-Get a scientist
-Get a Book of Secrets and throw it in the Core, which has become blue now (if you want to learn more on The Core check the Discord server)
-Sacrifice the scientist in the Core, you have a 50% possibility to get a "Warped" scientist and the achievement too, if you are not lucky, the Core will stay blue and you can sacrifice another scientist and hope for the best. This can be repeated infinite times until you'll hopefully get your "Warped" scientist.
