Idunn - Divine Demon: Basic Information

Color / Weapon Type / Move Type
Rarity
What Kind of Character Are They? ・Dew Dragonstone accelerates Special trigger, is effective against armored units, nullifies weapons that are effective against armored units, inflicts debuffs on enemy units during combat, and also prevents enemy units from making follow-up attacks.

Ascended Idunn Skills at 5★


Might: 16  Range: 1
Accelerates Special trigger (cooldown count-1). Effective against armored foes. Neutralizes "effective against armored" bonuses. If unit is within 3 spaces of an ally, inflicts Atk/Spd/Def/Res-5 on foe during combat, neutralizes penalties on unit during combat, and foe cannot make a follow-up attack. If foe's Range = 2, calculates damage using the lower of foe's Def or Res.

Cooldown Count = 3
Boosts damage dealt by 50% of unit’s Def.

If foe initiates combat, grants. Atk/Def +6 during combat and inflicts Special cooldown charge -1 on foe per attack. (Only highest value applied. Does not stack.)

If unit's HP ≥ 25% and foe initiates combat, neutralizes bonuses (from skills like Fortify, Rally, etc.) on foe during combat and unit makes a guaranteed follow-up attack.

If a foe uses sword, lance, axe, breath, or beast damage & initiates combat against an ally with 2 spaces of unit, triggers【Savior】on unit.
If Savior triggers, grants Def/Res+4 during combat.
【Savior】
Unit takes ally’s space, enters combat in ally’s place, and receives all after-combat effects.
Doesn't trigger if ally is on terrain that unit can't move to or if multiple units are able to use Savior during the same combat. If Savior triggers, after-combat movement effects don't occur.

Ascended Idunn Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (15) HP Superboon ★★★★☆
Atk (10) Attack Bane ★★★★★
Spd (7) Spd Boon ★★☆☆☆
Def (10) Def Bane ★★★★★
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.

+Def/-Spd

Ascended Idunn's best IVs are +Def/-Spd. A defense boon increases her bulk, keeping her Near Save skill active throughout more engagements.

A +Res IV is also good on Idunn in order to opt for more generalized bulk. It is also a superboon.

Her Spd is in the awkward area where she is faster than the slow metagame units, but slower than the speedy metagame units. Thus, it is safe to take as a bane, as it shouldn't affect most of her matchups.

+Def for a +10 merge

For a fully invested Ascended Idunn with +10 merges and +5 dragonflowers, a +Def IV works well for similar reasons above. Same with +Res to balance out her overall bulk.

A +Spd IV also works if you prefer a fast Idunn build. This option allows Ascended Idunn to minimize follow-up attacks from opponents who can negate her follow-up denial effect.

Ascended Hero Bonus

As an Ascended Hero, Idunn can ascend one of her stats for free without using an Ascendant Floret! We recommend +Def or +Res, whichever IV you did not take.

Ascended Idunn Best Builds

Near Save Tank Ascended Idunn

HOT
Assist Skill IconSwap
Updated on 05/07/2025

How to Use, Explanation

This is a Near Save build for Ascended Idunn using modern skills. Emblem Eirika ring increases the chances of Idunn defeating her foe in retaliation, while Deflect Melee 3 provides damage reduction against enemies with Desperation effects which are quite common in the modern metagame.

Far Save Tank Ascended Idunn

HOT
Assist Skill IconSwap
Updated on 05/07/2025

How to Use, Explanation

This is a Far Save variant of the build above. Hardy Bearing 3 disables Desperation effects which are common in today's metagame, while Emblem Eirika ring grants a brave effect that can allow Idunn to defeat her foe in retaliation. We chose Hardy Bearing over Deflect Missile mostly to counter Emblem Lyn.

Shield Fighter Tank Ascended Idunn

HOT
Assist Skill IconSwap
Special Skill IconAegis
Updated on 05/07/2025

How to Use, Explanation

This build uses Shield Fighter to soak damage instead of aiming to retaliate with damaging attacks from Dragon's Roar or Armored Specials.

Near Save / Budget Ascended Idunn

Assist Skill IconSwap
Special Skill IconBonfire
Emblem Icon: -
Attuned Skill Icon: -

How to Use, Explanation

This is a budget Near Save build using Idunn's base kit. While this won't be enough in PvP modes, it can still do a decent job outside of those.

