This is an ability that has a passive component and an active component:
A near innate ability to some psions
, Presentiment allows the psion to get brief glimpses of intent, fate and future. The flashes of insight allow the GM to guide the presentient psion to clues or things that might have been missed. The character may get a sudden flash of walking into a trap, or a strong sense of hostile intent (indicating an imminent attack or an alarm about to go off). Should the GM wish this ability to be less assured, she can roll a hidden check against the psions Psionics
skill against a difficulty she deems appropriate. The passive ability is always active (unless disrupted by White Noise
or other interference) and requires no active action from the psion to use.
A presentient psion can force a premonition through concentration. The psion spends a minute focusing their ability and clearly states a subject they wish to have a premonition of. They must then pay the PSI cost and perform a check against 9 or another difficulty set by the GM. The GM chooses how much information is divulged. Greater Excess should divulge more information.
