Passive A: Close Foil / Close Counter 

Passive B: Null Follow-Up / Special Spiral 

Passive C: Pulse Smoke / Joint Drive Spd 

Sacred Seal: Spd/Res Solo 

  • Fimbulvetr allows Brunnya to become an excellent supertank. The ubiquity of debuffs in Aether Raids allows her to gain +4 to all stats (along with debuff neutralization) almost constantly, which is excellent for increasing damage output, follow-up consistency, and survivability.
  • Fimbulvetr + Close Foil + Spd/Res Solo effectively grants Brunnya debuff neutralization, +9 Attack, +10 Speed, +8 Defense, and +13 Resistance. While Close Foil doesn’t allow Brunnya to counterattack against Dragons, they are exceedingly uncommon in Aether Raids Defense. Spd/Res Solo works great for a superunit given that they’ll likely be away from their allies (or within 2 spaces to receive benefits from support allies) and occupying a chokepoint.
  • Brunnya has 2 main Special + B slot combinations:
    • Noontime + Null Follow-Up allows Brunnya to activate Noontime on her follow-up attack. While this can be a waste since she’ll likely be 2HKOing with lots of overkill (or OHKOing outright), Null Follow-Up is an excellent B slot given how common Impact and follow-up nullifying skills are.
    • Sol + Special Spiral allows Brunnya to have Sol at either 1 or 0 cooldown after she activates it for the first time. Once she receives an attack, she’ll be able to heal with Sol on her counterattack assuming no Guard effect is active.
  • Pulse Smoke inflicts +1 Special cooldown on the target and enemies within 2 spaces after combat, shutting down common Infantry Pulse teams that rely on Specials to nuke whatever stands in their way. Joint Drive Spd is a solid alternative, however, granting +4 Speed to Brunnya and allies within 2 spaces during combat.

Weapon: Fimbulvetr

Special: Sol 

Passive A: Mirror Stance 3 / Atk/Res Solo (3 or 4) 

Passive B: Special Spiral / Null C-Disrupt 

Passive C: Pulse Smoke / Atk Smoke 

Sacred Seal: Spd/Res Solo / Mirror Stance 

  • Brunnya’s relatively high Attack and Resistance make her an excellent choice for a ranged tank. Fimbulvetr further augments her capabilities, granting +3 Resistance in addition to +4 to all stats and debuff neutralization if her HP is < 100% or she has a penalty.
  • This set aims to stacks Brunnya’s Attack and Resistance in order to ensure she can score OHKOs and survive as many magical attacks as possible. As such, both Mirror Stance 3 and Atk/Res Solo are excellent choices; while the former only functions on Enemy Phase, it also has a Guard effect, preventing enemies with very low-cooldown Specials from potentially activating them twice in one combat if they perform a follow-up attack. 
  • The combination of Special Spiral and Sol allows Brunnya to have Sol with 1 cooldown after she first activates it. When she receives an attack on Enemy Phase, she’ll be ready to activate it again on her counterattack. Thanks to Attack stacking via Fimbulvetr and Mirror Stance, there’s a good chance she’ll be able to OHKO; if not, then there’s also a good chance she’ll be able to perform a follow-up attack thanks to Fimbulvetr and Spd/Res Solo. Alternatively, Brunnya can use Null C-DIsrupt to prevent Firesweep Bow and Dazzling Staff units from getting free chip damage and/or debuffs, then moving around Brunnya after a refresh to infiltrate the backlines.
  • Both Pulse and Atk Smoke are great C slot options, with the former shutting down prevalent Infantry Pulse Aether Raids Defenses and the latter being more consistent and helping against non-Infantry Pulse teams.

