Inherited Madness

Prerequisite(s): Tantalus bloodline

You gain an insanity of the GM’s choice (see Madness). 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 Constitution saving throws to concentrate on spells and on all Wisdom saving throws. If your insanity is cured, you may either gain a different insanity or choose a new feat in place of this one.

Anyone using detect thoughts or other magic to hear your thoughts must make a Wisdom save (DC 8 + your proficiency bonus + your Charisma modifier) or suffer from a randomly determined short term madness.
