Possible nerf to put Ahri in line with other mages (and their q skill shots)
I'm not sure why Ahri doesn't have this already, her Q doing reduced dmg the more targets it hits, down to a minimum of 40% (like the likes of Orianna/Cait/Varus) It could recalculate to 100% on return of the orb but should still do reduced dmg to subsequent targets.
Same goes for TF Q tbh, not sure why he doesn't have it yet.
