IV Sets

Key stats worth increasing through nature if possible.
Complementary stats that matter, but not to the point of picking them over key stats for nature increase.
Relatively worthless stat that can safely be decreased through nature.


  • +SPD: An Asset here brings Nowi's average 32 Speed to a much more workable 35, giving her better chances of performing follow-up attacks as well as avoiding those from enemy units. Consequently, Nowi can take better advantage of flier-specific offensive buffs including Goad Fliers and Hone Fliers.
  • +ATK: Bettering Nowi's base 34 Attack via an Asset improves her single-hit damage output, which is a good prospect for variants of builds that aim to one-shot or simply can't afford to focus on Speed.


  • RES: At base 27, Nowi's Resistance isn't particularly impressive but is her highest defensive stat of the two. It should be kept neutral, but it is acceptable if Nowi must take it as a Flaw (untouched physical bulk for Rauðrraven builds) or an Asset (potential Resistance stacking with Atk/Res Bond).
  • HP: Nowi starts with a worrying base 34 HP, and taking it as a Flaw even further debilitates her overall survivability. It doesn't particularly benefit her as an Asset either when Attack and Speed are far better, making it better left at neutral when possible. It is acceptable on some builds, with respect those that wish to get to Desperation range quicker. 


  • -DEF: Defense is the safest Flaw to take as Nowi's physical durability is already very low at zero merges.

Show Explanation/Analysis

Preferred IV: +SPD or +ATK / -DEF or -HP

  • A Speed asset is recommended when using Desperation and simply increasing Nowi's chances of performing follow-up attacks. Attack is overall better for single-shot damage, helped even further by Rauðrblade's high damage ceiling.

  • Defense is valued as a flaw it least likely affects this build's relevant matchups. HP is acceptable especially if using Fury 4, which allows Nowi to get into Desperation range after one round of battle if she has 32 HP at most.

Weapon: Rauðrblade+ 

  • Rauðrblade is Nowi's best chance at reaching high damage potential as it calculates additional Might based on the current number of visible bonuses on her. Considering Nowi's movement class and consequential access to bonus buffing skills such as Hone Fliers and Tactics, Rauðrblade is not difficult to use on her at all. 

Assist: Reposition / Flexible

  • Reposition is packaged by default and nothing else typically works better than that on Nowi, allowing her to distance herself and her teammates from enemy range by one space. Depending on your team and playing preferences, however, it can be easily replaced.

Special: Glimmer / Moonbow

  • Rauðrblade having a high damage ceiling along with an unfortunate cooldown delay of +1 makes Glimmer a perfectly good choice. Said Special relies on the amount of damage done to an enemy in the first place, and its short cooldown makes its activation reasonably frequent. 

  • Moonbow sports the same cooldown as Glimmer but instead takes the enemy's lowered Resistance into account. Thus, Nowi can at least deal some reliable burst damage in the event she is not properly buffed.  

Passive A: Fury (3 or 4) / Death Blow (3 or 4) / Swift Sparrow (2 or 3) / Mirror Impact

  • Fury and Swift Sparrow are optimal for builds with moderate to high Speed investment. The former's other advantages stem in direct stat padding in all other stats—which often translates to better survivability—whereas Swift Sparrow offers a higher accompanying Attack boost.

  • Death Blow 3 is a perfectly good and cheap choice for one-shot variants of this build. Its fourth tier variant offers the highest non-Brazen boost of all A-slot skills.

  • Mirror Impact is an option if this is being inherited along with Atk/Res Oath from legendary Julia. It does the usual job at increasing Nowi's damage while making initiations significantly safer thanks to the humongous +10 Resistance boost as well as disabling the opponent's follow-up attack.

Passive B: Desperation / Chill Res / Wings of Mercy / Flier Formation / Flexible

  • Desperation should be the B-slot of choice on Speed-superinvested builds, allowing Nowi to perform any follow-up attacks immediately after her first hit once below 75% HP. This aids in Nowi's survivability as she is less susceptible to mortal counterattacks in player phase.

  • For slower builds, Nowi has quite a few viable choices on the menu. Chill Res, for example, provides passive team support while augmenting Nowi's own damage output on applied targets. Wings of Mercy gives Nowi some potent movement options when her teammates are badly damaged, whereas Flier Formation also provides improved mobility in flier-only setups.

  • One-shot builds have a ton of unmentioned options, including Links, other Chills, and flier movement skills, that are considerable depending on the team context and personal preferences.

Passive C: Hone Fliers / Atk/Res Oath / Goad Fliers / Flexible

  • Nowi's base Hone Fliers is great as-is, offering nice dual offensive bonuses to flier allies adjacent to her at the start of the turn. It should be noted that this might lead to support redundancy issues as Nowi is using a bonus-reliant weapon herself and cannot benefit from her own Hone. Thus, Goad Fliers is a great, stackable alternative that benefits teammates at a distance. 

