Rigidity (Psionic)

This power stiffens the joints and musculature of the affected creature, slowing it gradually until it can barely function. Only man-sized creatures or smaller can be affected. Most undead, such as skeletons and zombies, are affected, but non corporeal creatures are not.
The power's effectiveness is measured in stages. The first stage is attained after the initial cost and successful power check. The second stage is reached on the first round that the power is maintained, and the third stage on any rounds maintained after that. After maintenance stops, the creature gradually recovers its agility, one stage per round until normal.
