Man, I’ve had astonishingly bad luck trying to get the Purest Saint achievement.
First time I went that direction, I was going in blind, and hadn’t bought the glamour potion because my glamour was already pretty good.
Second time, I had all the potions, but my negation skill was pretty bad, and ended up not having enough to actually make the potion. Doh.
Third time, I got the fateshaper in chapter 3 and set it to black mage to make sure I had enough negation. You can guess where this is going - despite not really doing anything with negation beyond that, I got sent down the negation climax instead of the glamour climax. (That’s how I got exiled for destroying the palace with negation magic that I barely touched.)
It’s fun, though. I’m very much an optimizer, and your games make it satisfyingly complex to optimize.
edit: What on earth? I just tried a fourth time, and got…no climax at all? I didn’t even think that was possible…
edit2: aaaah, working on a rot cure during peace prevents the glamour climax. Is that intended? You’ve got at least one line (6275 in war.txt) that can’t happen because of that.
edit3: And finally I realize the purest saint achievement isn’t from developing a cure for rot while a saint at all. It’s from getting the miter while remaining a saint. Oh well.
