Legendary Robin (F)

Intended to fit into a mixed team alongside non DC dragons such as Myyrh or a Tiki with Breath of Fog, the fell dragon serves as the perfect bait for ranged units. Capable of receiving both dragon and flier buffs, you can reach a substantial 38/33 before the distant defense seal.
Though Aether does tend to find itself on a host of characters running steady or warding breath combos, it is here to extend Grima’s ability to refresh after combat. Windsweep allows you to dispatch many of her prominent melee threats in the enemy phase and with the high speed, not only will most units fall under target by Windsweep, but they may also get doubled on their initiation.

Though speed ploy fails to hit significant threats like Fallen Hardin or any of the Naga wielders, it prevents units like Karla and most buffed falchion wielders from doubling Grima on their phase.

Since mine had a defensive bane, I decided to make the most of her neutrality and great offensive stat spread. LnD 3 pushes her offenses to 56/40. In the few occasions she can't ORKO someone, Vantage ensures she gets to counter strike first. Draconic Aura is chosen because she rarely needs her specials help to kill anyone she can double, so Draconic Aura ensures she has her special fully triggered for the next person who challenges her. Being grey and having such a high attack, her special is very capable of OHKOing fully healthy foes.

Robin being a colorless unit may not be as bad as it may seem. Her attacks won’t discriminate against anyone that’s not a Raven tome user. She will be useful in most situations save for Arena runs and battle modes where the enemies’ HP goes above the 50s. With the right team formation and enough supporting skills, Robin is a basically a flying minefield.
With this build and my recommended team formation, her 48 attack without accounting for an A skill turns into *drumroll* 71!
Adding Life & Death gives Robin 76 attack in total, Fierce Stance: 77, Brazen Attack/Speed: 78. And this is WITHOUT summoner support and ally support. Here’s how to do it.

Requirements:
A Slot: Brazen Attack/Speed or Fierce Stance

(I’d warn against using Life and Death since her defenses are already average, and she’d risk dying before she can counterattack then proc Vantage on the next enemy phase. You can easily put her in that Vantage threshold safely by slapping on Ardent Sacrifice/Reciprocal Aid; however, keep in mind that Robin won’t be able to navigate and position herself as easily without Swap/Reposition.)

B Slot: Vantage
Vantage is essential when you’re running an A skill like Fierce Stance and operate by getting in a formation with your fellow fliers.
With Brazen Attack/Speed, you also have the option to equip Robin with Desperation, have her attack, then Reposition/Dance her back to safety.
But this build mostly has Vantage in mind due to being reliant on her teammates to boost her Attack stat. (Friendship does overcome all.)

Special: Glimmer

Pros: This colorless dragon has many good matchups on the enemy phase, particularly against ranged units thanks to her native Expiration. Her base kit also makes it so that there’d be less investment into this Vantage build.
Her other native skill, Resistance Smoke, cancels out the need for an upgraded Lightning Breath. Expiration naturally has 2 more attack than +Attack refined Lightning Breath, and the Resistance Smoke cuts out 7 more resistance. Although a refined Lightning Breath can target the lower defensive stat on an enemy, that wouldn’t be saying much when matching up Robin against a unit like Jakob with even defenses.
When Brazen Attack/Speed or Life and Death is applied, she can take out a ranged unit then apply Resistance Smoke to surrounding enemies, making it more likely for her to kill them on enemy phase.

Cons/Weaknesses:
Dire Thunder, Brave Bows, and possibly the brave melee weapons - On the initial enemy-phase attack, Robin will not survive against these weapons at full HP. Her team comp is moreso focused on attack support, not defense. However, this is pretty typical for a Flier team.
Dragon-slaying weapons - this goes without saying: she will be annihilated when facing Falchion users head-on or the Naga tome on the enemy phase without Vantage activated. However, a certain teammate can cover for her. . .
High resistance melee attackers - can tank 1 hit from Legendary Robin and start shenanigans on the next turn. Having Iceberg or Glacies proc on Robin is not a pretty situation to have either, not to mention Robin can be Ploy-ed to oblivion.

