Walk
Walk
Type of Action: Move Action
A character can walk its speed with a move action. For most size-medium creatures, this is 30 feet. Moving like this is a cautious walk, and is primarily used during combat. Despite this, walking provokes attacks of opportunity from enemy creatures, if you leave a space they threaten.
Characters can only walk through unoccupied spaces or spaces occupied by allies, and any walk must end in an unoccupied space.
The only technical distinction between "walk" and "move" is that moves are a type of action, while walk is using a move action to move along the ground up to your speed. Otherwise, the terms are largely interchangeable. Similarly, if something refers to a creature's "base land speed" it is referring to how fast they can walk in a single move action.
