Feats

At class levels 4, 8, and 12^{[Needs Verification]}, players can choose to take a feat instead of increasing their Ability Scores. Feats are character features that grant unique abilities or bonuses which improve a character's abilities in specified areas.

 Fighters and  Rogues also gain access to bonus feats, with the fighter gaining a bonus feat at level 6 and the rogue at level 10.
