Quote: SPOT (WIS)
Check: The Spot skill is used primarily to detect characters or creatures who are hiding. Typically, your Spot check is opposed by the Hide check of the creature trying not to be seen. Sometimes a creature isn’t intentionally hiding but is still difficult to see, so a successful Spot check is necessary to notice it.
A Spot check result higher than 20 generally lets you become aware of an invisible creature near you, though you can’t actually see it.
Spot is also used to detect someone in disguise (see the Disguise skill), and to read lips when you can’t hear or understand what someone is saying.
Spot checks may be called for to determine the distance at which an encounter begins. A penalty applies on such checks, depending on the distance between the two individuals or groups, and an additional penalty may apply if the character making the Spot check is distracted (not concentrating on being observant).

Condition Penalty
Per 10 feet of distance –1
Spotter distracted –5

Read Lips: To understand what someone is saying by reading lips, you must be within 30 feet of the speaker, be able to see him or her speak, and understand the speaker’s language. (This use of the skill is language-dependent.) The base DC is 15, but it increases for complex speech or an inarticulate speaker. You must maintain a line of sight to the lips being read.
If your Spot check succeeds, you can understand the general content of a minute’s worth of speaking, but you usually still miss certain details. If the check fails by 4 or less, you can’t read the speaker’s lips. If the check fails by 5 or more, you draw some incorrect conclusion about the speech. The check is rolled secretly in this case, so that you don’t know whether you succeeded or missed by 5.
Action: Varies. Every time you have a chance to spot something in a reactive manner you can make a Spot check without using an action. Trying to spot something you failed to see previously is a move action. To read lips, you must concentrate for a full minute before making a Spot check, and you can’t perform any other action (other than moving at up to half speed) during this minute.
Try Again: Yes. You can try to spot something that you failed to see previously at no penalty. You can attempt to read lips once per minute.
Special: A fascinated creature takes a –4 penalty on Spot checks made as reactions.
If you have the Alertness feat, you get a +2 bonus on Spot checks.
A ranger gains a bonus on Spot checks when using this skill against a favored enemy.
An elf has a +2 racial bonus on Spot checks.
A half-elf has a +1 racial bonus on Spot checks.
The master of a hawk familiar gains a +3 bonus on Spot checks in daylight or other lighted areas.
The master of an owl familiar gains a +3 bonus on Spot checks in shadowy or other darkened areas.

Quote: CONCEALMENT
To determine whether your target has concealment from your ranged attack, choose a corner of your square. If any line from this corner to any corner of the target’s square passes through a square or border that provides concealment, the target has concealment.
When making a melee attack against an adjacent target, your target has concealment if his space is entirely within an effect that grants concealment. When making a melee attack against a target that isn’t adjacent to you use the rules for determining concealment from ranged attacks.
In addition, some magical effects provide concealment against all attacks, regardless of whether any intervening concealment exists.
Concealment Miss Chance: Concealment gives the subject of a successful attack a 20% chance that the attacker missed because of the concealment. If the attacker hits, the defender must make a miss chance percentile roll to avoid being struck. Multiple concealment conditions do not stack.
Concealment and Hide Checks: You can use concealment to make a Hide check. Without concealment, you usually need cover to make a Hide check.
Total Concealment: If you have line of effect to a target but not line of sight he is considered to have total concealment from you. You can’t attack an opponent that has total concealment, though you can attack into a square that you think he occupies. A successful attack into a square occupied by an enemy with total concealment has a 50% miss chance (instead of the normal 20% miss chance for an opponent with concealment).
You can’t execute an attack of opportunity against an opponent with total concealment, even if you know what square or squares the opponent occupies.
Ignoring Concealment: Concealment isn’t always effective. A shadowy area or darkness doesn’t provide any concealment against an opponent with darkvision. Characters with low-light vision can see clearly for a greater distance with the same light source than other characters. Although invisibility provides total concealment, sighted opponents may still make Spot checks to notice the location of an invisible character. An invisible character gains a +20 bonus on Hide checks if moving, or a +40 bonus on Hide checks when not moving (even though opponents can’t see you, they might be able to figure out where you are from other visual clues).
Varying Degrees of Concealment: Certain situations may provide more or less than typical concealment, and modify the miss chance accordingly.
