Pally Power is an add-on that provides an interactive and easy to use interface that allows you to control assignments of blessings for yourself and, if you are a party leader or an assistant, for other paladins in your group or raid. Pally Power supports six blessings: Blessing of Might, Wisdom, Salvation, Light, Kings and Sanctuary. You don't need to be a paladin to control raid/party blessings.
Normally PallyPower displays a cast window that shows you how many people require blessings and timers for remaining time of your blessings. The cast window displays one button per each class you were assigned to buff, including hunter and warlock pets as a separate 'pet' class. Each class button displays an icon with an assigned greater blessing, a class icon, a remaining buff timer and a number of unbuffed and/or dead players. Each class button allows you to cast both greater (left mouse click) and lesser blessings (right mouse click).
Left mouse click provides an automatic buff and target selection: Pally Power checks the party or the raid roster to find a nearby person of a specific class, verifies that the person is in range and casts the blessing. After each cast the name of the person and the buff is stored until the next cast to allow re-cast of the same buff in combat.
