Everything

Even without employing your Arts, you have a preternat­ ural gift for seeing things as they are, not as they appear to be. Illusions, disguises, cloaking spells, and other forms of trickery rarely deceive your eyes.

In game terms, you can make a Perception + Awareness roll to see through metaphysical deception powers: vampiric Disciplines, faerie cantrips, werecreature Gifts, Sphere-based illusions, and other powers that are based on deceiving a wit­ nesses’ perceptions. This roll works only against powers that deceive the target’s perceptions, not against any other form of Gift, Discipline, cantrip, and so forth. (Vampiric Obfuscate, for example, but not Presence or Dominate.)

The difficulty for that roll is generally 5 + the highest Sphere Rank or other level involved in that power; a Forces 2 /Prime 2 illusion, then, would be difficulty 7, while a vampire’s Mask of a Thousand Faces (Obfuscate 3) would be difficulty 8. If a character could normally get a roll to see through the illusion (as shown in How Do You DO That?, pp. 129-132), then your character subtracts -3 from her difficulty when trying to do so.

Your clear sight also reduces your difficulty by -3 when you try to see through a disguise, a cloaking spell or device, or other attempts to conceal the truth from an onlooker. It does not, however, allow you to see through darkness, notice stealthing or invisible characters, or otherwise perceive something that you would not be able to see without this Merit; combining this Merit with the physical Merit: Acute Senses, however, could make you a formidably perceptive character.