Teammate Recommendations!
Gronraven build Spring Camilla with Triangle Adept, (insert B skill here), Iote’s Shield, Glimmer/Moonbow/Bonfire, and Goad Fliers - can cover two of Legendary Robin’s pivotal weaknesses and provide a great defense against high-resistance lancers as well. She has enough defensive bulk to take burst damage when Triangle Adept can lower the enemy’s attack by 40%.

Kinshi Warrior Hinoka with Desperation, Moonbow/Glimmer/Luna, Goad Fliers, and Drive Attack seal - not only does Hinoka offer the most offensive support to the team combined with her special bow (a whopping +10 to attack when in range), but she can also take care of pesky high-resistance pegasus knights and armored units. What’s that? An armored unit’s HP is too high and they got Wary Fighter? Simply charge up Hinoka’s special and pierce those tanks on the next player phase! What’s that? Moonbow may not be enough to take out an armored unit in one shot? Slap on Quickened Pulse then repeat the instructions above but with Luna (for the cost of 3 attack to the other fliers on the team).

But who should be your third team mate and ultimately Robin’s partner?

*Vanilla Hinoka* with her refined signature Hinoka’s spear, Reposition, Fury, Desperation, Hone Fliers, Heavy Blade seal, and a high map coverage AOE.
Who can say no to a +6 Attack and Speed buff on a base kit benefiting the other 3 fliers on the team? With the support of Kinshi Hinoka and Spring Camilla, her attack and speed will reach greater heights, and her AOE special will do more damage. I would recommend not having the “Blazing” variant of whatever AOE you equip her with since Legendary Robin can pick off the remaining enemies. The special will also guarantee that more units be susceptible to Hinoka’s helicopter antics. Take note to the fact that she is a strong lance wielder. Chrom, Lucina, Alm, and Marth will not stand a chance against her. As for Julia and Deirdre, Legendary Robin can breathe on them, and they will fade from existence. Their defenses are pretty frail as well, so Hinoka might land a KO on the mages if they’re not properly supported. At that point, choosing to defeat Deidre and Naga depends on how you want to position Robin’s team after that skirmish.

Runner-up partner: Lilina with her upgraded Forblaze tome, Glimmer/Dragon Fang, Death Blow, Swordbreaker, her native Spur Attack C skill, Rally Attack, and a Spur Attack seal.
Obviously, she is not a flier and thus wouldn’t be able to support Camilla and Kinshi Hinoka as well in terms of buffing each other and arranging a good flier formation. What DOES work for Robin is her tome’s innate Chill Resistance, but even so, she can only apply this debuff to one enemy at a time per player phase. With this kit, she also fares well against Falchion users and the Naga/Divine Naga wielders.

Bait build Robin. Extremely tanky, extremely lethal. Can tank most initiations, just has to be careful of Falchions. (Great for grinding maps out with Aether. Nearly invulnerable if played right.)

Used in conjunction with NY Azura (Hone Fliers), NY Camilla (Ward Fliers), and any other flier with Goad.

With combat buffs on foe initiation - Robin gains 8 res/def from Camilla and Azura combined, 4 res/def from dragonskin, totalling an additional 12 res/def. For ATK/SPD she gets an additional 10 of each during combat (counting both Hone and Goad.)

Generic Windsweep build. For use in mixed earth blessings team to get the 754 score.

+Spd, -Res: literally everyone uses these IVs.
•Expiration, Dragonskin, Dual Rally: scoring purposes. Dark breath is optional if the team can spare a few points.
•Windsweep: it won’t proc on Amelia or other F!Grimas, or if chilled. But everything else gets chunked on PP, and foes die when countered on EP.
•Tactic: whatever works. She would preferably receive Atk and Spd Tactic from teammates.
•Guidance: to make up for lack of mobility.
