You use madness as a refuge from terrible truths about the world.
Benefit(s): You gain a minor insanity. As long as you are experiencing its effects, you gain a +2 bonus on concentration checks and on Will saving throws against mind-affecting effects, including saves against additional dread.
Note: Your GM chooses your insanity, but should work with you to ensure it will be an aid and not a hindrance in the group’s enjoyment of the game.
