Neutral Ayra Question

With Slaying Edge + Wrath and high Spd, she'll be able to proc 2 Regnal Astra in a single round of combat against most units. That is an additional 43(0.4) = 17 from her Special and 10 from Wrath, giving 27 extra damage per proc. Proccing twice means 54 damage just from Special triggers, enough to take out almost every single unit in the game, even through Weapon Triangle disadvantage, except for someone like Zephiel and Arden who have ridiculously high HP. (There's a reason why she's considered the best Infantry Sword in the game.) DC allows her to pull this off in both phases, and her good Def means she can take some hits and fire back hard.

Personally, I wouldn't do it if I were you unless you plan to include her in your Arena team, which isn't feasible for higher Tier play (to be honest) unless you can get a lot of merges on her. I also have an Ayra, but with better IVs (+Atk / -Res), yet I stick to her default kit because I can't realistically merge her without insane luck (or whaling). Neutral spread is amazing, so she can run the default set without any problems. It still works pretty well from my experience, so don't feel like you have to pump maximum investment into her.

Hey! As u told before, Ayra shines more with the DC build. Why? Because she can proc TWICE Regnal Astra in one turn. And yes, the most OP skill she has ( i think that is the BEST ) is her special: 40% of her fking amazing speed with ONLY 2 cooldowns (so at least 16 extra damages, and as i said u can activates twice = 32 minimum damages WITHOUT the basic attacks) . If u compare with the similar specials which applied with other stats: bonfire needs 3 cooldowns to apply 50 % of Def ( only 10 % more). Thats why the Dc build is often quoted as the most powerful kit.
Unfortunately i dont have DC and wrath fodder yet
And sorry if my english is bad to be understood : im a french guy u know ;p

I personally don't think that DC is ever worth putting on a unit that you don't use much. Her slaying edge set is slightly better than her standard set but unless you plan to use her a lot or you have her merged a lot and use her for arena, then building her optimally will likely be a waste of resources

I certainly think so. With it, she can kill a good number of units she wouldn't be able to otherwise. With this enemy phase build, when they attack, it will not only proc Regnal Astra for her attack, but also likely trigger Wrath which usually kills them.

As someone who's used this build on her for quite awhile, even I'm still surprised by the amount of things she can kill. Assuming your's has 40 speed (which can be achieved with a speed refine from Slaying Edge) and wrath is active, Ayra can do 27 more damage than she would have with Regnal Astra, which allows her to kill even tanky blues! I'd definitely recommend building it.

If you're still concerned about the results, you could always check out a damage calculator to see if the benefits of a DC Ayra build outweigh the costs.

I used a -SPD/+HP Ayra to great effect with the Slaying DC build. She still killed most units in one round of combat (exceptions being Wary Fighter units and tanky blues).
Ayra can tank basically any unit that's not a blue running Brave weapon or Bold Fighter.

Regnal astra is a game-breaker. She KOs so many blues with it, it's kind of disgusting.
