Legendary Robin (F)

• Preferred IV: +ATK or +SPD / -HP
• Weapon: Expiration 
• Assist: Reposition / Draw Back
• Special: Moonbow / Bonfire / Noontime
• Passive A: Dragonskin
• Passive B: Quick Riposte / Guard
• Passive C: Res Smoke / Atk Smoke / Goad Fliers
• Sacred Seal: Distant Def / Quick Riposte

The first flying unit in the game with an innate Distant Counter Prf, Legendary Robin's most powerful niche is taking full advantage of her weapon and acting as a dedicated counter to ranged units on a flier team. In addition to her Prf, she also holds an exclusive 300 SP A slot skill, Dragonskin, which contains both the effects of Iote's Shield and the unreleased skill Bracing Stance. This not only eliminates her weakness to archers but grants her a bonus 4 Defense and 4 Resistance whenever she is attacked, both traits that are phenomenal for accomplishing her goal a flying ranged tank.

Reposition and Draw Back are the classic assist picks for flier units, who can easily travel around the map.

Moonbow is fantastic for Robin as it should activate every time she is attacked and helps make up for her slightly below average Attack. This helps to ensure she achieves her kills without accidentally leaving an enemy alive at very low HP, which would allow them to make use of skills like Vantage or an allied Wings of Mercy. Bonfire, which Robin already has by default, is a great alternative that will instead proc every combat she is doubled or instead be charged and ready for her to make use of on her next Player Phase. If Robin is receiving consistent Hone Flier buffs, then Bonfire will give her the most nuking power.

It is important to note here that compared to most Enemy Phase dragon units, Legendary Robin is not quite as strong a user of Aether. This is largely a result of her lack of access to cooldown accelerating skills such as Steady and Warding Breath. While she can wield Heavy Blade, she does not have the Attack stat to activate it consistently. This means she would rather stick to lower-cooldown Specials with a charge no higher than 3. Of course, those aiming for high Arena scores won't have much of a choice, as breath users are unable to use Galeforce, the only other 500 SP Special. If one still wants their Legendary Robin to have some form of sustain, particularly for PvE content such as Tempest Trials, Noontime will grant her a welcome heal on every combat, though the lack of burst damage may make it unreliable in Arena.

Quick Riposte is key to Legendary Robin's effectiveness, as she will often require two hits to ensure a KO. It will also allow her to combat even the fastest of enemies that she wouldn't be able to double naturally. While usage of the skill is important, it can be equipped either through the B slot or as a Sacred Seal. If chosen as a B slot, this grants Robin the ability to equip the Distant Def Sacred Seal, which together with Dragonskin results in a boost of 10 Defense & Resistance when attacked at a range. If Quick Riposte is instead used as a Seal, then Robin can make use of the B skill Guard, which can keep her significantly safer from units such as Ayra, Reinhardt, and Bold Fighter users who deal heavy burst damage thanks to their quick Special activations.

Robin's default C skill, Res Smoke, is great for granting Robin some welcome extra damage over repeated engagements. Atk Smoke is a similar alternative if one wants to instead prioritize her tanking power. She may also find it most useful to utilize a flier-synergistic skill such as Goad Fliers, which more directly boosts up her team.

• Preferred IV:  +SPD or +ATK / -HP
• Weapon: Expiration / Lightning Breath+ (+Spd)
• Assist: Reposition / Draw Back
• Special: Moonbow
• Passive A: Fury / Swift Sparrow / Dragonskin
• Passive B: Quick Riposte / Desperation / Hit and Run
• Passive C: Res Smoke / Atk Smoke  
• Sacred Seal: Speed +3 / Guidance

A somewhat gimmicky set that aims to abuse Legendary Robin's nice offensive spread of 32/35 Atk/Spd to act as a more conventional offensive flier. Generally, this build starts off nearly the same as the previous build, using it as a base and then slowly making changes until the user finds themselves with a comfortable amount of Player Phase Speed.

One of the first changes made is that a +SPD IV is prioritized, already setting her to 38 Speed. Next, her A slot can be switched from Dragonskin to Fury, granting her a +3 boost to all stats, putting Robin at 41 Speed. Swift Sparrow works as a more expensive alternative to Fury, though does nothing for her Enemy Phase. Continuing the pattern, a Speed +3 Sacred Seal will push this to 44 Speed. 

If one truly wants to push this as far as it can go, her weapon Expiration can be replaced with a refined Lightning Breath+ (+Spd), which is effectively a trade-off of 4 Attack and no Special cooldown penalty for an additional 3 Speed and 5 HP, putting her at a grand 47 Speed. If she is then able to benefit from the effect of an allied Hone Fliers or Hone Dragons, it even hits an absurd 53. Reaching this high will likely be overkill, so some of the Speed boosts can be reverted back based on preference, such as sticking with Expiration, re-equipping Dragonskin, or using a different Sacred Seal.

Quick Riposte starts out as her base B slot option, making sure that she can always perform doubles on Enemy Phase, though if her Speed is invested into significantly, the skill eventually starts to lose its value. Desperation is a good alternative that works well at such high Speed, letting her continue the fight even after her HP starts to dwindle. Hit and Run can also work, moving Robin to a safer position after attacking, and mimicking the in-and-out play style of other offensive fliers, such as Cordelia.

Res Smoke and Atk Smoke remain solid options for her C slot, debuffing enemies around her, a useful tool for a unit such as Legendary Robin who is likely to engage in multiple successive combats.

While it doesn't directly boost her own power, as a flier Legendary Robin can also make use of the Guidance seal when used off of a flier team, helping ferry around any armored and infantry allies.
