Walk

Move along a relatively horizontal and solid surface. If there is no surface below you, you will begin to Fall (see Fall Damage) and cannot otherwise move yourself.

This is the default Movement Style that is active if no other Movement Style is active.

While this Movement Style is active, you can become Prone. While Prone, half any all Movement spent on this Movement Style before moving. You can become Prone as a Free Action. You can also stop being Prone as a Free Action, if you also spend a Swinging Distance(1u) of Movement. (Note: Abilities like the Basic Attacks are often affected by a Prone target, making that target harder or easier to hit.)
