Corrin (F)

IVs: +Spd -Res

With the introduction of Steady Breath, Corrin finally has a way to circumvent her biggest weakness compared to other dragons: her low attack stat. By using Steady Breath, Corrin is able to increase her bulk and fire off quick specials even with LightningBreath, making her a unique threat as a fast dragon.

With a solid 41/34/18 (assuming given IVs), Corrin has great physical bulk and passable one time magical bulk. Combined with her great 37 speed with +Spd denying many doubles from her opponents and potentially securing some even without Quick Riposte, Corrin is able to take a lot of punishment from physical units, but should stay clear of mages when possible.

To capitalize on this and Steady Breath's effect, Quick Riposte is used to secure quick doubles whenever she is attacked. Assuming she is attacked and is not doubled while having QR, with Bonfire at a 4 cd due to Lightning Breath combined with Steady Breath charging 2 cd per attack in an engagement, Corrin can now fire off a Bonfire for every time she defends, adding an extra true 18 damage to each counterattack she has, allowing her to now more readily secure kos against her assailants, especially combined with the Attack +3 Seal.

Her Support Skill is flexible, as is her C Slot. There are several options for Corrin to run though, including Threaten Res to help with her damage output, or Swordbreaker to deal with Falchion users. It should be noted however, that outside of a +Spd Fury Lucina, none of the Falchion users are actually able to double +Spd Corrin, allowing her to win in a 1v1 situation when defending thanks to Quick Riposte. Renewal can also be run should one wish to maintain her bulk, and is a valid option given +Spd Corrin's already decently high speed of 37, but this will reduce the amount of kos she gets when defending significantly.

With weapon refinery, Corrin's offense becomes much more potent, compensating somewhat for her low attack. She can opt for a +3 spd or +4 def boost, though given Corrin's already lackluster attack and workable speed, she can make generally more consistent use of the +3 MT boost that is available, making her defensive damage more reliable.

Fury+Vantage to kill units with Lightning breath, Sacred Cowl and Deflect Magic to survive those hits from Reinhardt and his sister, and Threaten Res to make sure you kill the enemy.

And if you're insane like me, make numerous 3/4 star Corrins into 5 stars and merge them for maximum effect.

This is an enemy phase Corrin who can tank hits with her good speed and defense. She can beat low res units with spd from 30-38 thanks to quick riposte and with triangle adept she can tank swords and some of the slower red mages. If you want her to have a better time with mages give her lightning breath and moonbow with the distant defense sacred seal to patch up her poor res.

This build makes F Corrin function very similar to Camus, though without the high movement, and uses magic instead. She'll be fast enough to avoid getting doubled by popular glass cannon characters and tanky enough to survive hits from hard hitting physical units. And with the proper abuse of fortresses, she can even deal with green units like Hector.

Low Hp and Fury puts her in range for Vantage really fast. Bonfire takes advantage of her Def, though it will be at a 4 counter, so Moonblow can be subbed out for slightly more frequent triggering but much less payoff.

She was one of my first 5 stars, so the build isn't quite the best but it does what I needed back when I started playing - tanking and killing Ryoma/Xander/Ike...