  • Atk/Res Oath is listed for the sake of optimization; it rewards a bonus of 5 to both of its namesake stats if Nowi is adjacent to an ally at the start of the turn. This effectively adds 15 extra Might to Rauðrblade and completes half of the stat array. 

  • Otherwise, the C slot is open depending on your team needs and personal preferences. 

Sacred Seal: Chill Spd / Brazen Atk/Spd / Sturdy Blow / Darting Blow / Flexible

  • Chill Spd acts as a solid support skill, allowing Nowi to passively lower the Speed of an opposing superunit by a harsh -7. This serves to help Nowi secure follow-up attacks on enemies she couldn't do so before, as well as fortify teammate performance when Nowi herself isn't doing much.

  • Brazen Atk/Spd offers the largest possible selfish Atk/Spd boost from a Sacred Seal; however, its HP threshold requires Nowi to survive a round of damage or use a specific setup (such as using Fallen Berkut's Kriemhild).

  • Sturdy Blow requires no setup to benefit from its immediate Attack boost on initiation, and the Defense boost comes in handy sometimes for safer matchups against physical units that hit at range.

  • Darting Blow offers an immediate Speed boost on initiation, greatly increasing the rate of follow-up attacks and synergizing with Desperation.

  • The Sacred Seal slot is open to any other choices at your disposal depending on what has already been forged/taken and what Nowi's teammates prefer.

Reposition B Axebreaker 3
Alternate: Swordbreaker 3
Alternate: Luna
C Hone Fliers
IVsSIote's Shield
Alternate: Atk/Res Bond 3

Show Explanation/Analysis

Preferred IV: +SPD or +ATK / -RES

  • This build is designed to make the most of any copy of Halloween Nowi usable for specific matchups, meaning the Assets and Flaws are actually quite flexible here. Even an Attack or Speed Flaw isn't too lame in the scheme of things.

  • For Rauðrraven + Triangle Adept builds in particular, keeping Nowi's Defense and HP intact allows her to maintain good matchups against opposing bow and dagger enemies. Magical green attacks are usually meanwhile covered by Nowi's decent Resistance and Triangle Adept.

Weapon: Grimoire / Rauðrraven+

  • Grimoire is good as-is for those unwilling to spend 20,000 feathers for Rauðrraven yet or ever. At the very least, it offers both decent Might and maneuverability options above 50% HP. 

  • Rauðrraven can be used in conjunction with Triangle Adept to specialize Nowi against colorless targets, minimizing their damage while granting the typing advantage in Nowi's attacks. This combination also allows Nowi to acts as a dedicated bow unit check for flier teams.

Assist: Reposition

  • Reposition already comes equipped on Nowi and there's little need to replace it as it does a fine job at helping Nowi and her teammates away from enemy range.

Special: Moonbow / Luna

  • This build is not particularly splendid in the damage department, meaning the only real options for this build are Moonbow and Luna. Both deal short-timed, usually good burst damage as they treat the opponent's Resistance as if lowered.

Passive A: Triangle Adept / Atk/Res Bond

  • Triangle Adept is an easily accessible and handy option that magnifies triangle advantage against green foes, as well as colorless ones if using Rauðrraven. This allows Nowi to tank attacks from these targets and strike back effectively with near-minimal damages. Against Legendary Alm, Legault with Red-Hot Ducks, and other colorless units with access to true damage, however, Nowi should not invest full faithfulness in this combination especially considering her otherwise average bulk.

  • Atk/Res Bond comes by default and improves Nowi's damage output as well as magical resilience. With Grimoire improving Nowi's mobility and encouraging her to be adjacent to allies, she has many opportunities to make use of the boosts. 

Passive B: Axebreaker / Swordbreaker / G Tomebreaker / Daggerbreaker 

  • A weaponbreaker of choice allows Nowi to more quickly close matches against desired targets and generally overcome her average, uninvested Speed against such threats. 

  • Axebreaker spells certain doom to most bulky axe units who already suffer from Nowi's red magic hits. In particular, if Nowi wins the natural Speed advantage (i.e. 5 more effective Speed), she can overcome Wary Fighter and bring down the likes of Surtr, Legendary Hector, and Brave Ephraim in one round.

  • Swordbreaker evens out matchups against fast sword units who are otherwise often able to tank a single hit from Nowi. This also protects Nowi from potential ORKOes if she absolutely must tank assaults from usually deadly units such as Karla and Legendary Roy.

  • G Tomebreaker acts similarly to Axebreaker in that it ensures more comfortable fights against green foes. In particular, deadly tome users such as Nino, Brave Micaiah, and Lewyn can have close matchups turn completely hopelessly for them.

