Hollow Palm: It should say explicitly that quaterstaff-specific nodes to not affect unarmed attacks

To me, saying you "attack as though using a quaterstaff" could be read to imply that any game features that check to see if you are using a quarter staff will function while using Hollow Palm. But the quarterstaff node clusters don't work while unarmed and using Hollow Palm. I suspect there are players who are unaware of this and select these nodes without realizing they aren't working for them.
