[@Scio] The more complex the thing, the longer it'll take to do? And possibly take up more energy and thus keep him down for longer if he tries to do it a lot? More descriptive language is used by humans to explain concepts that we don't really get instantly. Like, if we want water, we can just say it's water that's wet and cold and we know it's water and stuff. But for, say, a beam of light, you need to also establish how bright it is, what colour it is, et cetera.
