I think I whooped with a terrible kind of glee as I brought the grenade-pistol up again and continued pumping round after round into the invisible barrier in front of the kahuna until the weapon clicked empty. The shaman caught on quickly to what I was doing. A witch-wind whipped up out of nowhere, lashing across the jagged rocks. But smoke grenades don't just burst in a cloud of smoke and that's it. No, they continue to pour the stuff out for some few seconds after they've detonated. The shaman's tame wind might blow away the smoke that was already there, but half a dozen grenades were lying on the ground between him and me, still gouting great viscous clouds of the stuff.
