Exactly. I'm all for erratic magic causing mayhem because that will make it illegal, but 95% of players are wimps and having a risk of death attached to most scrolls will make them unwilling to use them.
Well, sure, if the risk is death...
Doesn't need to be that extreme. Hordes spawning in a different region, banishment scrolls summoning more daimons, healing scrolls wounding a random noble, etc. The risk of a mishap doesn't even need to be huge, imo, to be dissuasive on the realm-level, without also making them unappealing to the individuals.
