I phrased that very poorly. Not so much the lightning itself having prolonged contact, but a storm in which lightning is present having prolonged contact. Think of it like saturation; if enough lightning strikes in a short enough time, an Ashphol forms. And yes, the body could be manipulated by magic users. But it's not like obviously made entirely of lightning; they have a basic humanoid form. Feel free to shoot this all down if you're not a fan.
