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.

+Atk/-Res

The best IVs for Frederick are +Atk and -Res. A +Atk IV maximizes the damage 1.5x damage multiplier his weapons against armored units. As mainly an offensive unit whose job is to match-up with armored foes, increasing damage is a no-brainer so you should take this IV whenever possible. Spend Trait Fruits if you need to!

His Res is very low and is of less importance so it is safe to take as a bane.

+Atk for a +10 Merge

We recommend a +Atk IV when merging Frederick to 10. This is for the same reasons as above. With +10 merges and his special weapon refine, he can take out lots of armored units in one hit!

Frederick Best Builds

Brave Frederick

HOT
： Brave Axe+ ： Draw Back ： Bonfire ： -	： Death Blow 4 ： Drag Back ： Hone Cavalry ： Attack +3 ： -

How to Use, Explanation

This build utilizes Frederick's raw damage output to quick take out enemy units before retreating to safety. Since he already has poor speed, Brave Axe+ is a good weapon for him to use.

Offensive Refine Frederick

HOT
： Frederick's Axe ： Reposition ： Ignis ： -	： Death Blow 4 ： Lull Spd/Def 3 ： Panic Smoke 3 ： Death Blow 3 ： -

How to Use, Explanation

This build makes use of Frederick's +Eff refine and multiple instances of Death Blow in order to obliterate enemy units, especially if they're armored. He will also be able to hit harder with Lull Spd/Def and debuff enemies with Panic Smoke after combat.

Frederick Best Weapon Refine

Effect of Frederick's Refined Weapon

Exclusive Weapon Effect from Refining (Special Effect Type)
Frederick's Axe	SP: 400
Might: 16　Range: 1　HP: +3 Effective against armored foes. If unit initiates combat, grants Atk+6 during combat. ：500　：200

We recommend the Special Effect Refine for Frederick's Axe

It is a straightforward upgrade that grants Frederick an effect identical to Death Blow 3. This raw player phase damage allows him to deal huge damage to armored units as the bonus will be effectively +9 Atk against them. Of course, the +6 Atk against any other unit is not negligble.

Be sure to get this upgrade if you need a good match-up against blue armored units like Legendary Tiki (Young) and Effie. Of course Tiki will deal heavy damage to him, so make sure to get to her before she gets to Frederick.

Frederick Roles, Strengths, and Weaknesses

Frederick Roles

Frederick - Polite Knight 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

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.

Frederick Strengths

High Atk and Def stats!

Frederick's Atk and Def are at a base 35 and 36. This makes him a solid match-up to physical units. His Atk stat synergizes well with the default effect and special refine effect of Frederick's Axe as the weapon grants him effective damage to armored units and an effect identical to Death Blow 3! We recommend increasing his Atk and Def further by inheriting skills like Death Blow 4 or Fury 4.

You can also build him around cavalry units that possess skills like Hone Cavalry and Ward Cavalry to further boost his statline.

Dishes out heavy damage to armored foes

Frederick's weapon skills Hammer+ and the more powerful Frederick's Axe deals a ton of damage to armored units. Being able to plow through high defense units could be said to be his strength when using these weapons.

Can warp to allies who are in a pinch

His B skill Wings of Mercy 3 will let him warp to any ally with less than 50% HP. Frederick's high mobility is further supplemented by this skill. This makes him very useful in maps like Rival Domains and Grand Conquests where there are lots of allied units spread out in the map.

Def buff to allies

At the start of every turn, Fortify Def 3 grants +4 Def to adjacent allies. Though we suggest getting a better C skill like Hone Cavalry, know that base Frederick can buff his allies Def using this skill. This might be the difference between victory or defeat in harder battles.

Frederick Weaknesses

Low Res

Frederick's Res only sits at 14 at Lv.40. This makes it easy for magic users to take him out. Be mindful of Frederick's positioning in relation to magical units that can easily take him out. Use his high mobility to pick match-ups that are advantageous for him as his Def is around 3x is Res stat. Leave magic units to Frederick's allies so he can focus his firepower on other enemies.

Low Spd

Frederick has very low Spd. This makes him susceptible to follow-up attacks. Despite his high Def, if he is hit by something like a Moonbow-boosted follow-up attack, he can still be taken out if not take huge damage as said special lowers his Def by a percentage.

You can inherit a skill like Quick Riposte 3 to allow him to score follow-up attacks in the enemy phase. Check out the builds section to find out more.
