Precognition is just hard on the GM.
I have got some good use out of Psychometry, in an occult investigative game. The initial build was:
Psychometry, Costs 4 fatigue -20%, Magical -10%, Preparation Required (10 minutes) -30%, Reliable (+2 to roll) +10%, Takes Recharge (1 hour) -30% [4].
This has got modified, to make it more useful, and when I understood the distinction between Preparation Required and Immediate Preparation Required, the latter always being the way it was intended to work:
Psychometry, Costs 2 fatigue -10%, Magical -10%, Immediate Preparation Required (10 minutes) -45%, Reliable (+2 to roll) +10%, Sensitive (Gives uneventful history as well as high points) +30%, Takes Recharge (1 hour) -30% [9].
