Saw a few movies and thought of this trait for pathfinder
Obsessive Compulsive Fanaticism- Mental Trait-Your character is obsessed with a single interest. This can range from a love of Gothic architecture to goblin language verb conjugation. On any knowledge roll that is closely related to your interest, you gain a +5 bonus to the roll. However, whenever an object of your obsession is nearby and you are not actively working with or discussing it, you take a -2 penalty to all skill rolls.
