Brain lock

Brain lock was a psionic power of the telepathy discipline. It prevented the victim from undertaking any mental actions.

Effects
If the target lacked the will to resist, their higher mind was locked away and they became dazed and mentally paralyzed, unable to actively perform any actions, even purely mental ones. They couldn't move or attack, nor make decisions, nor cast spells or use psionics. A flying creature, unable to beat its wings, was forced to descend and land, while a swimming creature was forced to stop, and an air-breathing one to head to the surface. However, they could still react and defend themselves against any physical assaults. This made other forms of mental control redundant, as the subject could not move or act even if commanded by another.

It affected one humanoid up to 130 feet (40 meters) away, or longer for more capable manifesters, and lasted as long as the manifester concentrated, plus several seconds. An experienced manifester could augment it with additional psionic energy to affect other types of creatures, but could not change the number or range.

Displays
Manifesting it had the standard visual and material displays.

Users
Brain lock could be learned by telepaths and ardents and divine minds who bore the Corruption and Madness mantle, as well by crystal dragons, who were natural telepaths. Brain lock could also be used innately by the psionic demons called cerebriliths.
