|This build targets a niche that's very rare in Fire Emblem Heroes: reliable, safe Galeforce procs. Utilizing her robust offensive stats and intense speed, Cordelia not only kills the large majority of the entire roster (including greens), but does so while taking no damage, and being incredibly resilient due to her high speed, should she need to take an attack. The power of the build scales even further when complemented with a dancer, allowing her to kill three targets in a turn, regardless of if the targets die in 1 or 2 hits.
It's essential to note that this build generally requires Cordelia to be buffed with '"`UNIQ--item-486--QINU`"' and '"`UNIQ--item-489--QINU`"' to achieve the best spread of matchup results, which means that you must have obtained Hinoka at some point.
'"`UNIQ--item-492--QINU`"' grants her a large boost in Atk compared to '"`UNIQ--item-495--QINU`"', giving her reliable access to '"`UNIQ--item-498--QINU`"', while enabling her to more recklessly attack into otherwise suboptimal matchups. It's incredibly important to note that '"`UNIQ--item-501--QINU`"' requires enough Spd to double a target to generate value over '"`UNIQ--item-504--QINU`"', and is generally countered by '"`UNIQ--item-507--QINU`"' and '"`UNIQ--item-510--QINU`"'. This can, of course, be countered by running a matching breaker of your own.
'"`UNIQ--item-513--QINU`"' is incredibly powerful and versatile for flier teams. Cordelia is no exception. Aggressive plays, retreating, abusing terrain, '"`UNIQ--item-516--QINU`"' enables it all. Otherwise, if you're hunting for arena score, a double rally is the way to go, although it's completely redundant for the comp via '"`UNIQ--item-519--QINU`"'+'"`UNIQ--item-522--QINU`"'
'"`UNIQ--item-525--QINU`"' is the centerpiece of the build, enabling Cordelia to tear through entire armies. Paired with a dancer, she can eliminate 3 people in arena a turn. Offers the max arena score as well.
'"`UNIQ--item-528--QINU`"' is the engine that drives this build, giving her increased Special cooldown per attack to help her activate '"`UNIQ--item-531--QINU`"'.
Her B slot is largely flexible, and should be carefully adjusted to adapt to the meta. She can generally equip '"`UNIQ--item-534--QINU`"' as a catch-all, but there are certain alternatives currently. For example, Reinhardt is a prevalent meta pick in arena, who typically offers Cordelia a guaranteed Galeforce proc. A certain subset of Reinhardt players run him with '"`UNIQ--item-537--QINU`"', which means that '"`UNIQ--item-540--QINU`"' is actually a pretty reasonable choice to continue to secure her galeforce procs against a common enemy.
'"`UNIQ--item-543--QINU`"' is an incredibly fun choice in non-Arena content.
'"`UNIQ--item-546--QINU`"' and '"`UNIQ--item-549--QINU`"' are typically lackluster for this build. It's an aggressive playstyle that wants as much forward momentum as possible to snipe key targets. If you aren't yet comfortable with player phase flier teams, it's a decent choice to serve as training wheels, but you'll find yourself caught in some matchups running it.
On a flier team with Corrin (F) (Nohrian Summer) or Camilla (Spring Festival), she'll need to run '"`UNIQ--item-552--QINU`"' to enable the bladetome wielders to reach their maximum nuke potential (Cordelia and the Bladetome both desire Hone, and the Bladetome desires Hone+Fort). Otherwise, depending on the composition of your flier team, '"`UNIQ--item-555--QINU`"' and '"`UNIQ--item-558--QINU`"' are perfectly fine.
It's essential when running this build that you deliberately plan the order in which you attack enemies, as well as who you attack and what they have equipped. For example, against a team with Lyn (Brave Heroes) and Reinhardt, Reinhardt requires 2 hits to kill, while Lyn often requires one. This means that the correct move to generate maximum value for your team is to attack Reinhardt first to activate galeforce, followed up by finishing Lyn. Squishy reds should also be avoided as primary targets as well, for the same reason. Also note that Cordelia can eliminate many greens, as well, and can even springboard off of tanky greens to access her preferred target behind them.
To this end, it's also important that matchup stats are carefully calculated. There are situations where the correct choice is actually to avoid honing or goading Cordelia, to ensure that she doesn't kill the target in one hit.
While being able to chip targets you'd otherwise normally have to avoid is powerful, it's important that you note the build of the person you're going to chip. For example, if you're attacking a Hector who's running '"`UNIQ--item-561--QINU`"' and '"`UNIQ--item-564--QINU`"' or '"`UNIQ--item-567--QINU`"', you can accidentally create a situation where Hector gains lethal on somebody who he otherwise wouldn't have if you chipped with another unit first, and finished with Cordelia.
Lastly, on weeks where dancers are available as bonus, this build kicks into overdrive, as dancers allow this build to activate galeforce no matter who they hit first. Enjoy!
