The accident scroll is particularly useful in Oligarchs case because of the citizen militia.
Making Citizen militia less important or not summon able by the ruler could also solve this.
I think what we see here is half of the islands magic focused on one character because of the citizen militia.
I experienced just this very thing on Belluaterra. Dominorum got wiped out for it. A little annoying and frustrating, but I did consider it a clever tactic.
Perhaps the trick is too powerful and needs to be nerfed somewhat, but I do personally enjoy having magic in the game overall.
