Spring Inigo

Weapon: Firesweep Bow+ / Springy Bow+ (+SPD) / Brave Bow+

Assist: Positional Assist / Flexible

Special: Luna / Moonbow / Glimmer 

Passive A: Swift Sparrow / Atk/Spd Solo / Sturdy Impact / Death Blow 

Passive B: Aerobatics / Chill Skills / Wings of Mercy / Desperation

Passive C: Rein Skills / Joint Drive Skills / Flexible

Sacred Seal: Swift Sparrow / Atk/Spd Solo / Sturdy Blow / Quickened Pulse / Heavy Blade

• Spring Inigo’s offensively oriented statline and flexible flier mobility lends itself well to aggressive play; this build aims to capitalize on just that. A +SPD IV is generally ideal to maximize his proficiency at performing follow-up attacks (which is especially important if equipped with Firesweep), but +ATK also works well to frontload more raw damage. 
• A Firesweep Bow helps mitigate Spring Inigo’s relatively unimpressive physical bulk and makes his combat performance much safer overall, negating his opponent’s counterattacks upon initiation. Alternatively, his base Springy Bow may be kept to work around enemy debuffs to his two most important stats (and comes with an appreciable offensive boost to boot), or Brave Bow for +ATK variants or potentially quad-strikes. 
• Any A skill that enhances both his Attack and Speed works well here to maximize his damage potential, though Death Blow does make for a worthwhile consideration if using Brave Bow. Additionally, though quite costly, Sturdy Impact is an exceptional candidate if not using Firesweep to improve Spring Inigo’s survivability against physical threats. 
• Ranged fliers are unfortunately somewhat lacking in terms of good B skills, but Spring Inigo isn’t completely out of luck. Aerobatics, Wings of Mercy, and other movement-based skills are quite useful to more easily narrow in on the enemy team, though Chills may also be considered to debilitate enemy foes consistently. The standard Desperation (if not using Firesweep Bow) is also an option as well to let Spring Inigo freely perform consecutive follow-up attacks upon taking enough damage; this pairs well with Fury and Push skills.
• His C slot is flexible, with good options being anything that helps further enhance his own performance like his base Atk/Spd Rein and Joint Drives (which also provide support to his allies). For his Sacred Seal, anything that augments his key offensive stats is recommended, though Quickened Pulse and Heavy Blade also help his damage through quicker access to his Special. 

Weapon: Spendthrift Bow+ (+SPD) / Springy Bow+ (+SPD) 

Assist: Positional Assist / Flexible

Special: Noontime / Moonbow / Sol

Passive A: Atk/Spd Solo / Atk/Def Solo / Stance Skills / Close Foil 

Passive B: Mystic Boost / Quick Riposte 

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

Sacred Seal: Iote’s Shield / Atk/Def Solo / Spd/Res Solo / Mystic Boost / Quick Riposte

• Although the Festival Flower’s statline and innate strengths clearly gear him toward an offensive playstyle, Spring Inigo can work defensively for the truly dedicated; investment and intensive support will be key here to ensure his success at such a role. A boost to either one of his offensive stats works well once again, though a +RES IV may also be considered to lean him more towards magical tanking if so desired. 
• The inheritable Spendthrift Bow is undoubtedly Spring Inigo’s best weapon choice for this build, improving his damage output and raw durability by a substantial amount. It does come with a slight demerit, but it can be worked around without that much difficulty (especially if Brave Lucina support is available). His native Springy Bow’s pseudo-debuff immunity makes it a solid alternative.
• Equipping a healing Special is recommended to grant him a consistent source of sustain for greater longevity. Noontime is generally preferred over Sol for its faster activation rate, though one can potentially use something that boosts his damage if confident enough in his survivability without healing.
• Solo skills provide an ample helping of stats and come with dual-phase functionality, but Stance skills can also be considered for their built-in Guard effects; this is particularly beneficial for his matchups against foes with automatic doubles. Lastly, Close Foil and Close Counter are other options for a more traditional tanking playstyle, but are the trickiest to pull off successfully. 
• Mystic Boost is one of Spring Inigo’s better B skill options, coupling a solid post-combat healing effect with useful protections against dragons and staff users; it can also be used as his Sacred Seal. Although his high Speed may make Quick Riposte seem unnecessary, it’s worth noting that he has no way of bypassing follow-up negation effects (as he cannot access Null Follow-Up due to being a flier) outside of using this skill. The C slot is flexible.
