A character’s speed tells how far he or she can move in a move action. Humans normally move 30 feet, but some creatures move faster or slower. Wearing armor can slow a character down.
A character normally moves as a move action, leaving an attack action to attack. The character can, however, use his or her attack action as a second move action. This could let the character move again, for a total movement of up to double his or her normal speed. Another option is to run all out (a full-round action). This lets the character move up to four times his or her normal speed, but a character can only run all out in a straight line, and doing so affects the character’s Defense (see Run).
