A character’s Perception measures what they are able to see, hear, or otherwise sense (unlike Investigation, Perception doesn’t involve approaching, searching, or handling an object of study.) The most commonly used ability score is Wisdom. A character might use Constitution for a long stretch of sentinel duty, or Intelligence to pick up on changes to the type of stone bricks used deeper than elsewhere in a dungeon. *Specialties: farsight, invisible objects, listening, scent.*
