Robin (F)

This build exists solely for those who want to invest in Female Robin as a favourite and use her in more than just one mode. The Tactical Gale is nice if you play Aether Raids, but there's a whole game outside of it, and with the addition of the lifesaver that is the Madness Flask, Robin can finally break out of her niche and be more self sufficient as a unit.

The Madness Flask is great, giving Robin Fury 3, playing into her jack-of-all-trades statline, and with a Res refine, giving her respectable bulk to engage enemies both up close and from afar. It also helps salvage her lower attack and speed, so, with a little team support, she can go toe-to-toe with a wider array of units, or, use her newfound power to fight back against units with middling speed she once had as well. The HP loss allows her to capitalise on lower HP dependant effects to bring out the power.

Draw Back is just a reliable and handy skill for most ranged units, and can be substituted for anything you personally like.

Bonfire plays into Robin's higher Defence, and has a lower cooldown than her native Ignis, which can be kept if desired, or if you have a skill like Infantry/Ostia's pulse active on her.

Close Counter is very self explanatory, Robin has good Defence for a mage, and with this new weapon for her, her Res won't be too bad either, letting her counter melee enemies of all stripes as well as ranged ones, expanding her options in battle for how to use her.

Vantage has great Synergy with her weapon and Close Counter, letting her strike back with lower health first, able to get the drop on initiators, especially ones she's weakened from afar already. When her special is ready, Vantage can make for a deadly get out of jail free card when used in conjunction with it.

Attack Smoke is a simple skill, helping Robin's bulk and survivability by having her debuff enemies around her after attacking an enemy, which can be great if she's engaging multiple enemies at once and doing a bit of tanking. Her C-Slot is flexible, but Smokes tend to work nicely for Close Counter ranged units overall.

The Brazen Attack/Defence Seal is more or less perfect for Robin, but can be swapped for any Brazen seal in the game you personally prefer, this one simply exists to make her a stronger physical damage tank, give her solid attack, and strengthen the power of Bonfire. It activates in a similar range to Vantage, and her weapon effect means she can reach the HP threshold with greater ease.

Overall this build is there to get the most out of Robin's mixed stats with a weapon and setup that goes all in on it. This is more of a mixed phase/tankier setup for that particular playstyle, but can also be tweaked into an offensive one. Fury weapons can breathe new life into all kinds of units and open up greater possibilities for them, and Robin is a great example of that, going from a Raven Tome unit that only sees most of her use in Aether Raids, to a generalist who can be used in all kinds of PvE and PvP modes alike. Good for fans of the character like myself who enjoy using her.

The aim of this build is for people doing high merge and Dragonflower investment into Robin. Tactical Gale's support powers are great for mixed teams, which you may find yourself running in modes like Aether Raids, and the flat +4 buff to all four stats also helps units like her, jack-of-all trades types, mixed tanks, and more duelist type units. It's also handy in Grand Conquest maps as well if you like using a wide variety of movement types from your friends and the Raven tome power lets her easily clean up bow and dagger units, and initiate strongly onto staff units as well. Draw Back is fairly standard for mages, though Swap and Reposition can work depending on preferences. Bonfire works nicely off of her decent defence stat, and is quicker to activate than her native Ignis, though this is a matter of preference. Close Defence lets Robin tap into her defence stat to bait in and punish melee units, though red units may give her trouble and are some of the most prevalent melee threats, you can still use this to bait in lance and axe units with low resistance, largely playing on Robin's utility to weaken them or even secure a kill. Quick Riposte is how Robin secures her doubles as the speed ceiling ever increases, even at full merge and flowers her speed sits to an average, so this lets her use her decent defence to bait in units. Even Defence Wave was largely chosen due to how it's readily available from Silas, though now the Odd counterpart can be gotten from Haar, it's down to preference really, and helps give her the defensive push to tank with. Eventually when they make Joint Hone Defence that will be better for her. Finally the Attack Defence Bond Seal lets her remain close to allies she's buffed, and gives her some attack power and more defenses to better tank and punish with, however Attack Speed Bond can work as well at higher merge levels if you want a better chance warding off doubles or securing some of your own on the player phase. All in all Robin can be a decent ranged attacker, can deal with colourless units fairly well, handle some physical melee and buff up the as well. Decent all-rounder, useful moreso in PvE than PvP, but can be a helpful tagalong in Aether raids.

This set turns Robin into an offensive support

Robin's stats are very middling as she has barely enough to deal damage, prevent some doubles and taking hits. But with the help of the A skill and Seal, Robin's stats will turn to 57 Atk/ 36 Spd/ 29 Def/ 29 Res. This is very beneficial for Robin as now she's a threat to low res units and her newfound speed makes sure that a lot of units will have trouble doubling her which can prevent a lot of ORKOs.

