Heiðrún Skills at 5★

Nectar Horn Might: 14　 Range: 1 Accelerates Special trigger (cooldown count-1). At start of player phase or enemy phase, if any foes within 3 rows or 3 columns centered on unit have Res less than unit's Res+5, inflicts Atk/Def-7, 【Discord】, 【Deep Wounds】, and a penalty that neutralizes non-Special "if foe would reduce unit's HP to 0, unit survives with 1 HP" effects on those foes through their next actions. If foe initiates combat or foe's HP ≥ 75% at start of combat, inflicts Atk/Def-6 on foe, inflicts penalty on foe's Atk/Def = 20% of unit's Res at start of combat, reduces damage from foe's attacks by 20% of unit's Res (excluding area-of-effect Specials), neutralizes foe's bonuses to Atk/Def (from skills like Fortify, Rally, etc.), and grants Special cooldown charge +1 to unit per attack during combat (only highest value applied; does not stack). At start of turn, if unit is adjacent to only beast or dragon allies or if unit is not adjacent to any ally, unit transforms (otherwise, unit reverts). If unit transforms, grants Atk+2, deals +7 damage when Special triggers, and neutralizes effects that grant "Special cooldown charge +X" to foe or inflict "Special cooldown charge -X" on unit.

Aegis Cooldown Count = 3 Reduces damage inflicted by attacks from foes 2 spaces away by 50%.

Stronghold Inflicts Atk-3. Grants Def/Res+7. At start of player phase or enemy phase, neutralizes 【Panic】 and any penalties to unit's Def/Res that take effect on unit at this time.

Atk/Def Bulwark 4 Foe's with Range = 1 cannot move through spaces adjacent to unit, and foes with Range = 2 cannot move through spaces within 2 spaces of unit (does not affect foes with Pass skills). Inflicts Atk/Def-4 on foe and reduces damage from foe's first attack by 40% during combat ("first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes). Restores 7 HP to unit after combat.

Divine Nectar At start of player phase or enemy phase, if unit is within 2 spaces of an ally, grants 【Divine Nectar】 to unit and allies within 2 spaces of unit for 1 turn. If a Rally or movement Assist skill (like Reposition, Shove, Pivot, etc.) is used by an ally with the 【Divine Nectar】 effect active (excluding unit), grants another action to that ally (once per turn; if another effect that grants action to unit has been activated at the same time, this effect is also considered to have been triggered). If unit is within 3 spaces of an ally, inflicts Atk/Def-5 on foe and inflicts Special cooldown charge -1 on foe per attack during combat (only highest value applied; does not stack). 【Divine Nectar】 Restores 20 HP to unit as unit's combat begins (triggers after effects that deal damage as combat begins; only highest value applied; does not stack). If it is unit's first combat initiated by foe or first combat initiated by unit that turn, reduces damage from foe's attacks by 10 during combat (excluding area-of-effect Specials).

Heiðrún Best IVs

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (18)		★★★☆☆
Atk (15)		★★★★★
Spd (3)		★☆☆☆☆
Def (12)		★★★★★
Res (8)		★★★★★

◯ = 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

The best IVs for Heiðrún are +Res and -Spd. Res is Heiðrún's most important stat used in Nectar Horn's Res checks, and enhancing it improves her performance overall, both offensively and defensively.

Spd is a clear dump stat at only base 16 and is a safe bane to take.

+Res for a +10 merge

We recommend +Res when merging Heiðrún up to +10 to maximize Nectar Horn effects both in and out of battle.

Heiðrún Roles, Strengths, and Weaknesses

Heiðrún Roles

Heiðrún - Healing Nectar 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

Heiðrún is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent to her Atk minus the foe's Def stat.

Heiðrún Strengths

Nectar Horn inflicts multiple penalties on foes

Heiðrún's Nectar Horn inflicts Atk/Def-7, 【Discord】, 【Deep Wounds】, and a status that neutralizes non-Special Miracle effects on foes within 3 rows or 3 columns centered on Heiðrún at the start of each turn.

In combat, Nectar Horn inflicts Atk/Def-6 and an additional Atk/Def penalty on Heiðrún's foe equal to 20% of Heiðrún's Res, grants Heiðrún damage reduction equal to 20% of her Res, and grants Heiðrún bonus Special cooldown charges per attack.

Nectar Horn also has the standard Infantry Beast transformation condition and effects, which grant Heiðrún Atk+2, +7 damage whenever her Special triggers, and a Tempo effect.

Divine Nectar grants allies extra actions

Heiðrún's Divine Nectar is what makes her unique among other heroes in the game.

At the start of player phase or enemy phase, Heiðrún grants the 【Divine Nectar】 status to herself and allies within 2 spaces. Then, if an ally with the 【Divine Nectar】 status uses a Rally or movement Assist skill, Divine Nectar grants them an additional action.

This effect is similar to the Chrom variants that have similar Assist skills like To Change Fate! and A Fate Changed!. If the Chroms abused this effect to remain viable in the metagame for a very long time, we expect Heiðrún to do the same, especially when she can grant this effect to multiple allies passively.

Even though only one extra action can be granted per turn, this is still a very powerful effect that can easily set up Rally traps in Aether Raids and increase action economy in Summoner Duels.

The 【Divine Nectar】 status restores 20 HP to the affected unit as combat begins, keeping their HP high. This healing effect takes place after pre-combat damage effects from skills like Flared Sparrow and Occultist's Strike, making it a counter to these skills.

The 【Divine Nectar】 status also reduces damage from foe's attacks by 10 on the affected unit's first combat initiated by unit and the first combat initiated by foe during that turn. This helps keep the affected units alive, working well with the healing effect to ensure survival.

In combat, Divine Nectar inflicts Atk/Def-5 on Heiðrún's foe and slows down their Special cooldown charges per attack.

Heiðrún Weaknesses

Weak to Beast Effective Weapons

Heiðrún takes 1.5x damage from beast-effective weapons like Brave Eliwood's Nini's Ice Lance or Picnic Flora's Sæhrímnir, and one blow from this type of weapon will deal significant damage. Make sure you know what weapons you are up against before hopping too far into the line of battle!
