Quicken Time

You speed up the time stream in an area, stretching and pulling it until time flows swift and wild. Any creature that begins its turn in the area is Quickened until the end of its turn and can use the extra action only to Stride or Strike. Unfortunately, speeding up time is much more difficult than slowing it down, and the effect is uneven and jittery, making accuracy between times painfully difficult; creatures inside the area are Concealed to those outside it, and vice versa.