Avenging Zephiel (Offensive)

Fimbulvetr A Fury (3 or 4)
Alternate: Atk/Spd Push 4
Positional Assist B Desperation 3
Alternate: Null Follow-Up 3
Alternate: Glimmer
C Joint Drive Spd
Alternate: Spd Smoke 3

+ATK or +SPD / -HP

SSwift Sparrow 2
Alternate: Brazen Atk/Spd 3

Show Explanation/Analysis

Weapon: Fimbulvetr

Assist: Positional Assist 

Special: Iceberg / Glimmer 

Passive A: Fury (3 or 4) / Atk/Spd Push 4 / Swift Sparrow (2 or 3) 

Passive B: Desperation / Null Follow-Up 

Passive C: Joint Drive Spd / Spd Smoke / Flexible 

Sacred Seal: Swift Sparrow / Brazen Atk/Spd 

  • Although her 35/31 offenses are less than stellar, Brunnya can still use a fairly effective offensive set thanks to Fimbulvetr, as it neutralizes penalties and grants +4 to all stats if her HP is < 100% or she has a penalty. This effectively makes her offenses 39/35 and immune to visible debuffs, which looks much better.
  • This set is straight-forward in that its main focus is to increase offenses to ensure Brunnya can deal high amounts of damage and perform follow-up attacks as frequently as possible. Fury and Atk/Spd Push 4 are top A slot choices because their recoil damage allows Brunnya to always have Fimbulvetr’s +4 to all stats active, although Swift Sparrow works fine. As for the Sacred Seal, Swift Sparrow is preferred for consistency’s sake, but Brazen Atk/Spd’s HP condition synergizes well with Fimbulvetr’s. Joint Drive Spd grants +4 Speed to Brunnya and allies within 2 spaces during combat, but Spd Smoke’s -7 Speed infliction on enemies within 2 spaces of the target may be more appealing, especially if utilizing refreshers.
  • Desperation also synergizes well with Fimbulvetr, Fury or Atk/Spd Push’s recoil damage, and Brazen Atk/Spd, as it allows Brunnya to perform her follow-up attack before the enemy counterattacks if her HP is ≤ 75%. However, Null Follow-Up may be preferred to neutralize effects that guarantee the enemy’s follow-up attack or prevent Brunnya’s follow-up attack.



Brunnya’s personal weapon, Fimbulvetr, allows her to shine amidst her Blue Tome peers.

  • Although minor, Fimbulvetr grants +3 Resistance, which helps avoid Sabotage skills, tank magical attacks, and deal additional damage with Specials such as Iceberg and Glacies.
  • More importantly, if Brunnya’s HP is < 100% or she is inflicted with a penalty, then her penalties are neutralized and she receives +4 Atk/Spd/Def/Res during combat.

This allows Brunnya to become an excellent Player and/or Enemy Phase unit. Penalty neutralization is very significant in Aether Raids, where penalties from Bright Shrines, Dark Shrines, and Chill skills are very prevalent.

Infantry advantages

As an Infantry unit, Brunnya has access to several great skills, including Special Spiral, Null Follow-Up, and Null C-Disrupt.


Fimbulvetr, status as an Infantry unit, and access to alternative Blue Tomes such as Tannenbit, Flora Guide, and Spooky Censer allow Brunnya to be a very flexible unit capable of fulfilling multiple roles, even at once.

Free-to-play benefits

As a Tempest Trials+ unit, all players had the opportunity to receive 1 4-star copy and 1 5-star copy of Brunnya. In addition, Brunnya can be obtained via Heroic Grails rather than Orbs, which is a blessing for many players.

While F2P units formerly lacked access to IVs, with the addition of Trait Fruit, players can feed their units 100 Trait Fruit to change their IVs however they’d like.


Overall middling statline

While none of Brunnya’s stats are outright bad with the exception of Defense, they also fail to stand out on paper. 42 HP, 35 Attack, and 33 Resistance are all decent, but not notably high, and 31 Speed is very middling for today’s standards. Thankfully, Fimbulvetr significantly helps with patching her statline, as +4 to all stats and debuff neutralization can make Brunnya deceptively strong, fast, and bulky.

Free-to-play drawbacks

If players missed Brunnya’s Tempest Trials+ event, then they will need to use Heroic Grails to begin to build Brunnya as opposed to potentially having a +1 Brunnya before spending. In addition, players that are already investing into another unit that needs to be merged via Heroic Grails may find it more difficult to justify building Brunnya.
