Ayra

Weapon: Ayra’s Blade (+Eff)

Assist: Positional Assist / Flexible

Special: Regnal Astra

Passive A: Distant Counter

Passive B: Spurn / Null Follow-Up 

Passive C: Joint Drive Skills / Smoke Skills / Time’s Pulse / Flexible

Sacred Seal: Atk/Spd Solo / Mystic Boost / Quickened Pulse

• Ayra’s two exclusive abilities are by far her most defining features, and this set aims to maximize the usage of both to let her excel both on the offensive and defensive. It’s essentially something similar to the set that led to her original notoriety—just updated for current standards. Ayra covets a +SPD IV here over all else, though a +ATK IV is workable if unavailable. 
• Combining Regnal Astra with Ayra’s Blade and Distant Counter provides the warrior princess immense combat prowess; since her refined PRF stops foes from preventing her Special activation, Ayra can consistently leverage her high damage output ability to function as a versatile counter without necessitating that she initiate combat herself.
• She has two main B skill choices to consider here, and they both have their merits: Spurn and Null Follow-Up. 
  • Spurn provides Speed-based damage reduction to grant Ayra much greater survivability (as her inherently high Speed renders it simple to maintain its maximum effect), and also supplements her Regnal Astra damage. This is largely redundant if Flayn support is available, however. 
  • In contrast, Null Follow-Up is a formidable B skill that helps Ayra can engage in combat without fear of either having her offensive capabilities hampered or being potentially shut down by foes with automatic follow-ups; it doesn’t directly enhance her survivability like Spurn, but it does give her much greater applicability. 
    • Null Follow-Up can also be paired with the Mystic Boost Sacred Seal (since using Spurn makes it harder to use something other than a stat booster) if Ayra’s longevity becomes too much of a concern.
• Joint Drive Spd works excellently in Ayra’s C slot to build upon her Speed for improved performance across the board—you literally cannot have enough Speed with her—and some minor ally support. Smoke skills and Time’s Pulse may also be worthwhile considerations, but ultimately her C skill choice is flexible. 
• The Atk/Spd Solo Sacred Seal lends itself perfectly to Ayra’s intended playstyle here, granting a fearsome offensive boost in both phases. As previously mentioned, if Null Follow-Up is equipped, Mystic Boost works wonderfully to make up for the loss of Spurn’s supplemental damage reduction through consistent healing. Quickened Pulse is an option as well to immediately let Ayra access Regnal Astra.

Weapon: Ayra’s Blade (+Eff)

Assist: Positional Assist / Flexible

Special: Noontime / Sol

Passive A: Distant Counter

Passive B: Null Follow-Up / Null C-Disrupt / Lull Atk/Spd 

Passive C: Smoke Skills / Joint Drive Skills / Flexible

Sacred Seal: Spd/Res Solo / Atk/Spd Solo / Swift Stance / Kestrel Stance / Quick Riposte

• This build optimizes Ayra for a more defensive-leaning role reminiscent of standard tanks, though backed by her fantastic versatility. A +SPD IV is ideal once again as Ayra will be primarily dependent on her ability to naturally perform and avoid follow-ups for her longevity, but +ATK and +RES (strictly for Aether Raids Offense) are decent alternatives as well. 
• Ayra should swap out Regnal Astra for a healing Special given the greater focus on tanking here, as her refined weapon’s damage reduction alone generally won’t be sufficient to cover her fully—especially against foes who can exploit her poor Resistance. Noontime is best for an instant activation on each counterattack, though Sol can be used with accelerated cooldown support (e.g. Brave Lucina’s refined Geirskögul).
• Distant Counter is once again recommended to maximize Ayra’s matchup spread. Null Follow-Up is undoubtedly her best B skill choice as it negates effects most detrimental to her performance and instead forces her opponents into a regular Speed contest, the likes of which she would win. Other options include Null C-Disrupt and Lull Atk/Spd, but they are not nearly as universally useful. 
• Ayra isn’t at all attached to a specific C skill and most will generally work provided that they assist her or her team in some way, though Smoke skills and Joint Drives are always solid choices. In the context of Aether Raids Offense, Pulse Smoke is particularly lucrative to reduce the effectiveness of Infantry Pulse compositions. 
• Any Sacred Seal that builds upon her key stats will likely work here, with Solo skills being highly recommended for their easily fulfilled requirement and strong accompanying boosts. If using something other than Null Follow-Up as her B skill, Ayra can make good use of Quick Riposte to break through follow-up denial effects. 

Weapon: Ayra’s Blade (+Eff)

Assist: Positional Assist / Flexible

Special: Regnal Astra / Galeforce 

Passive A: Swift Sparrow / Atk/Spd Solo / Atk/Spd Push / Flashing Blade

Passive B: Null Follow-Up / Wings of Mercy / Lull Spd/Def / Desperation

Passive C: Time’s Pulse / Smoke Skills / Joint Drive Skills / Flexible

Sacred Seal: Atk/Spd Solo / Flashing Blade / Quickened Pulse / Swift Sparrow 

• Ayra also has the option to simply focus entirely on her Player Phase prowess and adopt an overall more aggressive playstyle. Surprising absolutely no one given this set’s focus on her offensive ceiling, improving either one of Ayra’s offensive stats with an Asset is once again ideal. 
• Her signature Regnal Astra is the obvious choice if maximum damage potential is preferred, though Ayra can potentially replace this Special in favor of Galeforce for a more mobility-based strategy. It does come with a stringent five-turn cooldown, but her PRF’s Slaying effect means that she can easily activate it with Flashing Blade as long as she doubles. 
  • The Guard-nullification aspect of Ayra’s Blade does make her an exceptionally great choice of unit for Galeforce strategies within Aether Raids Offense as well, though using her within this context does make it much more important to reduce its cooldown as much as possible. 
  • For maximum effectiveness, Ayra should ideally be able to activate Galeforce on her first hit rather than the second by reducing its base cooldown. This can be done by making Flashing Blade her A skill and equipping both Time’s Pulse and the Quickened Pulse Seal, or with outside Infantry Pulse support. 
• Any standard offensive A slot skills that enhance both Attack and Speed (such as her base Swift Sparrow) will work here, solidifying Ayra’s damage output. Specifically if using her within a Galeforce-centric composition for AR-O, she can also utilize Flashing Blade 4 in her A slot to free up space for the Quickened Pulse Sacred Seal.  
• For her B slot, Null Follow-Up further assists Ayra in ensuring her follow-up attack, negating skills that would otherwise prevent it. Mobility-based options like Wings of Mercy also complement this build’s intended playstyle (especially for Aether Raids), as do more aggressive skills like Lull Spd/Def and Desperation. 
• Time's Pulse is an exceptional C skill that allows Ayra to access Regnal Astra twice in a single round of combat, and also has its uses with Galeforce as mentioned previously. Besides this, Smokes skills work great to enhance the quality of Ayra’s subsequent battles, and Joint Drive skills carry useful mutual buffing utility. 
• Aside from Flashing Blade and Quickened Pulse to accelerate her Special activations, any available Sacred Seal that boosts Ayra’s offensive stats fits well.
