Might: 14 Range: 1 Accelerates Special trigger (cooldown count-1). Foes with Range = 1 cannot warp into spaces within 3 spaces of unit, and foes with Range = 2 cannot warp into spaces within 4 spaces of unit (in either case, does not affect foes with Pass skills or warp effects from structures, like camps and fortresses in Rival Domains). At start of player phase or enemy phase, if unit is within 2 spaces of an ally, grants Atk/Def+6, 【Fringe Bonus】, "neutralizes foe's bonuses during combat," and【Null Panic】to unit and allies within 2 spaces of unit for 1 turn. If unit is within 2 spaces of an ally, and if unit or allies within 2 spaces of unit have bonuses to Atk/Spd/Def/Res after start-of-turn skills trigger, or, if defending in Aether Raids, after start-of-turn skills trigger at the start of turn 1 of enemy phase, grants an additional +3 to each corresponding stat for unit and those allies for 1 turn (calculates each stat bonus independently; max 10). If unit is within 3 spaces of an ally, grants bonus to unit's Atk/Def/Res = 20% of unit's Def at start of combat + 5, unit deals +X damage (excluding area-of-effect Specials), reduces damage from foe's attacks by 50% of X during combat (excluding area-of-effect Specials), and reduces damage from foe's Specials by an additional 50% of X during combat (excluding area-of-effect Specials; X = highest total bonuses among unit and allies within 3 spaces of unit). 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, and unit can counterattack regardless of foe's range. |
|
Range: 1 Unit and target ally swap spaces. If unit uses an Assist skill on the current turn, enables 【Canto (1)】. |
|
Cooldown Count = 3 Boosts damage by 60% of unit's Def when Special triggers. At start of player phase or enemy phase, grants Res+6 and 【Magic Twin Save】 to target allies within 2 spaces of unit for 1 turn (if support partner is on player team, targets any support partner; otherwise, targets ally with the highest Res at start of battle, excluding unit; "at start of battle" excludes increases to Res granted after ally is deployed, such as Legendary Effects, Mythic Effects, Bonus Heroes, Great Talent, etc.; does not trigger when unit is equipped with "Savior" effects other than 【P Save】). Reduces damage from foe's attacks during combat by 40% (excluding area-of-effect Specials) and grants Special cooldown count-X ÷ 12 (rounded down) to unit before unit's first attack during combat (X = highest total bonuses among unit and allies within 3 spaces of unit), and also, if unit's Def ≥ foe's Def+5, disables unit's and foe's effects that change attack priority during combat. |
|
If unit can transform, transformation effects gain "if unit is within 2 spaces of a beast or dragon ally, or if number of adjacent allies other than beast or dragon allies ≤ 2" as a trigger condition (in addition to existing conditions). If defending in Aether Raids, at the start of enemy turn 1, if conditions for transforming are met, unit transforms. If unit is transformed or if foe initiates combat, grants Atk/Def+8 to unit and neutralizes foe's bonuses to Atk/Def during combat, and restores 7 HP to unit after combat. |
|
If unit initiates combat or is within 3 spaces of an ally, inflicts Atk/Def-4 on foe, deals damage = 20% of unit's Def (excluding area-of-effect Specials), reduces damage from foe's attacks by 20% of unit's Def (excluding area-of-effect Specials), unit makes a guaranteed follow-up attack, and reduces the percentage of foe's non-Special "reduce damage by X%" skills by 50% during combat (excluding area-of-effect Specials). |
|
If sword, lance, axe, bow, dagger, or beast foe initiates combat against an ally within 2 spaces of unit, triggers 【Savior】 on unit. If foe uses sword, lance, axe, bow, dagger, or beast damage, grants Atk/Def+4 to unit, disables foe's effects that "calculate damage using the lower of foe's Def or Res" (including area-of-effect Specials), and reduces damage from foe's first attack by 5 during combat ("first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes), and unit's next attack deals damage = 40% of foe's attack damage prior to reductions (resets at end of combat; only highest value applied; does not stack). |

| 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.
The best IVs for Brave Eikþyrnir are +Def and -Spd. As a dedicated physical tank, Eikþyrnir relies on his Def to perform his role, and it even helps with his damage output through Tempered Antler's bonus stats and Mighty Roar's bonus damage.
Spd is a clear dump stat and can be safely taken as a bane.
We recommend +Def when merging Brave Eikþyrnir up to +10 for similar reasons above.

Brave Eikþyrnir already comes with a great base kit to have him excel as a tank unit. With his built-in Hardy Bearing effect, his Sacred Seal is now free, simply equip the defensive Seal of your choice.

| Eikþyrnir - Resolved to Train Roles | |||
|---|---|---|---|
Harmonized |
|||
Brave Eikþyrnir is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage he deals will be equivalent to his Atk minus the foe's Def stat.

Brave Eikþyrnir's exclusive weapon Tempered Antler has Barricade built-in and grants Atk/Def+6, 【Fringe Bonus】, neutralizes foe's bonuses during combat,
and【Null Panic】 to himself and allies within 2 spaces at the start of both player and enemy phase.
【Fringe Bonus】 is an updated 【Bonus Doubler】 effect that also checks for the highest bonus among allies within 2 spaces in addition to the unit.
More importantly, because it is an entirely new effect, it stacks with 【Bonus Doubler】 and 【Fire Emblem】, allowing players to stack all three of these Bonus Doubler statuses to create high stat gains!
Tempered Antler also has the bonus increasing effect all Eikþyrnir versions have, granting an additional +3 to each stat that has a visible bonus applied.
In combat, Tempered Antler grants Brave Eikþyrnir bonus Atk/Def/Res equal to 5 + 20% of his Def, bonus true damage, true damage reduction, and true damage reduction on specials equal to the highest total bonuses among himself and allies within 3 spaces.
Tempered Antler also has the standard Armored Beast transformation effects, granting him Atk+2 and Distant Counter.
Tempered Antler is a good weapon for defensive units, providing support to allies while also having all the effects modern weapons have such as bonus stats, true damage, and true damage reduction.
List of Status Effects: Bonuses and Penalties
Brave Eikþyrnir's exclusive Special Mighty Roar boosts his damage by 60% of his Def when it triggers grants Res+6 and 【Magic Twin Save】 to either his support partner (if present) or to his ally with the highest Res at the start of player and enemy phase.
【Magic Twin Save】 is a new status effect that neutralizes adaptive damage and allows the affected ally to trigger Savior against breath, tome, and staff foes. Paired with his base kit's A/D Briar P Save, Brave Eikþyrnir alone can set up a Savior effect that covers all areas.
In combat, Mighty Roar grants Brave Eikþyrnir 40% damage reduction and a Special jumping effect (which will almost always pre-charge Mighty Roar), and triggers a Def check which grants him a Hardy Bearing effect if he wins the check.
With Brave Eikþyrnir sky high Def stat and various boosts, he will almost always win this Def check, which makes the Hardy Bearing a reliable effect to trigger in every combat.
Brave Eikþyrnir is a powerful unit, but he can only cover his allies from physical damage.
He will need a dedicated partner to cover for magic damage with his 【Magic Twin Save】 effect, which may restrict teambuilding.
Brave Eikþyrnir 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!
Brave Eikþyrnir takes 1.5x damage from armor-effective weapons like Randgríðr, 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!
