Bridal Cordelia

Merged +2 and Summoner Support. Player phase nuke, coupled with a Hone Atk dancer clears whole stages, tempest trials, and chain challenges without breaking a sweat.

This is B!Cordelia's exclusive player phase kit.

A +Spd is ideal if running Cancel Affinity and +Atk if running a Breaker skill for her B slot. If you're running L&D you honestly shouldn't be concerned with your bane too much.

Firesweep Bow allows her to attack without fear of retaliation unless she fails to ORKO her opponent. L&D serves to bolster her offenses while Cancel Affinity lets her effectively combat pesky Raven tome users. If your team has trouble handling a specific unit, B!Cordelia has the niche of being able to run whatever Breaker skill she wants due to being a colorless unit.

Whenever she isn't attacking she can act as support by buffing with her inherent Rally Atk/Spd assist. Fortify Def complements her default assist, and works quite well the Fortify Res Sacred Seal. You can also opt to run a positioning assist skill such as Draw Back with Threaten Def as her C skill.

Her special is ideally a 3 turn cooldown special which can be Luna (+Spd) or Draconic Aura (+Atk) depending on her boon. This is largely due to the fact that her cooldown has a static decrease property thanks to Firesweep Bow (meaning her cooldown will only decrease when she initiates, because if she is initiated upon, she will die). To put her special activation into perspective I've listed below the possible attack patterns Cordelia will have in 2 initiations:

1st initiation: Cordelia Attacks > Cordelia Doubles / 2nd initiation: Cordelia Attacks > Special Triggers

1st initiation : Cordelia Attacks / 2nd initiation: Cordelia Attacks > Cordelia Doubles; here her Special is ready to activate upon her next initiation

1st initiation: Cordelia Attacks / 2nd initiation: Cordelia Attacks ; here Cordelia fails to double twice and leaves her Special Cooldown at 1 allowing her to trigger it upon her next double attack.

Utilizing a Brave weapon build, BC can KO nearly any unit. While there are some matchups that can cause concern, most of the time they can be easily played around.

Life and Death gives a massive boost to your attack power, offsetting the speed reduction and low might from Brave Bow+. This leaves you with Cordelia's base speed stat, which unless you're running a negative speed nature will be quite high. This allows you to double most of the units that have distributed their stats towards armor and health, allowing them to withstand your first onslaught.

If you just have the two aforementioned skills, Cordelia becomes one of the most formidable units in the game, but we're not done yet because as her A passive suggests, she provides both healing and nuking.

Breath of Life is what I prefer for her C passive. Ally buffs are cool, and running a defensive buff to improve ally speed, def, or res as they peel for Cordelia can be helpful, but rarely game changing and requires even more effort to be placed on Cordelias positioning. Breath of Life allows you to use your tanks in a more aggressive manner, baiting one or two enemies into killing range of Cordelia, who quickly dispatches them, healing the tank for 7 or 10 points, depending on whether you're also using the breath of life seal (which I recommend). Having a dancer or singer nearby allows Cordelia to potentially double the amount of healing done, providing 14 or 20 points of healing, easily outclassing the damage mitigation that a def or res buff could provide.

In my opinion, Cordelia's B passive is her most flexible. It's not that it's unimportant, as it can be used to give her even more favorable matchups, it is just very situational, since most of the time Cordelia KO's without it. Desperation is the most useful combat related skill, allowing Cordelia to take on mages with a high defense stat. It also allows her to come out favorable in certain (but not all) Hector matches. Lancebreaker allows you to KO Effie by nullifying her Wary Fighter advantage. Swordbreaker and Axebreaker both just guarantee the 4x hit, but you generally don't need it against the units that are speedy enough for this to apply to. Vantage can be used in select matchups against ranged units, but requires significantly more planning because Cordelia doesn't have the defenses to survive a miscalculated engagement and doesn't get a double attack from Brave Bow+ when defending either.

If you're satisfied with Cordelia's KO capability, you can try giving her a movement passive, such as Wings of Mercy, allowing her to jump long distances and KO an enemy. However, I've found this is rarely as useful as is sounds since your tanks and support unit should be positioned near Cordelia and are likely equipped with a movement support skill to get Cordelia either to safety or into a position to eliminate danger.

The most important part about playing with BC is that you give her a team that enables her to shine. I've found the following formula to be very effective:
>Two Tanks - I prefer tanks that have enough defenses to avoid getting KO'd any unit who doesn't have weapon or color advantage on them. Keep the color advantage different for each tank. This will allow you a tank for every situation. I like dual dragonstone tanks (Ninian and Young Tiki), because BC can easily KO all the Falchion users and I prefer to have BC be my only source of physical damage.
>Support Unit - I like a mage for this role. Basically this is BC's intern, and just follows after her to provide buffs, Drag Back or Reposition or magical damage to quickly dispatch the handful of foes that are so stacked on def and hp that they could survive a round with BC. I currently have a Nino filling this role.

Even though she got bad boon & bane. she's still decently reliable and surpassed my Klein in speed and my waifu material before Selena. afterall, i'm only F2P

This build includes the stats of a Summoner S support rating. With this build, Cordelia can OHKO almost any unit in the game as well as kill an unmerged Hector without Desperation.

Brave Bow+ allows for Cordelia to attack most units four times, almost guaranteeing death.

Reciprocal Aid allows for Cordelia to get into the HP threshold of Desperation without tanking a hit. A Cordelia with 40 HP can opt for Ardent Sacrificed instead.

Luna is guaranteed to trigger on a quad attack and allows her to kill even the tankiest of units.

Life And Death 3 boosts her attack into extremely high ranges as well as boost her speed to levels where she can quad most units.

Desperation 3 allows her to attack threats safely when she quads without having to worry about a counterattack.

Threaten Spd 3 allows her to quad even more units.

Cordelia really benefits from a support unit, especially dancers. Giving her a +Spd seal allows her to quad even more units.
