Dexter turned his head in though. "Hmm? This town is pretty big you could probably find some. I would check a potion shop, or any other place that sells oils for weapons." The oil that Dexter was talking about was in fact meant to be use on swords. It would give the swords a temporary effect of ghost touch allowing the weapon to be used effectively for slaying incorporeal creatures. He had no idea why Ellen wanted it. It seemed odd that she would need an item for slaying ghosts, but he didn't question it.
