Swift Death (3.5e Sacrifice)

You feel lightheaded and light footed as you suddenly accelerate into a blur.

You shed your life to travel at the speed of death, swift and deadly. As a swift action you increase your speed by +5 enhancement bonus for 1 round. For each additional hit point burned, this amount increases by 5 ft., spending no more than your class level in hp on a single round. For example, a 15th level Gate Knight could spend 15 hp, and increase his speed by +75 ft. for 1 round.

Health Cost: -1.
