Saeviomagy said:Or precisely what we're saying - that you need to use a special monk weapon to flurry with. I don't understand how you could interpret it to mean the opposite.
If something says you "may" do it with certain weapons and never specifies any other situation in which you can do it, you may ONLY DO IT WITH THOSE WEAPONS. However, in the case of the monk, I believe it states you can also do it unarmed.
So - special weapons or unarmed only.
I have now read the description on flurry of blows (PHB 3.0 - page 39 - second printing: November 2000) over and over again. And I must say that I cannot interpret it to mean that I HAVE to use a special monk weapon OR unarmed (or a combination of the two...). I interpret it as if I may use any weapon I'm proficient with to get an extra attack "at the expence of accuray."
But hey, feel free to convince me by stating something else written or other interpretations (difficult word =P) on this matter...
