Boon: Insulating Insanity You seek refuge from terrible truths by isolating parts of your mind. You gain an insanity of the GM’s choice (see Dread and Insanity in Chapter 4). Your GM should work with you to ensure its nature makes the game more fun for you and the group, and it should generally fall into the category of a first-degree insanity. As long as you have this insanity, you have advantage on Sanity Checks and Sanity saving throws. If your insanity is cured, you may either gain a different insanity or choose a new feat in place of this one
