Either make Kuru less deadly, or make Prions harder to get.

[Don]

I'm adding a minimum reagent amount required for infection.

I'm also fixing the long-standing thing that Don just mentioned. Unless we aren't thinking about the same thing.

Yes, that was it.

I think there's another thing too that might be worth locking down. Enable PMs for me or just check the PGS thread if you're on SA. It's the first part of SageAcrin random obscura questions on page 69. You can presumably just do that thing and extract, rinse and repeat with no risk of self infection.
