The value of being able to choose a Limitation on the fly is considerably less than a fixed Limitation, as it becomes very easy to avoid either Limitation actually coming into play. (They'd both have to apply to the use of the power; otherwise, the proper munchkin would simply choose the one that wouldn't actually affect his character, thus effectively never having a Limitation.)
Sorcery has an "Alternative Rituals" rule (p7) that as a specific case (rather than a generalized rule for any Limitations) lets you substitute any two of three possible spell-casting Limitations for the standard Costs 1 FP Limitation. PK generalizes the Either/Or logic to arrive at a result of half value for choosing any two of the three (or four) Limitations in the set, all normally -10% -- so choosing two -5% -5% = -10%, matching the standard Limitation. (Or so PK argues, as he is among the many that find that a more fair price for Costs FP than the book value of -5%.) |
