You gain a brief glimpse into the future that allows you to arrange a coincidence of of events. When you manifeeeest this power, you can ready a standard action (without spending an action to do so) and use it whenver you choose before your next turn. Unlike the normal use of readied actions, you need not specify the condition under which you take your readied action. If you do not perform your readied action before your next turn, you lose that action.
If you spend 2 additional power points, you do not need to specify the standard action you are readying. In effect, you can take your normal move action and then take any standard action at some later point in the round, depending on how events unfold.
