The spell Psychic Surgery says, "Reveal this card and choose a number less than or equal to your Intelligence or Perception modifier. Shuffle that number of random allies, blessings, and spells from your discard pile of a character at your location into his deck, then discard this card."
My Character, Estra, currently has a Wisdom +4 and Perception: Wisdom +2. When I make a Perception check my modifier appears to be +6, But an argument can be made that the Perception specific modifier is +2 and I also get to add my Wisdom modifier of +4.
For the purposes of identifying my Perception Modifier for the spell mentioned, is it +2 or +6?
