Prerequisite: Nightblade 15, Path of the Bloodied Chain

Benefit: The nightblade can make the shadowy chains of her umbral shackles emerge from herself to terrorize foes that draw near. By spending two of her daily uses of umbral shackles, she can cause the effect to be centered on herself. The area of the umbral shackles stays centered on her for the entire duration, even if she moves. The nightblade can also adjust the size of this shroud as a move action from as small as a 5-foot radius up to its normal size, though the radius must be a multiple of 5 feet.
