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 clerics 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 cleric may be lacking in a particular play style. These powers will allow you to play the Cleric how you want to play them!
