Warding chaos is a warlock at-will utility power. It is the elemental pact boon granted at 1st level to hexblade warlocks who choose the elemental pact. Once per round, in response to dropping an enemy to 0 hit points or being adjacent to an enemy that is dropped to 0 hit points, the warlock can use warding chaos as a free action to gain resistance to multiple damage types and to shift.[HotEC:98]
