Atk+ Spd- Elencia

Yes, any Elincia with +Att is amazing! She's gonna sacrifice some of her quad attacking abilities, but with her weapon and death blow, she'll be able to ORKO most units in player phase anyways. The only detrimental bane for her is -att imo.

Yes, she's "usable" (coughmassiveunderstatement).
I keep answering to these threads that think she's absolutely screwed. While -Spd is arguably her worse bane, she's far from unsalvagable, let alone unusable. If even at keeping her with her basic Death Blow (which is what I'm doing, also -Spd). She can still reach 36-37 Spd with L&D (which massively synergises with Desperation) and she gets ridiculous bonuses at Trials.

Since I don't have L&D fodder at the moment, I'm keeping her with Death Blow and gave her Moonbow and Quickened Pulse. It's actually kind of silly and the easiest fix for units with high Atk.

She is the most broken hero for red even with -atk she would be usefull as a Brave Hero.

Unless you're hell-bent on Quadding, a +Atk Elincia is literally Cherche-tier good. Keep Death Blow on her, and watch as she tears through any non-blue/bulky red in her path

I got -spd +def I would kill for +atk.
Quickened pulse and moonbow. Honestly...attack boon on a brave hero "is she usable"...
