a perk on page 44 of psionic powers
moves a success roll up and is cheaper than Influencing Success Rolls on B347 specifically Buying Success
normally that costs two character points for either upgrading a critfail to a normal one, or upgrading a normal success to a crit success - it is half price for investing a free character point like this in advance
This is similar to Heir under Potential Advantages where double the value is eventually gained from what is set aside, except the player decides when to use it instead of the GM
