Feats. They're pretty awesome. You get them about every 4 levels, if you want, in D&D, and they can really define some cool moves and abilities to set your character apart from the others. In Unearthed Arcana, Wizards of the Coast posts up some playtest material for you to try out. And this time around, they're all new Feats for you to try. Have yourselves a look.
From the post:
Today’s Unearthed Arcana presents a selection of new feats for Dungeons & Dragons. Each feat offers a way to become better at something or to gain a whole new ability.
