Prerequisite: Nightblade 9, Path of the Eternal Night

Benefit: The deathly energies of the nightblade's corruption linger, harming creatures even after they move away. A creature harmed by the nightblade's corruption that leaves the area must make another save against the nightblade's corruption at the start of its turn, as if it was still in the area of the corruption. This only occurs the first round the creature is outside of the corruption, though if it reenters and exits the area this effect will apply again. A creature can still only be harmed by corruption once per round.