  • Daggerbreaker similarly turns the tables on most colorless dagger units if your team has a particular distaste towards certain ones. 

Passive C: Hone Fliers / Flexible

  • To make up for Nowi's lack of general offensive presence outside of specific matchups, her default C-slot skill Hone Fliers is a perfectly good offensive support skill for fellow fliers. Her C slot should be outfitted to her team and personal preferences otherwise.

Sacred Seal: Iote's Shield / Atk/Res Bond / Other Bond skills / Flexible

  • Iote's Shield further protects Rauðrraven builds from further damage by completely neutralizing effective damage from bows and Excalibur. 

  • Atk/Res Bond can be doubly run with itself in A slot form to further help out Nowi in their namesake stats, which helps her tank a wider variety of magic attacks while pushing her damage output further. Other Bond skills are up for consideration as well depending on which stats you would like to improve.

  • If another unit is busy using these seals or Nowi isn't using Rauðrraven at all, the Sacred Seal slot is perfectly open to a variety of other available options such as other Bond skills.


Nowi steps back from her traditional role as an enemy phase dragon tank and reclasses to a Witch for the Harvest Festival, giving her a remarkably different list of tricks-to-treat compared to her old self. At the time of her release, Halloween Nowi was one of the first of her kind in relation to her movement class: a flying red mage with a unique weapon and Hone Fliers (rare at its time) was nothing short of impressive. With an offensive statline that was considered respectable at the time, Nowi provided a witchy amount of zest to flier teams and the game in general. The only factors effectively stopping her from reaching true chocolate-covered trickery was her seasonal exclusivity and defensive frailty (which is normal for most conventional mages anyway). 

Now that much time has passed since then, however, Nowi's tricks have lost much of their treat. While Nowi's perks as an offensive flier mage are still widely respected and contribute much to her normally physically-inclined movement class, much has been added to the game that makes her as green as her potions. It is particularly difficult to sell Nowi as a unit overall compared to her most comparable competitor Aversa, who basks in the benefits of her free availability,  mostly better Aversa's Night, and slightly better-optimized statline. Nowi's prescribed role as a Bonds stacking user is also mostly overshadowed by Adrift Camilla, whose Book of Dreams directly benefits herself in-combat when adjacent to allies. This speaks nothing of a number of new threats that Nowi may be hard-pressed to face directly, including Legendary Julia and Idunn.

Halloween Nowi is thus nowadays better suited to running a Rauðrblade build to maximize her offensive presence, or running type-check builds to account for specific threats in Arena Assault. Though tough competition can suck quite harder than the lollipops in her Special art, the Eternal Witch carries herself together with access to Flier perks in conjunction with increased attack range, a malleable offensive statline, and her unique, spicy brand of Halloween cheer.


Decent Offensive Stats

With 34 base Attack, Nowi will rarely fail to do at least some damage to most relevant targets. While 32 Speed isn't exactly helping Nowi snatch her candy faster, it's perfectly improvable with some tricks, especially in the form of certain A slot skills, Sacred Seals, and outsourced team support options like Goad Fliers and Chill Spd.

Flier Perks 

As a flying unit herself, Nowi benefits from a variety of advantages offered by her flying class. Firstly, she has standard two-space movement and is able to traverse otherwise difficult terrain such as mountains and bodies of water. Such movement is improved with a library of mobility skills like Air Orders and Flier Formation. Finally, for direct battle performance, Nowi is also able to make the most out of exclusive skills including Mirror Impact, Goad Fliers, Hone Fliers, Atk/Res Oath, and much more.


Bog-Standard Defenses

Frailty and a bow weaknesses are expected and nonetheless disappointing of Nowi's archetype. With only 34 base HP barely held up by mere defensive values of 20 Defense and 27 Resistance, a majority of units can badly damage Nowi or even one-round her if left wide-open. Even with specific skills promoting her tankability, there is only so much punishment the Eternal Witch can take. 

Limited Accessibility

Halloween Nowi is available only once per year in the Trick or Defeat! summoning focus event, with no other dedicated banners featuring her in the foreseeable future. She is thus susceptible to powercreep, not to mention somewhat of an extraneous luxury especially considering certain direct competitors are available at other times or simply year-round. 

Difficult Competition 

It's not just overeating the candy that's making Nowi green, as recently-added red mage entries in the game somewhat humble her place in the game. Her most blatant and direct competition, Aversa, is free to summon from Heroic Grails anytime and features a number of notable advantages, including higher Speed, more overall bulk, and a unique support weapon that translates well in both Colosseum and Aether Raids environments. Other currently-released units such as Soiree Ishtar and Adrift Camilla also make Nowi a relatively difficult sell.
