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.

Neutral IVs by default!

As a hero obtainable only through Tempest Trials, Young Frederick will always have neutral IVs by default. The only way to access IVs for this unit is through using Trait Fruits.

+Def / -Res

The best IVs for Young Frederick are +Def and -Res. Def is a superboon and boosts his already impressive Def up to base 51, allowing him to excel at tanking physical damage.

His Res is a clear weakness at only base 23 and no amount of investment will protect him against magic damage. Res is a safe bane to take.

+Def for a +10 merge

We recommend +Def when merging Young Frederick up to +10 to improve his physical tanking prowess even further.

Young Frederick Roles, Strengths, and Weaknesses

Young Frederick Roles

Frederick - Youth in Service 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

Young Frederick 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.

Young Frederick Strengths

Heavy War Axe grants Bonus Doubler and follow-up denial to unit and allies

Young Frederick's Heavy War Axe grants Atk/Def+6, 【Bonus Doubler】, and a status effect that grants foe follow-up denial to himself and either his support partner or (if the support partner isn't present) the ally with the highest Def within 2 spaces.

In combat, Heavy War Axe grants Frederick Atk/Spd/Def/Res+5, a guaranteed follow-up attack, bonus damage equal to 20% of his Def, and 30% damage reduction on his foe's attacks.

These effects make Frederick a very sturdy physical tank while also being able to dish out good damage at the same time.

Young Frederick Weaknesses

Low Spd and Res

Young Frederick's Spd is middling at only base 28, and his Res is even worse at only base 23. These low stats leave him vulnerable to magic damage, especially from fast foes that can create follow-up attacks against him.

Even his damage reduction effect will not be able to protect Frederick from modern magical attackers.

Weak to Cavalry Effective Weapons

Young Frederick takes 1.5x damage from cavalry-effective weapons like Thani or Binding Reginleif, and one blow from this type of weapon will deal significant damage. Make sure you know what weapons you are up against before hopping too far into the line of battle!