Due to her middling bulk, Chill Atk is a good choice for Robin as it allows her to take on highly offensive Blue Mages and Colourless units such as Brave Lyn, Delthea, Linde etc. as their usually high Atk stat will be crippled by the Chill Atk.

C skills are flexible and up to preference. You can choose Atk Smoke to further compliment Chill Atk or you can choose Drive skills or double Spur skills. My personal choice is Close Guard as it supports the team in taking hits.

Due to how the set works, there is a good amount of specials to choose from. With Robin's 57 Atk, Draconic Aura and Glimmer can capitalize on the high Atk to deal devastating damage. With her Res being pushed to 29 when Brazen Atk/Res activates, Robin can also choose between Bonfire, Ignis, Iceberg and Glacies for her specials and these specials are useful if you're looking for consistent damage.

All out waifu-ism, this build is about reckless, single-minded pursuit of a Fire Emblem Avatar Main Character. S Summoner Support, S Ally Support (Cordelia in this case for maximum crack OTP sperg), and generous grail usage for +10 Merge. Ultimate Robin isn't so much about viability as it is about satisfaction over using a favorite character.

Gronnowl (+Res) is a favored alternative to the niche uses of Raven or Wolf builds and, unlike Blades, the boosts are applied across other stats to help shore up Robin's generalist statline. Ideally, Robin moves with an entourage at the edge of the danger zone. As long as she has at least one ally adjacent all the buffs come into play.

Reposition over Draw Back simply because her Ally Support is an extremely fragile Gale/Sweep Cordelia. Whatever works.

Native Ignis stays on as a great Special attack. It charges reliably and benefits from Robin's buffed Def stat. Aether is still an alternative, trading power for sustainability. I'm also curious about Blue Flame but don't have the data on whether the +25 damage exceeds a Def boosted Ignis.

Maximum bondage! Atk/Res Bond in the A Slot and Atk/Def Bond in the Seal Slot takes advantage of the fact that Gronnowl brings allies along for the ride anyway. Stacking the buffs from Weapon and Bonds offers a minimum +12Atk and +7Def/Res, with an additional +4 to each at full Owl power.

Quick Riposte ensures the doubles when Robin hits back following a successful bait. Coupled with the boosted attack this is usually a big deal. Her natural speed isn't dreadful, Gronnowl even helps as long as positioning is prioritized, but QR removes the gamble at least. I haven't gotten the fodder to try it out, but Mystic Boost and Null C-Disrupt also seem like interesting alternatives to explore.

Spur Def/Res is the love and compassion of the Twintailed Tactician. The build relies on sometimes selfless positioning of allies that puts them in danger so a boost to Def/Res is in order. It's small comfort in the larger scheme of things, but any little bit helps.

Ultimate Robin has bulky survivability. She was already a capable physical tank for a mage and possessed Res that could be easily patched up. With the proper support from her minions, Robin even survives initial encounters with both Sword and Red Mages offering respectable damage in exchange. She can overpower Blues and Greens, and contend with Colorless foes without being too concerned about reprisal attacks.

Extras. As mentioned, this build relies on positioning and supportive allies. Since they will usually be around Robin, all allies should run useful C slot abilities to further Robin's cause, I'm fond of Close Guard for example. Debuffs and stackable stats are lifesavers. A strong Blue that can clear the more stubborn Red units is desirable. A healer could help as well, especially when Robin tanks with her face too often.

Aight so Im just going to say upfront that this is a incredibly expensive build, however the rewards for this build are quite nice since it makes Robin *viable* making her a high damaging tank (sorta).
A Slot: Close Counter to make use of Robins defense stat against melee units.
B Slot: Def/Res Link was originally meant for support but since it allows infantry to be able to get +6 to 2 stats without a tactic team it was a nice coincidence and it's necessary for a blade tome.
C Slot: Spd Wave (Atk is also fine but you gotta fill the gap in her Spd) its just a nice added bonus for every turn since you wont need an ally to get it off. Seal: Darting Stance is added to close the gap in her Spd but that is my prefrence, especially since you could and probably should use quick riposte if youre not using SS but you have to keep her health up.
Special: Aether isnt necessary or even the best choice but if you have infantry rush it becomes quite viable for its healing and damage imo. With support from other units you can get all stats to +6 making her more threatening then Nino because Robin can take a hit, at the end of the day you would only do this if you like Robin way more then meta characters with nice skills (Karla, Nino, Winter Tharja and others lost their lives to this build) but Robin can one shot people so its probably worth it
