Notes
Garcia is an interesting character whose kit revolves around building her trait stacks each turn, which make her grow stronger over time. As such, putting the Devil tarot on her makes by far the most sense, as you’ll see her go from just okay to a competent nuker by the end of a battle (as long as it’s sufficiently long, which most difficult content is).
Ideally, the way you would use her on a perfect turn would be to (starting with 4 or 5 NRG), use her Taste of Blood skill, then grab a heavily-damaged enemy with Spinning Blade, which would then kill that enemy, thus restoring 2 NRG, and then go use Execution Time on another enemy (if you can get a kill with this, she gets an extra stack of her trait). Obviously, this isn’t going to happen every turn, but that’s the idea of the kit (or at least the build I’m suggesting).
Just be aware that her trait stacks can be removed by enemy buff-removal effects, which means she struggles in levels where that’s common.
Other than that, she’s a pretty straightforward DPS. Just remember that she has that Taste of Blood skill, so if you need to heal or cleanse some debuffs or anticipate that need, save that skill for that.
When rolling stats, aim for P.ATK.
