Cover: When you’re behind a physical obstacle, you get a +2 circumstance bonus to AC, Reflex saves vs. area effects, and Stealth checks. This increases to +4 for greater cover. Creatures can provide lesser cover: a +1 circumstance bonus to AC.
Hidden
While you’re hidden from a creature, that creature knows the space you’re in but can’t tell precisely where you are. You typically become hidden by using Stealth to Hide. When Seeking a creature using only imprecise senses, it remains hidden, rather than observed. A creature you’re hidden from is flat-footed to you, and it must succeed at a DC 11 flat check when targeting you with an attack, spell, or other effect or it fails affect you. Area effects aren’t subject to this flat check. A creature might be able to use the Seek action to try to observe you, as described on page 471.
Undetected
When you are undetected by a creature, that creature cannot see you at all, has no idea what space you occupy, and can’t target you, though you still can be affected by abilities that target an area. When you’re undetected by a creature, that creature is flat-footed to you.
A creature you’re undetected by can guess which square you’re in to try targeting you. It must pick a square and attempt an attack. This works like targeting a hidden creature (requiring a DC 11 flat check, as described on page 466), but the flat check and attack roll are rolled in secret by the GM, who doesn’t reveal whether the attack missed due to failing the flat check, failing the attack roll, or choosing the wrong square.
A creature can use the Seek action to try to find you, as described on page 471.
