I'm no fan of DLC but this is one defiantly worth getting. The Stone Prisoner is basically a new character for your party which you obtain through a small quest. The quest itself is not long but does an excellent job of giving the new character some background, I won't say more because I don't wish to spoil it. At the end of the quest you are joined by Shale, a golem who will follow you. In combat he makes an excellent tank and he'll take a lot of punishment, he can dish it out too. Out of combat he is one of the funnier characters, his outlook on things is not unlike that of HK-47 from the Knights Of The Old Republic games. His story doesn't end once you get him either, it possible to find out even more later in the game. All in all money well spent and highly recommended.
