Help me figure out what to do with her.

I mean... the only other "highly recommended" build is probably her Quad build. Brave Bow + Swift Sparrow + Spd Smoke, although that's usually with utilizing a speed boon.

Any other build is probably more "creative" in terms of what she can do, like using her Cupid Arrow to make her a support unit.

Brave bow is the other one you'll see often; less conventional stuff can include slaying + desperation + moonbow or fishie bow + guard or breaker + flashing blade
