Chapter 8: Playing the Game / Perception and Detection / Detecting Creatures

Hidden

Source Player Core pg. 434
A creature that's hidden is only barely perceptible. You know what space it occupies, but little else. Perhaps the creature just moved behind cover and successfully used the Hide action. Your target might be behind a waterfall, where you can see some movement but can't determine an exact location. Maybe you've been blinded or the creature is invisible, but you used the Seek basic action to determine its general location based on hearing alone. Regardless of the specifics, you're off-guard to a hidden creature.

When targeting a hidden creature, before you roll to determine your effect, you must attempt a DC 11 flat check. If you fail, you don't affect the creature, though the actions you used are still expended—as well as any spell slots, costs, and other resources. You remain off-guard to the creature, whether you successfully target it or not.
