Quantum Roleplaying

In quantum mechanics there's this idea of wave function collapse, in that interaction with a measuring device supposedly causes a wave function to reduce from a plurality of eigenstates to just one. My interpretation is that it's simply saying this: before you roll a die, there is a probability that it lands on any face (for d20: 5% 1, 5% 2, 5% 3, etc.), but the instant you actually roll it the possibilities collapse to just one (100% certainty about the particular result that you rolled). *

It seems to me that this is quite similar to the moment in RPG's when a designed scenario full of  possibilities switches to a narrative story, at the point in time when you actually play it. That is, "scenario becomes story" when the dice hit the table and we find out what actually happened. Prior to that moment there are endless possible outcomes -- a statistical space, really -- whereas afterward there is one known outcome which we then seek to explain as a "story". Story generally exists only after the fact, not before play, in RPG's. *

We might more broadly say that this occurs in any live performance: theatre or music, for example. Technically many possible exciting things can occur which we only know about for sure after the fact. However, this phenomenon is several orders of magnitude easier to see in RPGs, which has such an overabundance of possible outcomes (in conjunction with both player choices and random die-rolls), as opposed to theatre or music, where the script and rehearsal set a relatively narrow expectation for what should happen in the performance.

* Note: This is a heretical interpretation on my part.

New Magic Item: Arrow of Time

This very rare arrow acts as +3 to hit and damage. On the round when it is fired, probabilities for critical hits or fumbles are tripled (i.e., if normally 1 or 20, become 1-3 or 18-20) for all parties in an encounter. If hit, then the target must save vs. spells or else only achieve average results for the rest of the encounter (i.e., automatically roll a natural "10" for any to-hit roll or save, exactly average damage or spell duration, etc.). It is occasionally produced by chronomancers and best used by parties who are overwhelmed by stronger forces and expect to lose the fight without extraordinary help.
