Use Feat, Skill, or Talent

Certain feats, let a character take special actions in combat. Other feats are not actions in themselves, but they give a character a bonus when attempting something he or she can already do. Some feats aren't meant to be used within the framework of combat. The individual feat descriptions tell a character what he or she needs to know about them.
Most uses of skills or talents in a combat situation are attack actions, but some might be move actions or full-round actions. When appropriate, the description of a talent or a skill provides the time required to use it.
