This has a few bugs, so I thought I'd mention them :
-Infernal Power and Divine Power have checks for not having the opposite realm books. However, this is located in the single-pick branch of the code. As these are double pick retorts starting from 1.31, I assume this code never takes effect.
-Nature, Chaos and Sorcery mastery, as well as any other retorts with books requirements ignore those.
-Famous grants +10 fame when found, but it's also located in the single-pick branch and yes it also has been changed to cost 2 picks in 1.31 so this will most likely not activate either.
