| 1 Regardless of the action, if you move out of a threatened square, you usually provoke an attack of opportunity. This column indicates whether the action itself, not moving, provokes an attack of opportunity. | 
| 2 If you aid someone performing an action that would normally provoke an attack of opportunity, then the act of aiding another provokes an attack of opportunity as well. | 
| 3 If the object is being held, carried, or worn by a creature, yes. If not, no. | 
| 4 If you have a base attack bonus of +1 or higher, you can combine one of these actions with a regular move. If you have the Two- Weapon Fighting feat, you can draw two light or one-handed weapons in the time it would normally take you to draw one. | 
| 5 May be taken as a standard action if you are limited to taking only a single action in a round. | 
| 6 Unless the component is an extremely large or awkward item. | 
| 7 These attack forms substitute for a melee attack, not an action. As melee attacks, they can be used once in an attack or charge action, one or more times in a full attack action, or even as an attack of opportunity. | 
| 8 The description of a Skill defines its effect. |
