From the introduction: Everyone loves options, especially in Dungeons and Dragons where character building is half the fun of the game and this is what the Power Packs are about: Options. This power pack for Rogues introduces a slew of At-Wills, Encounter, Utility, and Daily powers. All of these powers are designed to work with existing builds and also help shape out the game where the Rogue may be lacking in a particular play style. These powers will allow you to play the Rogue how you want to play them!
