Minimum Attack Speed is 3

I do not believe Exalted Standard Rules ever set a floor for attack speed. But the entire game mechanic breaks down when Attack Speed is reduced too low. Thus I am setting a floor value.

The Minimum Attack Speed of any attack is going to be 3, no combination of effects, however Legendary or Unique, can reduce attack speed to lower than this.

There are effects that can fit more attacks into this time frame. Such as Extra Action Charms, or Ridill (Reaper Daiklave that attacks twice for every attack the wielder makes with it). But the basic speed of the attack action, and thus DV refreshes, Charm Activations, etc., cannot be lower than 3.
