Kenobi reached the top of the stairs and a single slash of his lightsaber dismantled both droids. Before their pieces could even hit the floor Dooku was in motion, landing a spinning side-stamp that folded Skywalker in half; he used his last burst of dark power to continue his spin into a blindingly fast wheel-kick that brought his heel against the point of Kenobi's chin with a crack like the report of a huge-bore slugthrower, knocking the Jedi Master back down the stairs. Sounded like he'd broken his neck.
