A predictable spread of danger seems more interesting than every lesson having the same potential for a serious disaster. This is effectively just a spell of “trigger a RNY/UNE disaster in any class, and get a Grudge and an F”.

That’s not entirely fair. It still requires high BST and LAT, and a C in UNE, and decrements your grades in these Subjects as well, so it’s quite an investment for a reversible effect. If all Students flock towards the same Lesson and set themselves up for zombification, that’s their problem. Personally, I’d be more worried about the DIV disaster being chain-triggered in a full classroom.

That it’s “reversible” isn’t any consolation - anyone investing in this spell is likely to Disrupt the relevant lesson immediately. And a game mechanic of “if too many students attend the same lesson, they may all get zombified, that’s their problem” is just going to quieten the game down, and disadvantage players who check the blog less frequently (and have no choice but to join an already-busy lesson).

As much as I liked the idea at first Kevan is very persuasive.

I don’t much care for spells that let you edit the ruleset in any fashion.
