Idunn Skills at 5★
|
Might: 16 Range: 1 Def+3. Effective against armored foes. At start of combat, if a penalty is active on unit, or unit’s HP< 100%, neutralizes penalties on unit and grants Atk/Spd/Def/Res+4 in combat. Calculates damage using the lower of foe’s Def & Res if foe’s range=2 |
|
Cooldown Count = 3 Boosts damage dealt by 50% of unit’s Def. |
|

◯ = 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.
+Res/-Spd
Idunn's best IVs are +Res and -Spd. With a super boon in Res, an asset in this stat gives Idunn +4 Res, making her an incredible magic wall. As a bane, HP or Spd are ideal. A Spd bane will increase the follow-up attacks she receives, but speed up her special cooldown quicker.

How to Use, Explanation
This build revolves around inheriting Distant Counter so Idunn can counterattack from any range. With Bold Fighter in the B slot, Idunn can get guaranteed follow-up attacks when initiating combat, and through Quick Riposte, when the foe initiates combat as well. In the C slot, we chose Armor March to raise her mobility.
Idunn Best Weapon Refine
Effect of Idunn's Refined Weapon
| Exclusive Weapon Effect from Refining (Special Effect Type) | |
|---|---|
| SP: 400 | |
| Might: 16 Range: 1 HP: 3 Grants Def+3. Effective against armored foes. If foe initiates combat, if a negative status effect is active on unit at start of combat, or if unit's HP < 100% at start of combat, neutralizes penalties on unit and grants Atk/Spd/Def/Res+4 during combat. If foe's Range = 2, calculates damage using the lower of foe's Def or Res. If foe initiates combat or if foe's HP ≥ 75% at start of combat, grants Atk+5 to unit, inflicts Atk-5 on foe, and also, if foe can make a follow-up attack, reduces damage from foe's first attack by 70% during combat.  ：500  ：200 |
|
We recommend the Special Effect Refine for Demonic Breath
Refined Demonic Breath grants Idunn bonus Atk, reduces her foe's Atk, and grants a massive 70% damage reduction if her foe can make a follow-up attack.
This refine turns Idunn into a very potent wall that can withstand multiple blows from her enemies.

Idunn Roles, Strengths, and Weaknesses
Idunn Roles
Idunn is a non-ranged (Range = 1) magic attacker. Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent to her Atk minus the foe's Res stat.
Idunn Strengths
Demonic Breath has useful effects
Idunn's unique weapon Demonic Breath provides some useful effects that function both offensively and defensively.
Below is a summary of its effects:
| 1 | Grants Def+3 |
|---|---|
| 2 | Effective against armored foes |
| 3 | Neutralizes penalties on Idunn, if a penalty is active on her or her HP < 100% |
| 4 | Grants Idunn Atk/Spd/Def/Res+4 during combat, if a penalty is active on her or her HP < 100% |
| 5 | Calculates damage using the lower of foe's Def or Res, if foe's Range = 2 |
Can play a support role in a Dragon party
Even among other armored manaketes, Idunn is exceptionally powerful, and she can excel as a pivotal member in both all armor or all dragon teams. Since she learns Ward Dragons by default, she can easily buff the defensive power of other dragons in her team to play a support role.
Bold Fighter and Vengeful Fighter are both very powerful on Idunn!
As an armor unit, equipping skills like Bold Fighter and Quick Riposte as Sacred Seals will allow her to gain follow-up attacks regardless of who initiates combat. However, Bold Fighter is quite a high investment skill, and Vengeful Fighter alone is quite powerful as is, so do not waste extremely valuable skills unless necessary.
Works well with teammates who have movement skills
In a Dragon party, Idunn will often be slowed by her low mobility, so having a teammate with Armor March or Guidance on the same team will make it easier for her to get up and close to the foes. Guidance is also available as a Sacred Seal.
Idunn Weaknesses
Watch out for enemy follow-up attacks! Do not overestimate her defensive power
Although Idunn's defensive stats are very high, her Spd is slow, meaning she will often take follow-up attacks, and if taken from a blue unit, that damage will add up quickly. In particular, Idunn does not have Distant Counter by default, so a speedy blue ranged unit can deal plenty of damage to Idunn. Units like Micaiah who have effective weapons, and speedy attackers like Ishtar are equipped to take Idunn down, so know your enemy's unit types, and let her allies take out foes she struggles with.

Inheriting Fort. Def/Res 3 or Vengeful Fighter 3
Idunn can be used to inherit the skills Fort. Def/Res 3 or Vengeful Fighter 3. However, Idunn is a rare and extremely powerful armored dragon unit, so we highly recommend keeping and building at least one before foddering of or merging any duplicates. In addition, she works great in both dragon and armor parties.
