Ninja Navarre

Weapon: Ninja Yari+

Assist: Positional Assist

Special: Moonbow

Passive A: Flashing Blade 4

Passive B: Lull Spd/Def

Passive C: Drive Spd / Flexible

Sacred Seal: Swift Sparrow 2 / Darting Blow 3 / Death Blow 3

• Ninja Navarre comes with a quite cohesive base kit that immediately launches him to immediate performing success. As such, the only skill inheritance necessary is whichever positional assist you need (Reposition and Draw Back are relatively splashable) and, for low-investment purposes, literally anything goes in his C slot.
• The fat of the build lies in the combination of Ninja Yari, Flashing Blade 4, Moonbow, and Lull Spd/Def, all of which synergize together like a finely-tuned clock. The fine mechanics from here are simple:
  • Lull Spd/Def and Ninja Yari's +4 Speed bonus together stack even more Speed than is competitively healthy, allowing Flashing Blade to activate nearly all the time.
  • Ninja Yari's twice-attacking nature allows Navarre to deal nice blitz damage in a single round while charging his Special even faster than he would with single hits.
  • Altogether, under easy conditions, Navarre consistently activates Moonbow in single rounds, as well the true damage component of Flashing Blade 4. Provided you're not pushing it against extremely high Defense units, expect Navarre to deal it fast and furiously.
• Navarre's Sacred Seal is pretty obvious at this point for a player phase-attuned build. Swift Sparrow provides the best of both worlds in initiating Atk/Spd, while Darting Blow or Death Blow are more specialized options for Flashing Blade activation or more raw damage, respectively.

Weapon: Ninja Yari+

Assist: Positional Assist

Special: Luna / Galeforce / Moonbow

Passive A: Flashing Blade 4 / Swift Sparrow 3 / Most other Atk/Spd-based A slot skills

Passive B: Lull Spd/Def

Passive C: Time's Pulse

Sacred Seal: Swift Sparrow 2 / Flashing Blade 3 / Death Blow

• This does a lot of what the previous build was purposed to do, but the mere main addition of Time's Pulse and its -1 cooldown precharge (provided Navarre's chosen Special hasn't been charged at all at the beginning of a turn) does open up a few fantastic opportunities in Specials.
  • Taking Flashing Blade, Time's Pulse, and Ninja Yari hitting twice into consideration, players can do a simple substitution of Moonbow to Luna. As was the case with Moonbow, Luna benefits from rapidfire activations on Navarre's second hit, and can potentially deal more serious burst damage especially against high Defense targets.
  • Likewise, Galeforce benefits from Ninja Yari's unhindered second hits and Time's Pulse's cooldown reduction. Navarre can gain an extra action in a single round assuming 1) Flashing Blade activates with no hinderances such as Guard, and 2) the second hit of Ninja Yari lands true.
• Another potential investment decision you can make on this build is swapping Flashing Blade 4 for a dedicated Atk/Spd A-slot skill while using Flashing Blade instead as the Sacred Seal. The main reason you may consider doing this is to lessen the margin of error when it comes to activating Flashing Blade. For example, a fourth-tier A slot skill such as Swift Sparrow 3 plus the Flashing Blade Seal has a higher chance of accelerating Navarre's Special as opposed to Flashing Blade 4 + Swift Sparrow 2 Seal. You should only consider this if getting Navarre's cooldown accelerated at any cost is top priority.
• You can opt to due a pure damage-focused version of this build, which would run stat boost skills over Flashing Blade. In this case, Moonbow is back on the menu as its single round activation is still possible thanks to Time's Pulse.

