In your Command phase, one or more CHAOS KNIGHTS units from your army can make a Malefic Surge. Each one that does must first take a Leadership test; if that test is failed, that unit suffers D3 mortal wounds. Then, until the start of your next Command phase, that unit is Empowered. While a unit is Empowered it can use one of the Malefic Surge abilities below. Once that unit has used a Malefic Surge ability, it is no longer Empowered.
Designer’s Note: We recommend placing a token next to CHAOS KNIGHTS models that are Empowered, removing it once they have used a Malefic Surge ability, and removing all unused tokens at the start of your Command phase
