Actions in Pathfinder

Types of Actions in Pathfinder
Action	Number Per Round	Examples
Free	1-3	Brief actions: yell a few words, drop a weapon; total actually depends on DM and horse sense
Move	1	Has two subtypes: 5' step or normal move
Standard	1	A single attack, use of an ability, casting most spells
Swift	1	Initiate smite, start rage--an action not quite fast enough to be 'free' but quick nonetheless
Full Attack	1	When using FA, you may only take 1 swift action, 1 move (5' step), and as many free actions as the DM allows; you may not take a standard action or a move (normal move)
