Power-Ups

Power-Ups are one-use Combat items that can boost your units, weaken enemy units, or do damage to enemy units.  Power-Ups can be purchased from the Build menu: Or during combat by clicking Select Power-Up: Which brings up all the Power-Ups you currently possess and can use: All Power-Ups cost Empire Points. To use a Power-Up in a fight, click Select Power-Up, select the Power-Up you want to use, and click the target of the Power-Up.  A Power-Up takes effect immediately.  Using a Power-Up in Combat expends one attack round. More potent Power-Ups are unlocked by leveling up.  Free Power-Ups can be earned by leveling up your Honor and Infamy.  How many Power-Ups you have can be viewed in the Power-Ups tab in your Inventory:   http://support.zynga.com/cp_articleview?gameId=81&Id=kA160000000GofyCAC&lang=en_US&loc=en_US
