See the IV Checker for All Units

Trait Fruits—How to Change IVs

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Atk/-Def

The best IVs for Ninja Lyn are +Atk and -Def. Since her weapon can nail second strikes, and her kit is designed to make it easy for her to nail quad-attacks, getting a +Atk IV would be best in significantly increasing her damage. Her Def is of less importance so it can be safely taken as his bane.

Additionally, her +Atk is a superboon so you should take advantage of it as much as possible.

Ninja Lyn Best Builds

Desperation Ninja Lyn

： Tailwind Shuriken ： Reposition ： Moonbow ： -

： Atk/Spd Push 4 ： Desperation 3 ： Spd/Def Rein 3 ： Brazen Atk/Spd 3 ： -

How to Use, Explanation

A build relying on Desperation for lots of one-sided matchups. Once she reaches Depseration range, she can sweep through teams so make sure to support her with refresher-assist allies.

Offensive Ninja Lyn

HOT
： Tailwind Shuriken ： Reposition ： Moonbow ： -	： Swift Sparrow 3 ： Chill Atk/Def 2 ： Spd/Def Rein 3 ： Swift Sparrow 2 ： -

How to Use, Explanation

A simple player phase build for Ninja Lyn that maximizes her damage through Atk and Spd. Quad attacks will be very common when running this build so expect little foes surviving the onslaught of shurikens.

Aether Raids Ninja Lyn

HOT
： Tailwind Shuriken ： Reposition ： Glimmer ： -	： Fury 4 ： Disarm Trap 3 ： Spd/Res Rein 3 ： Fury 3 ： -

How to Use, Explanation

This build is made specifically for Aether Raids. Utilizing Lyn's sheer firepower, she can go in without worrying about setting off any traps, while taking Fury damage. Activate her Duo skill to attack again to bring her HP even lower and then bring the rest of your allies in if they Wings of Mercy 3.

Arena Offense Ninja Lyn

HOT
： Tailwind Shuriken ： Reposition ： Ruptured Sky ： -	： Swift Sparrow 3 ： Windsweep 3 ： Spd/Res Rein 3 ： Swift Sparrow 2 ： -

How to Use, Explanation

This build is for Arena, which gives Lyn pure offensive tools. With Ruptured Sky, she can take care of any tough foes (especially dragons), and Windsweep 3 ensures that she stays safe as she is very fragile.

Ninja Lyn Roles, Strengths, and Weaknesses

Ninja Lyn Roles

Lyn - Ninja-Friend Duo Roles
Close-Physical	Ranged-Physical	Close-Magic	Ranged-Magic
Physical Wall	Magic Wall	Effective Weapon	Movement Assist
Exclusive Skill	All-Range Counter	Recovery	Refresher
Legendary	Mythic	Duo / Harmonized	Resplendent

Ninja Lyn is a ranged physical attacker (range = 2). Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent to her Atk minus the foe's Def stat.

Duo Skill Usable in Arena

Ninja Lyn's Duo Skill raises her arena score, in addition to unleashing a powerful battle effect. Duo Heroes have a Duo Skill which can be used once per map. Additionally, her Duel effect treats her stats as 190 in Arena modes, giving her a huge advantage over many other heroes.

The effect of Lyn's Duo Skill is shown below

Her duo skill grants her an additional action. It will only work if she has already entered combat in said turn so make sure she is able to land an attack beforehand. This duo skill can only be used once per map.

You can read the in-game text for Ninja Lyn's duo skill and the duel component in this section!

Ninja Lyn Strengths

Access to a Duo Skill

As discussed above, Ninja Lyn has access to a duo skill that grants her an additional action. Though this can only be activated once per map, it will provide her with enough room for the powerful Tailwind Shuriken to take out even the most durable of enemies. Use it well!

Since Tailwind Shuriken is a dagger, this means that by the second action, your enemy will be most likely already inflicted with 【Dagger ７】. This makes the chance of taking out the affected enemy very high.

Nail consistent quad-attacks with Tailwind Shuriken!

Tailwind Shuriken is similar to a Brave weapon in the sense that it allows its user to score 2 strikes in one attack if they initiate damage. This is an extra attack and not a follow-up attack so when you are able to get an outspeed, Ninja Lyn can land 4 strikes in one action. This makes her a very powerful player phase attacker. Another key difference between her weapon and Brave weapons is that Tailwind Shuriken grants +4 Spd unlike Brave weapons that inflict a Spd penalty. This makes scoring quad-attacks very easy for Lyn.

Like most daggers, it inflicts a -7 Def/Res debuff to target and all foes within 2 spaces of target after combat. As mentioned, this can be easily taken advatange of Lyn when using her Duo Skill.

Create an amazing gap between your offenses (Atk/Spd) and the enemy defenses (Def/Spd) to deal huge amounts of damage

The fan favorite Swift Sparrow 3 grants Ninja Lyn +6 Atk +7 Spd in the player phase to help Tailwind Shuriken's knock-out potential. In addition, Spd/Def Rein inflicts -4 Spd/Def on any enemy within 2 spaces of Lyn.

Combined, these two effectively gives +10 Atk +11 Spd to Ninja Lyn. This makes a lethal quad-attack from her very easy to score.

Ninja Lyn Weaknesses

Weak defenses

Ninja Lyn's defensive stats are not very high and considering that Tailwind Shuriken inflicts -4 Def/Res to her, she is very vulnerable to strong attacks. Losing her in battle would be detrimental to your team as she provides lots of knock-out potential on a wide range of units. Use her flying movement to position her away from units that can easily take her out.

Weak to bows

As a flying unit, X takes 1.5x damage from bows and weapons effective on flying units. Be sure to keep them out of the range of archers and leave them to other units.

Ninja Lyn Team and Counters

Teammates for Ninja Lyn

Brave Roy	Mirabilis	Summer Byleth (F)	Cordelia
Legendary Azura	New Year Peony	Eir	Pirate Tibarn

Dancers with Wings of Mercy

Ninja Lyn has a lot of firepower at her fingertips. If she's running Fury 4 , she can attack, use her Duo skill, and then attack again to get her HP low enough for her dancers to activate Wings of Mercy.

Galeforce Units

Keeping on the same vein as above, if Ninja Lyn's HP is low enough to activate Wings of Mercy, any other teammates with Wings of Mercy and Galeforce equipped can swoop in to clean up the rest of the enemy units.

Ninja Lyn Counters

Masquerade Sigurd	Brave Hector	Seiros	Cecilia
Brave Ike	Fallen Lyon	Brave Edelgard	Valentine's Gustav

Despite being an extremely powerful unit, Ninja Lyn does face difficulty against these certain units.

Units that have weapon triangle-effectiveness against her like Cecilia and Fallen Lyon should be able to take her out.

Tanky units should be able to take hits from her, especially if they have Distant Counter equipped, more so with the Deflect Missile 3 Sacred Seal equipped.

You can also protect your team if you equip any of these tanks with A/R Far Save 3, as she will not be able to take out the more fragile units when they step in to take damage for them.

Do note, however, that their effectiveness will vary from how you build them, if they're merged up, as well as how invested the opponent's Ninja Lyn is.
