Tana

Weapon: Firesweep Lance+ / Flowing Lance (+SPD) / Ninja Yari+ / Slaying Lance+ (+SPD) 

Assist: Positional Assist / Flexible

Special: Luna / Moonbow / Glimmer / Galeforce

Passive A: Life and Death / Atk/Spd Solo / Swift Sparrow / Atk/Spd Push / Impact Skills

Passive B: Aerobatics / Chill Skills / Hit and Run / Dive-Bomb 

Passive C: Rein Skills / Joint Drive Skills / Odd Tempest / Guidance / Flexible

Sacred Seal: Atk/Spd Solo / Life and Death / Swift Sparrow / Death Blow 

• Tana’s respectable offensive lean combined with her flexible maneuverability and other flier advantages allow her to shine on the frontline with a damage-oriented set. Increasing either of her offenses with the appropriate Asset—though a +SPD IV is slightly preferable here—is recommended here. 
• She fortunately has a few choices as far as her weapon goes, with the best choice depending on personal preference as well as general availability. For any refineable weapons, +SPD is best for more consistent follow-ups. 
  • Firesweep Lance is a standard choice to fully lock her into a Player Phase playstyle, negating her foe’s counterattacks upon initiation; this makes her a much safer fighter and also lets her safely equip Life and Death. However, she will have her own counters disabled during the Enemy Phase. 
  • Flowing Lance is an excellent choice to break through enemy bonuses through its innate Lull Atk/Def—a skill she normally cannot equip—and adopt a more generalist approach. In a similar vein, Slaying Lance helps her damage through faster Specials.
  • Ninja Yari is the scarcest of the aforementioned options, but works excellently to have Tana leverage her Speed for a quad-strike setup. This pairs especially well with Dive-Bomb if available. 
• Any A skill that boosts Tana’s Attack and Speed simultaneously will work here, with Life and Death being a potential option if using Firesweep Lance since she won’t have to worry about being attacked (typically) in that case. If she is equipped with anything other than Firesweep Lance, Sturdy Impact—and to a lesser extent, Mirror Impact—works excellently to offset the loss of counterattack negation through safer initiations. 
• Chill skills—to provide both a boost to her own performance and that of her allies—and movement-based skills like Aerobatics, Flier Formation, and Hit and Run synergize perfectly with the aggressive nature of this set. For non-Firesweep sets (and especially if using Ninja Yari), Dive-Bomb is an exceptional B skill choice to immediately access a Desperation effect without needing any setup.
• Tana’s C and Sacred Seal slots are entirely flexible, with skills that help push her damage higher being highly recommended. Ultimately, though, anything that complements her team will realistically work, including her base Guidance.

Weapon: Vidofnir (+EFF/+SPD/+DEF)

Assist: Positional Assist / Flexible

Special: Bonfire / Sol / Luna / Moonbow

Passive A: Close Def / Atk/Def Solo / Atk/Spd Solo / Sturdy Stance 

Passive B: Quick Riposte / Guard Bearing / Mystic Boost

Passive C: Smoke Skills / Joint Drive Skills / Rein Skills / Flier Buffs / Flexible

Sacred Seal: Atk/Def Solo / Close Def / Quick Riposte / Sturdy Stance

• This set diverges from the Winged Princess’s typical playstyle and instead places an emphasis on her Enemy Phase performance to make the most of her refined Vidofnir’s effect. An enhancement to Attack or Speed will once again work well here, but Tana also appreciates receiving her four-point +DEF IV to further reduce the damage she takes from physical foes. For Vidofnir’s refinement, taking the unique option works nicely in mixed teams, but taking a +SPD or +DEF refine may also be worthwhile.
• For Tana’s Special, Bonfire scales quite well with the focus on amping up her in-combat Defense stat and comes with a reasonable cooldown to boot. However, a healing Special (i.e. Sol and Noontime) are also useful for greater longevity, or even Luna and Moonbow to burst through bulkier opponents.
• Equipping Close Def as her A skill is the natural choice given that Vidofnir already carries a similar effect built-in, further enhancing her durability against melee threats. However, other alternatives include a Solo skill—likely either Atk/Def Solo or Atk/Spd Solo—to grant Tana some dual phase functionality, or Sturdy Stance 3 for its Guard effect during the Enemy Phase. 
• Her B slot options are more than a little limited due to flier inheritance restrictions, but some good skills do still exist. Besides the obvious Quick Riposte to ensure her follow-up attack during the Enemy Phase, Guard Bearing is a powerful—albeit high investment—skill to halve the first damage Tana would take during each Enemy Phase. Although she’s not able to fully leverage all of its effects, Tana can make good use of Mystic Boost’s passive healing to enhance her sustain. 
• Smoke skills inherently go well with this defensive playstyle, but Tana is once again not tied to any given C skill so pretty much anything can work here. For her Sacred Seal, she should ideally equip something that augments her key stats or Quick Riposte if it is not already being used in her B slot. 

Weapon: It’s Curtains…+ (+ATK) 

Assist: Positional Assist / Flexible

Special: Galeforce

Passive A: Heavy Blade 4 

Passive B: Wings of Mercy / Hit and Run

Passive C: Smoke Skills / Odd Tempest / Joint Drive Skills / Flexible

Sacred Seal: Quickened Pulse 

• Although this build retains an aggressive Player Phase approach, it instead assumes Tana is being used specifically within Galeforce-centric compositions for use in Aether Raids Offense—rather than general gameplay. Tana prefers a +ATK IV here over any other options to ensure her Heavy Blade activations, as this is crucial to her success. 
• The main purpose of this set is to leverage Galeforce’s self-refreshing quality to have Tana and her allies quickly neutralize the opposing Defense team during the Player Phase; in turn, however, one must work around Galeforce’s lengthy cooldown. 
  • This can most efficiently be done through an Attack-refined It’s Curtains…, which immediately drops Galeforce’s cooldown down to three. Alongside Heavy Blade and the Quickened Pulse Sacred Seal, this lets Tana activate it in a single hit as long as Heavy Blade activates. It’s Curtains… can potentially be swapped out for a more generally useful weapon if Velouria’s Wolfpup Fang support is available.
• Wings of Mercy is a prime B skill choice to get close to the enemy team with ease, allowing Tana to bypass the need for outside assistance such as from an Assist like Smite. A displacement skill like Hit and Run may also be worth considering to quickly retreat after activating Galeforce.
• Smoke skills—and to an extent, Savage Blow—are a natural choice to help Tana and other allies sweep through the enemies with greater ease. Joint Drive skills also stand out to mutually buff herself and nearby allies in the Galeforce chain. Odd Tempest is an incredibly rare—but equally lucrative—C skill to grant her cavalry-esque mobility with the advantage of being unhampered by terrain, though this is unnecessary if something like Duo Palla support is already available in the same team.