Ascended 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.

Ascended Idunn Strengths

Dew Dragonstone is a very powerful weapon!

Dew Dragonstone Bonfire Attack

Ascended Idunn melts the Sword Knight with her Dew Dragonstone and Bonfire!

Dew Dragonstone is a very powerful weapon which is very similar to the infamous refined Maltet of the menace known as Brave Hector.

Listed below are all of its effects:

1 Accelerates Special trigger (cooldown count -1).
2 Effective against armored foes.
3 Neutralizes "effective against armored" bonuses.
4 Inflicts Atk/Spd/Def/Res-5 on foe during combat, if Ascended Idunn is within 3 spaces of an ally.
5 Neutralizes penalties on Ascended Idunn during combat, if Ascended Idunn is within 3 spaces of an ally.
6 Foe cannot make a follow-up attack, if Ascended Idunn is within 3 spaces of an ally.
7 Calculates damage using the lower of foe's Def or Res, if foe's Range = 2.

Similar to Brave Hector's refined Maltet, Dew Dragonstone has the following effects:

  • Accelerated Special trigger
  • Neutralizes "effective against armored" bonuses
  • Neutralizes penalties on unit during combat
  • Foe cannot make a follow-up attack
  • Applies debuffs to the foe during combat (Maltet applies Atk/Def-6, Dew Dragonstone applies Atk/Spd/Def/Res-5)

One notable effect that is present on refined Maltet but absent on Dew Dragonstone is the guaranteed follow-up attack. However, this effect is present on Ascended Idunn's B skill, Wily Fighter 3.

Dew Dragonstone also has effects that are not given by refined Maltet. It is effective against armored foes, and it applies magic damage to melee foes and adaptive damage to ranged foes.

Take note, however, that Dew Dragonstone only neutralizes armor effectiveness. it does not neutralize dragon effectiveness.

Ascended Idunn's passive skills work well with Dew Dragonstone!

Ascended Idunn comes with three passive skills: Sturdy Stance 3, D/R Near Save 3, and a newly released skill - Wily Fighter 3.

Sturdy Stance 3 grants Idunn Atk/Def+6 during combat and applies a Guard effect to the foe.

D/R Near Save 3 grants Idunn Def/Res+4 during combat and allows her to intercept melee attacks made towards allies within 2 spaces of her.

During enemy phase, if Idunn's HP ≥ 25%, Wily Fighter 3 neutralizes her foe's bonuses during combat and grants Idunn a guaranteed follow-up attack.

Ascended Idunn Weaknesses

Mediocre Speed

Ascended Idunn's Spd stat is in the awkward range where she is faster than slow metagame units, but slower than fast metagame units.

This can affect her defensively through receiving follow-up attacks from heroes with partial or full Null Follow-Up effects.

This can also affect her offensively if the opponent has Spd based damage reduction from skills like Spurn 3.

However, Idunn's Spd is a superboon, and it is possible to stack enough Spd to mitigate her weaknesses.

Weak to Dragon Effective Weapons

Ascended Idunn takes 1.5x damage from dragon-effective weapons like Thrasir's Ífingr or Legendary Julia's Virtuous Naga, and one blow from this type of weapon is sure to inflict heavy damage onto Ascended Idunn, or outright kill her. Make sure you know what weapons you are up against before hopping too far into the line of battle!

Ascended Idunn as a Source Hero

Ascended Idunn Avatar

Value of Skills ★★★★★

Ascended Idunn has three very valuable skills to provide for skill inheritance: Sturdy Stance 3, Wily Fighter 3, and D/R Near Save 3.

As of February 2022, Wily Fighter 3 is unique to Ascended Idunn. Both D/R Near Save 3 and Sturdy Stance 3 can be obtained from other heroes.

Ascended Idunn is a very powerful unit; think carefully before you decide to fodder her off.

Just pulled her from the weekly ticket from arena, so came to see what y'all thought about her. There's no way she should have the same rating as bridal sharena. I know they're different types of units, but take even Marni (who is an armor unit, but of a different weapon & color). There's no way they should be rated the same, IMO. Maybe it's just in regards to her specific color, movement type & weapon? 🤷🏼‍♂️ Still hard to justify, IMO.
