Ninja Lyn

Weapon: Tailwind Shuriken

Assist: Positional Assist / Flexible

Special: Moonbow / Glimmer / Ruptured Sky 

Passive A: Swift Sparrow / Sturdy Impact / Death Blow 4

Passive B: Chill Atk/Def / Desperation / Aerobatics / Flier Formation

Passive C: Spd/Def Rein / Flexible

Sacred Seal: Swift Sparrow / Death Blow / Atk/Def Solo / Sturdy Blow

• This build is a pretty standard offensive build meant to highlight Ninja Lyn’s exceptional Player Phase strength; her stellar base offenses alongside her Tailwind Shuriken, self-refreshing capacity, and flier mobility all together make her an effective frontline force. Increasing either Ninja Lyn’s Attack or Speed with the appropriate IV is thus recommended to complement this role. Note that although alterations can always be made, she can work perfectly fine here with her base kit alone. 
• Specials with low cooldowns (i.e. Glimmer, Ruptured Sky, and her native Moonbow) take full advantage of Tailwind Shuriken’s built-in Brave and Slaying effects, being guaranteed to activate on her second attack and potentially an additional time if she successfully lands a quad strike. In exchange for less frequent activations, Luna may be considered for its greater burst potential. 
• Ninja Lyn’s base Swift Sparrow works perfectly here and serves to further augment her presence during the Player Phase. However, there are alternatives should one feel sufficiently confident in her ability to perform follow-ups without Swift Sparrow’s Speed boost, or if simply focusing on damage alone without regard for her quad-strike potential altogether. Most notably, Sturdy Impact and Mirror Impact help make Ninja Lyn’s initiations much safer through massive defensive boosts and a denial of enemy doubles, though Death Blow is the better choice from a pure damage perspective. 
• Her B slot options are a bit limited due to flier skill restrictions, but she does have a few candidates nonetheless. Her native Chill Atk/Def is useful to enhance her damage output and survivability against the foe targeted by its debuff, though for quad-strike oriented sets Desperation may be better to land them safely without worry of enemy retaliation. Although they don’t directly affect her combat, Aerobatics and Flier Formation are potential options to maximize the flexibility of Ninja Lyn’s flier movement. 
• Spd/Def Rein is likely Ninja Lyn’s best choice of C slot here and complements this build’s damage focus by weakening the foe considerably through in-combat debuffs. Alongside Tailwind Shuriken’s built-in Def Smoke (which stacks with Rein skills) and her Duo Skill’s self-refresh, she can greatly lower her opponent’s stats by herself for markedly improved combat performance. 
• Any Sacred Seal that increases her key stats will fit perfectly; her best choices include Swift Sparrow, Death Blow, Sturdy Blow, and Atk/Def Solo.

