A psion who chooses clairsentience is known as a seer. Seers can learn precognitive powers to aid their comrades in combat, as well as powers that permit them to gather information in many different ways.
As long as you maintain psionic focus, you may manifest either of your chosen powers without paying a power point cost, but the power may not be augmented or affected by metapsionic feats. The competence bonus from call to mind is reduced to +2, the duration of destiny dissonance is one round per two psion levels, and the duration of offensive precognition is 1 round per psion level.
At 2nd level, as long as you maintain psionic focus, when someone successfully saves against a Clairsentience power you’ve manifested, you learn about a single psionic effect currently in effect (if any) on the target. Each subsequent successful save against a Clairsentience power you manifest transfers information about another psionic effect currently in effect (if any) on the target. If there are no psionic powers in effect on the target that you do not already know, then you learn information about a single psionic item the creature currently possesses, as if you had identified the item. This effect does not give any information on artifacts. The number of psionic effects or items you learn about per save increases by one every four psion levels thereafter.
At 8th level, each day when you meditate to regain your power points, you gain a +3 insight bonus that can be used on any one die roll. Every two psion levels thereafter, this ability may be used one additional time per day and the insight bonus is increased by 1.
At 14th level, once per day, you can automatically identify all properties of a magic item, magic aura, or identify a spell or power in effect. In addition, if you are being scryed upon, you can expend your daily use of this power as an immediate action to disrupt the scrying attempt and instead scry on the originator of the effect using the same effect as that which targeted you. You need not pay any power point cost for this ability, although the originator can make a save to block the attempt (same DC as the original scrying attempt). This ability does not work on artifacts.
At 20th, your ability to foresee the different possibilities has suffused you. Anytime you roll a d20, you may expend your psionic focus as an immediate action to roll a second time. To choose the result of the second roll, you must pay the unmodified die roll in power points.
