Heimdallr Skills at 5★


Might: 14  Range: 2
Accelerates Special trigger (cooldown count-1).
If defending in Aether Raids, at the start of enemy phase, grants 【Foresight Snare】 to allies closest to the bottom of the map within 3 columns centered on unit for 1 turn. If not defending in Aether Raids, at the start of enemy phase, if there is only one ally (excluding unit) with the highest Def among allies closest to foe, grants 【Foresight Snare】 to that ally for 1 turn.
For foes within 3 rows or 3 columns centered on unit, inflicts Atk/Def/Res-5 and neutralizes foe's bonuses to Atk/Def/Res during combat.
At start of combat, if unit's HP ≥ 25%, inflicts penalty on foe's Atk/Res = 20% of unit's Res at start of combat, unit deals +X damage (excluding area-of-effect Specials), and reduces damage from foe's attacks by X during combat (excluding area-of-effect Specials; X = number of allies within 3 rows or 3 columns centered on unit x 5; max 15), and restores 7 HP to unit after combat.
【Foresight Snare】
If foe initiates combat and there were no combat instances on the current turn yet (player phase and enemy phase are counted separately), triggers the following effects:
- Cancels foe's attack, ending their action.
- Inflicts 【Isolation】 and status preventing

- Cancels Foresight Snare granted to your army.
(These effect trigger after Aether Raids traps but before Savior; does not trigger in Pawns of Loki).

Cooldown Count = 4
Boosts damage by 70% of unit's Res when Special triggers.
If unit's or foe's Special is ready, or unit's or foe's Special triggered before or during this combat, and also, if unit's Res ≥ foe's Res-10, reduces damage from foe's next attack by 40% (once per combat; excluding area-of-effect Specials).

If unit initiates combat or is within 3 spaces of an ally, grants bonus to unit's Atk/Res = unit's maximum Special cooldown count + 7 during combat, and also, when unit's Special triggers, deals damage = unit's maximum Special cooldown count × X (excluding area-of-effect Specials; if unit triggers the "unit attacks twice" effect, X = 3; otherwise, X = 5).

Enables 【Canto (Rem.; Min 1)】.
At start of player phase or enemy phase, inflicts 【Exposure】, 【Discord】, and 【Stall】 on foes with Res < unit's Res and that are within 2 spaces of another foe through their next actions.
At start of combat, if unit's HP ≥ 25%, inflicts Atk/Res-5 on foe, foe cannot make a follow-up attack, inflicts Special cooldown charge -1 on foe per attack (only highest value applied; does not stack), deals damage = 20% of unit's Res (excluding area-of-effect Specials), reduces damage from foe's attacks by 20% of unit's Res (excluding area-of-effect Specials), and grants Special cooldown count-1 to unit before unit's first attack during combat.

At start of turn, if unit is within 2 spaces of an ally, grants Atk/Res+6 and "reduces the percentage of foe's non-Special 'reduce damage by X%' skills by 50% during combat (excluding area-of-effect Specials)" to unit and allies within 2 spaces of unit for 1 turn.
Grants bonus to unit's Atk/Res during combat = 2 + number of allies on the map with the "reduce damage by X%' skills by 50% during combat (excluding area-of-effect Specials)" status effect active, excluding unit (max 5).

Heimdallr Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (18) Normal HP ★★★☆☆
Atk (14) No Attack IV ★★★★★
Spd (3) Spd Bane ★☆☆☆☆
Def (5) No Def IV ★★☆☆☆
Res (10) 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.

+Res / -Spd

The best IVs for Heimdallr are +Res and -Spd. Res is the key stat for the stat checks of both Mystic Gjallarhorn and An Open Book, making it Heimdallr's most important stat. It should be boosted as much as possible in order to maximize Heimdallr's effectiveness.

Spd is Heimdallr's worst stat and can be safely taken as a bane as it won't impact any of her matchups.

+Res for a +10 Merge

We recommend a +Res IV when merging Heimdallr up to +10 for similar reasons above.

