And Dokku would be able to sense and react to the spells as multiple Force Users light and dark side have reacted to things they can't see or moving so fast they shouldn't be able to respond in time.

And some spells just can't be blocked. He would have no way to stop himself from being turned into a rat. Or even just imperio
