Rotation would only help  sphere if it produces a gyroscopic affect. It won't help velocity or impact. It will just make it ore accurate. My point about it doing limited damage was more that it probably won't be going as fast as say, an arrow, let alone a bullet, and that it has no edge or significant point. Penetrating a target's exterior could prove tricky.

Depending on how much Dust she uses, and what kind, they could do some damage. Not all Grimm are created equal, some are quite fragile.

I've seen many a staff weapon, though you just showed tree branches, and there are a number of ways to do it.
