|This build aims to build Nowi into a flexible, tanky counter to Emblem Buff teams that can also stand up to non-buff teams. This build utilizes Quick Riposte as the B skill, allowing you to give her extra defense using her Sacred Seal slot.
There are two ways to implement this build. Either you can simply build her as a standalone unit, or use her as a central piece of your team. Depending on which path you decide to go will determine your IV, and Weapon Refinement.
For a standalone unit, you will want to double down on defense with +Def boon and +Def refinement for Lightning Breath+. This allows her to tank the vast majority of Red units, all variants of bow units, and a large number of lances, and even axes. Steady Breath, along with Bonfire, allows Nowi to one shot brave weapon users in addition to fighting against other units that are otherwise tanky.
If one desires to fully invest into Nowi, including Summoner Support, Ally Support and buffs, +Spd boon and +Spd refinement can get a lot of mileage, as it allows Nowi to escape doubles from many units that would otherwise double her.
Lightning Breath+, Nowi's native weapon, is her weapon of choice. Having built in Distant Counter in addition to being refined to hit the weaker defense stat of ranged units allows her flexibility in terms of the threats she can handle.
Reposition is a standard, powerful movement tool that allows tanks to move units behind them, and then acting as a wall for them on the enemy phase, or just generally moving units around. Though, this can be changed depending on the team composition.
Bonfire is the staple choice for her special, as you want a 3 cooldown special ability, increased to 4 from her weapon to fully utilize this build. Alternately, a 5 Cooldown special in Aether can be used to allow for sustain if going the full speed build, as she will usually be able to one round enemies in two hits, and then you'll have Aether ready for the next turn.
Steady Breath allows Nowi to utilize both of her special options in a timely manner. The usual detriment of +1 Special Cooldown of Lightning Breath+ becomes a mitigated, as Bonfire will have a Cooldown of 4, allowing Nowi to use it on the 4th combat action (such as get hit, hit back, use bonfire on the second hit). Aether will have a cooldown of 6, allowing her to use it on her 4th combat action, usually right after the first kill as a player phase action or secondary enemy phase action.
Quick Riposte 3 is an essential skill, to have, especially when not used in her Sacred Seal. Because Nowi will never have enough speed to naturally double an enemy, Quick Riposte ensures that Nowi will be able to always double enemies on the Enemy Phase. This then allows her to either use Bonfire or have Aether ready afterwards.
Panic Ploy 3 is the overall most useful C skill, as even with the -HP IV she will still be able to panic all mages and most non-armored units due to having +5 HP from the ightning Breath+ refinement. This can shut down Horse, Flier, and Mage Armor Emblem teams, allowing for easy baiting of enemies that have their buffs turned into penalties. It can also be switched to another C skill such as a Hone, Spur, Smoke, or Tactic depending on team composition and matchups you run into.
Distant Def 3 is the best Sacred Seal in terms of allowing Nowi to counter ranged threats such as Lyn, Brave Lady and blue mages. Alternatives include using Panic Ploy 3 if one doesn't run the C skill, and Close Def 3 allows Nowi to better combat tanky blue and green melee units.
Overall, using this build turns Nowi into a mostly Enemy Phase unit, utilizing her impressive bulk in order to bait enemies in and easily deal with them. However, against users of Sweep weapons such as Firesweep Bow, Lance, or Dazzling Staff, she can still player phase to hit them hard and be bulky enough to deal with the Sweep user's allies.