Weapon: Slaying Lance+ (+Spd) / Flowing Lance+ (+Spd)

Assist: Positional Assist

Special: Noontime / Sol / Aether

Passive A: Distant Counter / Atk/Spd Solo / Flashing Blade 4

Passive B: Spurn / Close Call / Repel

Passive C: Atk Smoke / Pulse Smoke

Sacred Seal: Spd/Res Solo

• Lack of an amazing unique weapon aside (where which lance competitors such as Kris and Legendary Dimitri excel), Navarre has the raw offensive stats to pull off a very effective damage reduction build—an effective trend for most fast melee infantry units thanks to Spurn, Close Call, or Repel. As a result, Navarre gains some rather neat defensive value due to greatly reduced incoming damage as well as many typical enemies being unable to surpass his Speed.
• Running one of the aforementioned B slot skills, Navarre's Speed becomes even more important to invest in; the amount of damage reduced scales off of the difference between Navarre and his opponent's Speed (for a maximum of 40% reduction).
  • As such, Spd/Res Solo is this build's best Sacred Seal bar little else; it serves as a vital increase to both Navarre's Speed and only decent Resistance.
  • Speed refinery on any weapon Navarre chooses should be an obvious choice. A couple of recommendations in this case are:
    • Slaying Lance is renowned for its simplicity and accessibility; it decreases the full cooldown of Navarre's chosen Special. In particular, Sol bodes well when combined with the -1 CD and Geirskögul support.
    • Flowing Lance is seasonal (saved by its native wielder's 4 star rarity), but is a rather significant choice due to its inbuilt Lull Atk/Def effect, which improves Navarre's bulk and offense.
• Distant Counter gives Navarre the ability to counterattack ranged enemies, which are commonplace pretty much anywhere but especially Aether Raids. Playstyle differences may guide you to Atk/Spd Solo, which improves Navarre's dual phase capabilities, or Flashing Blade 4, which comes by default on Navarre and serves to improve Sol or Aether's activation timing while dealing true damage (combos well with Spurn!).
• Navarre's last inheritance choice lies in his C slot, which is reserved for whichever Smoke skill you prefer. Atk Smoke will usually do the job by further debilitating incoming damage, though Pulse Smoke is an also-fantastic choice for bringing down most setups reliant on precharged Specials. 

Weapon: Slaying Lance+ (+Spd) / It's Curtains… (+Spd)

Assist: Positional Assist

Special: Galeforce

Passive A: Flashing Blade 4 / Swift Sparrow 3

Passive B: Lull Spd/Def / Wings of Mercy / Desperation

Passive C: Spd Smoke / Time's Pulse

Sacred Seal: Swift Sparrow 2 / Quickened Pulse / Flashing Blade

• Navarre has rather outstanding offensive stats for a lance infantry unit and has very little to lose from substituting his default inheritable weapon with another one. Therefore, a more conventional Galeforce build is definitely on the menu if that's more of your style.
• To tend around Galeforce's awful base cooldown of 5, Navarre will require weapons specializing in cooldown cutting. His two main options here are:
  • The near-always available, more affordable Slaying Lance, which permanently reduces Galeforce's cooldown to a more manageable, Flashing Blade-friendlier.
  • The more elusive, seasonally-limited It's Curtains…, which, much like Navarre's original weapon, greatly reduces the amount of Pulse support necessary to fully charge Galeforce in a single hit—a strategy that tends to be used alongside Wings of Mercy beacons like Eir. It only works Turn 1, though that should be enough for specific purposes.
• The rest of the build depends on which weapons / skills / outsourced support you have access to. Some skill combinations are as follows (assuming you're not running outsourced charging such as Wolfpup Fang or Infantry Pulse):
  • Slaying Lance + Flashing Blade 4 + Lull Spd/Def OR Desperation + Swift Sparrow: Conventional build, relies on Navarre hitting two times in a row. Good for most non-Aether Raids content.  
  • Slaying Lance + Flashing Blade 4 + Time's Pulse + Quickened Pulse: Allows Galeforce to fully charge in a single hit assuming Flashing Blade activates, though this is extremely reliant on Navarre's raw Speed without A slot or Sacred Seal modifiers.
  • It's Curtains… + Flashing Blade 4 + Quickened Pulse OR Time's Pulse: Already fulfills 3/5 charges and only requires one successful Flashing Blade-powered hit for one-turn Galeforce.
  • It's Curtains… + Swift Sparrow 3 (or other offensive A slot skills) + Quickened Pulse + Time's Pulse: Completely gets rid of the Speed comparison element of the build (normally the downfall of one turn Galeforce builds) by charging all the way to 4/5.
