One of the more powerful forms of attack used by psionicists is the spell known as 'mind disruption.' Through minor concentration they are able to mentally attack the mind of their victim. This sudden introduction of foreign mental power instantly overloads their mental thought processes. Not only does this cause intense pain as it attacks the nervous systems in the mind, it also is known to black the victims out for a short time, as their brains are temporarily overloaded from the attack.
