm have more effects tied to their weapon.

Additionally, there are already two Arcane bows released in Arcane Náströnd and Arcane Darkbow, opening up improved and competitive weapons for mergeable bow units.

While the competition doesn't exactly make Cyril obsolete, as he is still a good unit on his own with a modern statline, it makes it more difficult to fit another infantry bow unit onto specific teams.