How to Use, Explanation

Heimdallr's base kit is already good enough to function as a magic tank and support hybrid. She is a great wielder of Emblem Corrin ring to maximize role compression and further protect her team with its terrain effects, especially the Foresight Snare recipient.

Heimdallr is a ranged magic attacker (range = 2). 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.

Heimdallr Strengths

Mystic Gjallarhorn Grants 【Foresight Snare】 to an Ally

Heimdallr's exclusive weapon Mystic Gjallarhorn grants 【Foresight Snare】 the bottom-most unit within 3 columns of Heimdallr if fielded on Aether Raids Defense, or to the ally with the highest Def closest to an enemy if playing other game modes.

【Foresight Snare】 is a new status effect that triggers the following effects if an enemy unit initiates combat into the unit with 【Foresight Snare】, and if that combat is the first combat on the current phase:

  • Cancels foe's attack, ending their action.
  • Inflicts 【Isolation】 and 【Flash】 on foe through foe's next action.
  • Cancels 【Foresight Snare】 granted to your army.

【Foresight Snare】's effects are devastating if it triggers, instantly ending the foe's action and inflicting 【Isolation】 and 【Flash】 onto the initiating foe.

Mystic Gjallarhorn also inflicts Atk/Def/Res-5 and neutralizes foe's bonuses to Atk/Def/Res for all foes within 3 rows and 3 columns centered on Heimdallr, giving her team additional support on top of 【Foresight Snare】.

In combat, Mystic Gjallarhorn inflicts an Atk/Res penalty onto Heimdallr's foe equal to 20% of her Res and grants her up to +15 bonus true damage and true damage reduction based on the number of allies within 3 rows and 3 columns, and grants Heimdallr 7 HP post-combat healing.

Mystic Gjallarhorn is a great support weapon if set up correctly and 【Foresight Snare】 is maximized, while retaining good combat potential.

For best results, set up your team so that the unit granted 【Foresight Snare】 has a Bulwark and/or an anti-Warp effect from skills like Barricade, preventing foes from advancing past him/her and forcing them to attack into him/her first.

An Open Book inflicts Exposure, Discord, and Stall

Heimdallr's exclusive B skill An Open Book enables 【Canto (Rem.; Min 1)】 and inflicts 【Exposure】, 【Discord】, and 【Stall】 on foes with less Res than Heimdallr and are within 2 spaces of any other foe.

This effect is very powerful, as multiple metagame units have effects that grant them Movement +1. Applying 【Stall】 to a group of enemies at the start of each phase counters this and heavily impacts teams built on mobility.

In combat, An Open Book inflicts Atk/Res-5 and a Guard effect onto Heimdallr's foe, denies their follow-up attack, grants Heimdallr bonus true damage and true damage reduction equal to 20% of her Res, and 7 HP post-combat healing.

An Open Book's main use is for its widespread penalties, making Heimdallr a powerful support unit to field in battle. The in-combat effects are relevant as well, helping Heimdallr hold her own in battle.

Heimdallr Weaknesses

【Foresight Snare】 is Easily Avoided

【Foresight Snare】 can be easily avoided by attacking a different unit without 【Foresight Snare】 first in order to avoid its devastating effects.

【Foresight Snare】 only triggers if there were no combat instances on the current phase yet, rendering it useless if the affected unit isn't involved in the first combat of the current phase. Since 【Foresight Snare】's effects trigger before Savior, it is safe to attack the other units first.

Low Spd and Def

Heimdallr's Spd and Def stats are quite low, leaving her vulnerable to fast physical attackers that have built-in Null Follow-Up effects.

Initiate into Heimdallr with a fast physical attacker to defeat her in one round of combat!

Weak to Cavalry Effective Weapons

Heimdallr takes 1.5x damage from cavalry-effective weapons like Thani or Binding Reginleif, 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!

that was supposed to say, "for foresight snare, & so she can't be taken out asap."

1 twztid13 twztid13 30 days

The problem with giving her the Corrin emblem is that she needs to be on the back row for so she can't be taken out asap (I'm assuming she doesn't give it to herself, but haven't tested that). The Corrin emblem is best on someone on the front row,,so the canto control has max range. 🤔