• Although this build once again focuses on Ninja Lyn’s applications during the Player Phase, this assumes the context of Aether Raids Offense and concerns her place in Galeforce-centric teams by becoming a beacon for other allies equipped with Wings of Mercy to quickly close in on the enemy composition. 
• The success of this build is centered around two crucial factors: Fury 4 and her Duo Skill. Please note that if Fury 4 is not available, this build will not work consistently in most cases. The game plan itself is relatively simple and has Ninja Lyn initiate combat three times in a single Player Phase—once with her original action, the second with her Duo Skill’s refreshing effect, and the third with the assistance of a refresher. Combined with Fury 4, this will inflict a total of 24 chip damage on Lyn and easily puts her in Wings of Mercy’s threshold up until she goes over 48 HP. 
  • If one finds that she somehow crosses this 48 HP cap (meaning 49+ HP), her Tailwind Shuriken will have to be swapped out for Pumpkin-a-Box if still wanting to utilize Ninja Lyn as a Wings of Mercy beacon. However, this comes at the cost of losing out on the main advantage of using Ninja Lyn for such a purpose to begin with: the ability to wield her PRF’s significant offensive edge at the same time. 
  • The reason the much more readily available Fury 3 won’t work (for the most part) with Tailwind Shuriken is that after her three engagements, this puts her at a total health loss of 18 HP. This in turn means that in order to actually trigger Wings of Mercy, the most Ninja Lyn’s HP could be is 36 which is only possible via an unmerged -HP copy with no room for fluctuation from factors such as bonus week, Summoner Support, or Dragonflowers. 
• Beyond the self-inflicted damage component of this set, there are other considerations to make. In particular, Disarm Trap is highly recommended to safely carry out Ninja Lyn’s setup without worrying about trap placement disrupting this strategy. Attempting to use her without Disarm Trap involves much higher risk but if it is entirely unavailable, B slot skills that operate at low HP like Desperation and Escape Route are possible alternatives. 
• Using Savage Blow as her designated C and/or Sacred Seal slot is effective to freely chip at her enemies health (who are more than likely to be grouped together) with her repeated strikes for her allies to potentially KO them in a single hit; this can also help knock foes down below Guard’s HP threshold, a skill detrimental to Galeforce strategies. Alternatively, Spd Smoke or Atk Smoke can be equipped if her paired teammates are dependent on skills like Flashing Blade or Heavy Blade to accelerate their Special charge, or the Death Blow Sacred Seal if wanting to boost Lyn’s own damage.

Assist: No Assist / Positional Assist

Passive C: Ground Orders / Air Orders / Panic Smoke / Distant Guard / Flexible

• Ninja Lyn’s ability to enable the Duo’s Hindrance structure in Aether Raids Defense teams—not to mention her ranged status, notable offensive presence, and access to movement-based skills—may make a set dedicated to such an environment quite worthwhile for some. A +ATK IV will generally be Lyn’s ideal choice to frontload as much damage as possible with her first two strikes, though +SPD is welcome if the former is unavailable.
• Her Special should once again be filled by a low-cooldown choice. Given the common presence of high Attack foes in incoming Offense teams (as well as dragons during Light season), Ruptured Sky is an especially attractive option in the context of a Defense team, though Moonbow and Glimmer are still fine if it’s not available. Lyn’s choice of Assist is important too as one must account for the order in which the AI prioritizes turn order, though one can choose not to use one at all to avoid any potential mishaps.
• Impact skills are a natural choice to enhance Ninja Lyn’s survivability through a massive augmentation to one of her defensive stats and denial of her chosen foe’s follow-up attack; this helps her avoid the undesirable scenario of being outright OHKO’d should her initial attacks prove insufficient and be able to attack multiple times instead. Sturdy Impact and Mirror Impact also come with a solid boost to her damage as well to boot. 
• Aerobatics (or Flier Formation in flier-heavy compositions) is solid to expand her effective range and potentially catch challengers off-guard; Wings of Mercy serves a similar purpose, though fits better if Ninja Lyn is run alongside units who can easily reach low HP without outright dying. If nothing else, Chill skills like her base Chill Atk/Def can be equipped to fill in holes in terms of the range of debuffs one’s team can apply through the skills of other allies or structures. 
• Order skills are absurdly strong in Aether Raids Defense maps and allow Ninja Lyn to provide a valuable boost to her teammate’s overall maneuverability. This is especially useful in tucking away particularly fragile allies without necessarily sacrificing range, but the uses of Order skills are overall quite varied. Panic Smoke may also be worthwhile to debilitate enemy foes and make the use of visible buffs much riskier. If all the aforementioned are unavailable or taken care of by other allies, it’s always an appreciated recourse to simply slot in-combat buffs like Distant Guard or Drives. 
• The Sturdy Blow and Atk/Def Bond Sacred Seal are notable for boosting both Lyn’s damage and resilience to physical hits, while being active fairly consistently; Solo seals are much more unreliable here. Alternatively, Hardy Bearing can be used to shut down Vantage units and other foes who rely on specific combat order to function, or Quickened Pulse to use Luna for her Special instead.
