[@Enkryption]: Mmm, a couple things here.

Harpy feathers are pretty ordinary feathers, so I'm not really sure how they'd be useable in that way. I know "shoot feathers as projectiles" isn't exactly uncommon but they're usually more inherently magical entities or the feathers have unique properties, harpies are in most respects in-universe "ordinary" in terms of their physical properties.

Also they're not really [i]beasts[/i] per say, aside from being less human(in their wings and legs and all that) then the non-monstrous races. They're actually one of the most commonplace monstrous races since they get employed as couriers.

My justification is Ninja-themed Wind Magic, as far as being able to fire the feathers. Basically, coating the feathers in magic, giving them a rigid form, and cutting edges. Beyond acting as a focus for the magic, they are just normal feathers, unless coated in herbal oils to give them debuffs on hit, like poison or torpor/slow.

I'm very curious, now, about if there would be something to playing her as a Courier, and having her basically serve as the messenger of the temple she learned her magic from in the first place. That would give her a pretty good sense of direction, lay of the land, and, potentially, polyglot skills, as she would find herself in foreign places to delivery and retrieve parcels.
