If using these rules, Hide/Move Silently and Search/Spot/Listen should probably be merged.
Detect Presence (Wis)Check: Your Detect Presence check is either made against a DC that reflects how powerful the aura is that you might sense.
Success indicates that you notice the aura and its rough direction. If you can see the owner of the aura, you recognise it as theirs. Success by 5 or more lets you tell whether the owner's CR is greater than, lower than or equal to yours. For every +1 by which you succed on the DC, you can tell the owner's CR within 1 number of accuracy. For instance, if you roll 6 higher than required, you can tell if your opponent's CR is 2 or more below yours, 1 below yours, equal to yours, 1 above yours, or 2 or more above yours. If you roll 7 above the DC you can tell the CR range within 3 of your own, and so on.
Action: Varies. Every time you have a chance to sense something in a reactive manner (such as when someone casts a spell or you move into a new area), you can make a Detect Presence check without using an action. Trying to detect something you failed to detect previously is a move action.
Try Again: Yes. You can try to detect something that you failed to sense previously with no penalty.
Special: When several characters are training their senses on the same thing, a single 1d20 roll can be used for all the individuals' Detect Presence checks.
A fascinated creature takes a -4 penalty on Detect Presence checks made as reactions.
A ranger gains a bonus on Detect Presence checks when using this skill against a favored enemy.
A sleeping character may make Detect Presence checks at a -10 penalty. A successful check awakens the sleeper.

Conceal Presence (Wis)Check: Your Conceal Presence check reduces your effective CR for the purposes of Detect Presence checks. This can reduce your CR to a negative figure. You can always take 10 on a Conceal Presence check.
Action: Concealing your presence for 1 round requires a move action.
Special: If you possess the Tranquility feat, concealing your presence requires a swift action and you may make Conceal Presence checks while unconscious.

Sense Motive (Wis)Additional use: Analyse auraIf you have sensed someone's aura with the Detect Presence skill, you may make a Sense Motive check to determine its qualities. Make Sense Motive checks against each descriptor of the aura, applying the modifiers for the Detect Presence skill. Success indicates that you are aware of that quality of their aura.
