===Special Rules===
* Sanity is rolled instead of Resolve + Composure to resist the effects of Derangements.
* A character who passes a degeneration check may still earn a temporary Derangement: after the sin check, the player rolls his character's Sanity. On a failure, the character gains a Derangement; this Derangement remains until the end of the story, or until the character receives psychotherapy.

==Mythos==

Mythos represents (incomplete, pathetic, fallible) understanding of the Cthulhu Mythos. Such knowledge is dangerous, granting eldritch and unknowable insights and powers. The Mythos insinuates itself into the mind and body of investigator who learns too much, warping them.

Mechanically, it is a "power stat", like Gnosis for Mages and Blood Potency for Vampires, and therefore is treated as such when, for example, resisting supernatural powers. 

===Special Rules===
* Mythos starts at zero (unlike other power stats).
* It may ''only'' be raised by Mythos Experience Points (Mythos XP).
* A character may add his rating in Mythos to any Mental Skill roll relating to the Cthulhu Mythos. (For example, a character with Intelligence 3, Academics 2 and Mythos 2 would roll Intelligence + Academics (five dice) for generic research, but Intelligence + Academics + Mythos (seven dice) for Mythos-related research.)
* A character's maximum Sanity is equal to 10 minus his Mythos rating. Should a character's Sanity be greater than this maximum after an increase of the Mythos trait, the character loses a dot of Sanity and must check for a derangement as if he had automatically failed a degeneration check.

==Mythos Experience Points==

Mythos Experience Points (Mythos XP) is gained by investigating the Cthulhu Mythos. (Generally, this leads to Sanity sins.)

A character may spend Mythos XP to raise his Mythos trait.
