Traditions arcane, occult

Cast [>>] somatic, verbal

Range 120 feet; Area 20-foot burst

Duration 1 minute

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 and can use the extra action each round 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.
