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, Summer Dedue will always have neutral IVs by default. The only way to access IVs for this unit is through using Trait Fruits.

+Def / -Spd

The best IVs for Summer Dedue are +Def and -Spd. Def is a superboon and improves Summer Dedue's performance as a physical tank, which is his primary role. The superboon increases his base Def to 51, making it one of the highest base Def stats in the entire game.

Summer Dedue's Spd is a dump stat at only base 20, and no amount of investment will be able to salvage this stat to make it competitive against other heroes. It is a safe bane to take.

+Def for a +10 merge

We recommend +Def when merging Summer Dedue up to +10 to maximize his physical tanking prowess, allowing him to soak up physical damage even against maximum investment heroes.

Summer Dedue Roles, Strengths, and Weaknesses

Summer Dedue Roles

Dedue - Loyal Life Guard 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

Summer Dedue 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.

Summer Dedue Strengths

Anchor Axe+ boosts Atk/Def and has a Guard effect

Summer Dedue's inheritable Anchor Axe+ can create a large Atk/Def bonus during combat, up to Atk/Def+20, boosting Dedue's two most important stats by a large margin. It also inflicts Special cooldown charge -1 on Dedue's foe per attack during combat, preventing them from progressing their Special cooldown counts.

While not as powerful as other exclusive or Arcane axes, Anchor Axe+ provides just enough where it can be useful on the right heroes.

Great Overall Bulk

Summer Dedue has high defensive stats with his base 45 HP, 47 Def, and 35 Res. His primary role with this statline is a physical tank, soaking up physical damage for the team.

His magical bulk is still quite good, allowing Summer Dedue to survive an attack or two from magical foes.

Summer Dedue Weaknesses

Low Spd

Summer Dedue's Spd is nearly unsalvageable at only base 20, opening him up to receiving follow-up attacks from most foes.

Without a way to prevent follow-up attacks, reduce incoming damage, or sustain himself through recovery, Summer Dedue will be gradually worn down through attrition.

Lack of Unique Skills

Summer Dedue 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, especially among Heroic Grail units, and lacking an exclusive weapon makes Summer Dedue replaceable by better units.
