|Nina's can use her high speed for an archer to naturally perform a follow-up attack even after the -5 speed from Brave Bow, allowing her to attack 4 times in one round of combat. This build performs similarly to Setsuna, but due to Nina's higher Res, she can effectively run Iceberg and Ploys in order to increase her damage, while her higher Atk gives her good damage even without merges. Quad Nina is most effective when paired with 3 Wings of Mercy dancers to solo the toughest of PvE maps, such as Abyssal Legendary Hero Battles.
+Atk or +Spd increases Nina's damage output, while -Def is an ideal bane due to Nina's already terrible physical bulk. -HP also works, but try to avoid -Res as Nina has the Res to use Iceberg and Ploys. A 3 charge special, such as Iceberg or Luna is preferred, as Nina's first 3 attacks will charge it ready for it to be fired on the 4th. Iceberg offers consistent damage based of Nina's high Res but Luna can help punch through the bulkiest of physical walls. Draw Back is a good positional assist that lets Nina aid allies without placing herself in danger on the Enemy Phase, but if run with Dancers, Reposition is ideal in order to keep Nina in front ready to attack for the next turn.
Fury gives Nina a good offensive boost, and is chosen over other options like Swift Sparrow and Life and Death in order to increase her visible Res, helping her land ploys and powering up her Iceberg. It also lets her safely enter Desperation range in order to fire off 4 hits before retaliation, which can be crucial against DC melees and dragons. The Brazen Atk/Res seal synergises well with the Fury + Desperation combo, increasing her damage by 31 each quad if she gets her special off, while also helping her tank enemy mages- with a +6 Res buff and drives, Nina can occasionally tank an Abyssal mage or staff even at 1HP. Darting Blow and Atk/Spd2 are also options, both of which can compensate for speed on a +Atk Nina. Def Smoke shines when Nina is supported by multiple dancers, effectively pumping up her damage by 28 on nearby targets after first. Other options for her C and Seal include Ploys; Def Ploy works off her good Res stat in order to increase the damage output of a quad by up to 20 if it lands. Similarly Spd Ploy can help her turn doubles into quads. However her C and Seal are flexible. Spd Smoke, Savage Blow, Atk or Spd Waves and team buffs are all options.
