The foresight sub-school has a supernatural ability called Prescience.
Prescience (Su): At the beginning of your turn, you
may, as a free action, roll a single d20. At any point before
your next turn, you may use the result of this roll as the
result of any d20 roll you are required to make. If you do
not use the d20 result before your next turn, it is lost. You
can use this ability a number of times per day equal to 3 +
your Intelligence modifier.
I have played a divination wizard up to level 13 when, at the beginning of the last game, the GM railroads me into a situation where I wake up with a cut on my wrist and I have a permanent 6 negative levels (not removable) and all my equipment missing.
When I expressed my discontent, I was informed that I was "cheating" by using Prescience for my skill rolls when it states that Prescience can only be used at the beginning of your turn. The GM's argument is that a turn system only applies to combat, hence I can only use Prescience in combat.
I have been using it for skills outside of combat: diplomacy, acrobatics, etc. This makes sense to me: you have a 6th sense that you are about to trip and you can make two d20 rolls for acrobatics. Or in diplomacy, where you can anticipate the NPC's response and sway the argument in your favor.
My question is:
Is Prescience usable for skill rolls outside of a combat situation? Another thread seems to suggest that I can: http://paizo.com/forums/dmtz2tl2?Foresight-School
