I’m not sure that there are no patterns in what works for self-taught architects, and if we were aiming to balance cost & likelihood of impossibility then I might look into that more (since I expect A,L,N to be the the cheapest options with a chance to work), but since we’re prioritizing impossibility I’ll stick with the architects with the competent mentors.

I find a pattern in that buildings using Dreams together with either Wood or Silver have an 80% chance of being Impossible when made by a Self-Taught architect, but honestly this seems irrelevant since the other two types of background are a 100% guarantee so they’re better value for money anyway.

This is true, but ’80%′ here means only ^{16}⁄_{20}. A result this extreme is theoretically p=0.005 to show up out of 20 coin flips...if you treat it as one-tailed, and ignore the fact that you’ve cherry-picked two specific material-pair options out of 21. Overall, I’d be very surprised if this wasn’t simply randomness.

I admit it’s cheating a bit the spirit of the challenge, but in practice, I guess it’s the round amount that makes me suspicious that it might be intentional. But it’s true there doesn’t seem to be a broader materials related pattern, so it may just be as you say.

I got the same result: DEHK.
