Extra Skill

• Type of feat: General
• Prerequisite: None.
• Required for: N/A
• Specifics: Choose a skill you do not have as a class skill. Because of your background or through dedicated training, you may treat this skill as if it were a class skill for you.
• Use: Automatic. This feat may be selected multiple times, but the effects do not stack. It applies to a different skill in each case.

Update

Extra Skill feats are no longer available for general selection. Instead, class skills are now fully unlocked once a class or feature grants you access to it. Characters can invest in class skills on any level as long as that skill is a class skill for at least one of their classes (or is granted by another feature, such as history feats or domains). This means that, if you take a rogue level, hide will be still be available to you as a class skill even if you later level up as a fighter, even though hide is not a class skill for fighter.
