Ferox Chulainn Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (19) Normal HP ★★★★☆
Atk (11) No Attack IV ★★★★☆
Spd (9) Spd Boon ★★★★★
Def (11) No Def IV ★★★☆☆
Res (8) Res Boon ★★☆☆☆

◯ = 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 / -Res

The best IVs for Ferox Chulainn are +Spd and -Res. Ferox Chulainn's base 48 Spd, raised to 52 with a superboon, is among the highest in the game. Due to his lack of an exclusive skill, he will need to maximize his stats to even compete with modern metagame units.

Res is Ferox Chulainn's least important stat and can be safely taken as a bane as it won't impact any of his matchups.

+Spd for a +10 merge

We recommend +Spd when merging Ferox Chulainn up to +10 to ensure he can keep up with all the fast metagame units.

Ferox Chulainn Roles, Strengths, and Weaknesses

Ferox Chulainn is a close physical attacker (range = 1). 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.

Ferox Chulainn Strengths

Arena Axe+ inflicts Spd Shackle and Def Shackle

Ferox Chulainn's inheritable Arena Axe+ inflicts Spd/Def-7, 【Spd Shackle】, and 【Def Shackle】 on closest foes and foes within 2 spaces of those foes at the start of each turn and after each of Chulainn's actions.

In combat, Arena Axe+ grants Ferox Chulainn Atk/Spd/Def/Res+5, bonus true damage equal to 20% of his Spd, and bonus true damage reduction from foe's first attack equal to 20% of his Spd.

While not as impactful as exclusive weapons released recently, Arena Axe+ is still quite good and is worth inheriting onto your favorite units that don't have exclusive weapons.

Ferox Chulainn Weaknesses

Lack of Unique Skills

Ferox Chulainn suffers from not having any unique skills to call his own, making him unable to stand out amongst other units.

Axe Infantry units are quite abundant in the game, and lacking an exclusive weapon makes Ferox Chulainn replaceable by better units.
