staff vs specter

I swung my staff at a specter and hit it, and the ghostly warrior reacted as if struck by a heavy brick. It was a curious kind of impact-not the thudding thump of hitting something solid, but some kind of impact nonetheless. I knew from the way that the specters had come up through the earth that they were only partially material. A material impact would have little enough effect on them, and the strength of my arm behind the swing meant nothing to them. But the power of my will that I had called up and held ready in my staff-that was something else. That energy was what the specter reacted to, and I pressed my advantage, whipping my staff through the specter's head and belly on two separate swings, driving the apparition away with howls of pain.
