This build aims to take advantage of Idunn’s optimized statline and turn her into a devastating Enemy Phase threat, helped further by her Duo skill, which grants her and all allies within 5 rows and 5 columns immunity to Dragon-Effective damage for a turn while granting her an additional 6 Defense and Resistance.
Noontime and Aether are Idunn’s best choices of Special, as they grant her an additional layer of sustain on top of her already incredible bulk. Noontime can trigger every combat with Special Fighter, but if more damage is desired or Bold Fighter is used, Aether may be preferable.
For Idunn’s A slot, Distant Counter is ideal as it allows her to counterattack ranged opponents. However, she can still work well with many Defensive A slot skills, such as her innate Sturdy Stance 3.
Pulse Smoke is Idunn’s best choice of C slot, as it allows her to circumvent otherwise Deadly enemy specials, such as Luna.
For Idunn’s Sacred Seal, both Mirror Stance and Quick Riposte work well, Mirror Stance working better with Noontime, and Quick Riposte working better with Aether.

Sacred Seal: Distant Guard / Chill Attack

Idunn can also function as a great support unit for Dragon and Armored allies thanks to her duo skill, which allows them to negate their biggest weakness for a turn. Keep in mind that Idunn’s duo skill cannot be used on AR Defense, however.
Idunn’s Zephyr Breath remains an amazing option due to how much it increases Idunn’s performance in combat. However, if nothing but raw durability is desired, a Defense forged Water Breath is also a decent option.
For Idunn’s A slot, Fort Def/Res increases Idunn’s visible bulk significantly, which also makes her an even better user of Sabotage skills.
Sabotage Skills allows Idunn to debuff one of the foe’s stats by 7 as long as her Resistance is 3 points higher than the foe’s. As Idunn’s resistance already rests at a high base value of 38 on top of having a superasset, she can make great use of these skills to support her team. Wary Fighter should be used with Water Breath so that she can retain follow-up Attack negation.
Support skills should be used in Idunn’s C and Sacred seal to provide her team additional support. In particular, Dragon Buffs and Distant Guard can make dragon supertanks much more potent when coupled with her duo skill.

Strengths

Duo Hero

Spring Idunn is inherently advantaged as a Duo, as her status as one grants her access to an incredibly powerful Duo skill, in addition to a Duel effect for scoring in modes such as Arena(Although Idunn benefits little from this due to her high Base stat total)

Zephyr Breath

Idunn’s Zephyr Breath is also an amazing prf, inflicting atk -6, neutralizing her stat penalties, and negating the foe’s follow-ups during combat, provided she is within 2 spaces of an ally, or a field buff is active on her.

Excellent Statline

In addition to these boons, Idunn’s statline is simply excellent. Her lowest stat is her middling 26 Speed, but due to the effect of her Zephyr breath, she’ll hardly notice it. Idunn not only hits hard with her base 37 Attack, but is also incredibly tanky due to her relatively high HP and great Defense and Resistance, and on top of this, both of her Defensive stats receive a 4 point increase instead of the usual 3 as an Asset.

Weaknesses

Effective Damage

While Idunn’s Duo skill allows her to circumvent this weakness to some extent, she’s still highly susceptible to effective damage when her Duo skill isn’t active due to her status as an Armored Dragon, leaving her weak to both Armored and Dragon effective damage.

Poor Mobility

As an Armored unit, Idunn’s base mobility is quite low, and as such she will struggle to move across the map without team support such as Armor March or a Guidance Flier.

Spring Idunn build by ⓐⓚⓘⓡⓐ 03-19

	Zephyr Breath	A	Distant Counter
	Swap	B	Special Fighter 3
	Aether	C	Threat. Atk/Res 3
S	Quick Riposte 3

Show Explanation/Analysis

Duo Idunn is an armor monstrocity on a whole new level. Just by having an ally within 2 spaces or active buff up she gets the standard Idunn effects and more. 6 attack penalty on the enemy during combat and follow-up negation are just making her harder to be obliterated.
Having her Duo Active skill also makes things easier for her since it provides +6 Def/Res and Armor and Dragon Effectiveness immunity for 1 turn to units on a 5x5 grid where she is in the middle. Its quite possible that she would be the reason why people will start using Duo buildings (Duo's Indulgence for Offense and Duo's Hindrance for Defense) on Aether Raids.

Reasons for the build I recommend.
Defense Asset: Having defense for an Asset is the best choice because she gets 4 more defense making her be at 41 defense on 0 merges which is the same amount of resistance she has on neutral.
Aether: Boosts the damage output Idunn can deal and provides her sustainability within the match. Compliments very well with her Special Fighter.
Distant Counter: General usage to cover ranged attackers. You really want to maximize the adaptive damage effects that dragon units have.
Special Fighter 3: Its a great skill to use on armor units that are general fast or have ways to double on an enemy.
Threathen Attack/Res 3: A skill that lets you get buffed and actively debuff enemies nearby. Goes very well with her weapon especially when she is not within 2 spaces of an ally. Alternatively Threathen Attack/Def 3 is fine also.
Quick Reposte 3 Seal: Her only way to double during enemy phase. Goes very well with her Special Fighter since it does not provide and follow-up guarantees.
Assist skill: Swap is generally the assist to go for armors. Resposition is fine and Pivot is decent when using armor units on autobattles.

Duo Skill

Grants Def/Res+6 and the following status to unit and allies within 5 rows 5 columns centered on unit for 1 turn: "Neutralizes 'effective against dragons' bonuses and 'effective against armored' bonuses."
