Re: Bag of Tricks: Choosing actions via the matching law

What knowledge should supposed?  It is understandable to suggest that hitting some
monster with fire arrows to no effect might suggest changing weapons.  But should
that knowledge be presupposed?  IF so, then you wouldn't want to shoot at it in the
first place.  But what is the implication of presupposed knowledge?  What about the
next time you encounter a similar beast?  Behaps the fire arrow immunitity was
imparted not by a trait of the creature but a protective spell. The second encounter
might not have such a protection and fire arrows might be the most effective tool to
dispose of the threat.
