How does this work with his staff? He carved the spell on the end of his staff multiple times and used it against Asher in Skin Game. Harry is moving the staff, but the actual spell is not touching him directly (ie ring on skin). I could buy the argument that Harry is necessary for the rings to power up. We only saw the rings "being charged" while he was wearing them within his aura. The staff is a different story. The carved spell on the end of his staff is not within his aura. Is it charged by passive movement (just being used as a walking stick)? Does Harry have to run energy through his staff with movement to charge the spell? When it comes to the staff, it seems inefficient to have to actively run energy to it in order to charge it.
I think it would be the same as the rings, so long as he's manipulating the staff, it draws energy from him and stores it in the end of the staff.
My question would be, the 76 layers (iirc), do you nave to fill them one at a time, layer 1, then layer 2, etc. Or do you think they're filling simultaneously? I think that make it pretty strenuous just moving it around, at least until they were filled and no longer sapping the extra energy.
