This spell is used to stop all mental and psionic powers from affecting a specific being. This is accomplished by creating a field around the being affected that stops all mental energy from passing through it. This field however stops the mental energy from both entering or leaving. Thus, this could be used to stop a psionicist from using any powers on anyone but himself. It also grants immunity to any psionic attacks, including the dreaded mind flayer mental blast. It provides protection from any spell that deals with the mind of the person protected as well as any psionic power. This spell is quite similar to mind blank, except that it provides full protection against psionics and a few other mental powers. The list of spells that are protected against is too long to list, but if a spell affects the mind of a being, it will not work. The material component of this spell is a diamond shield, worth at least 10,000 gp.
Dalen was a Red Wizard of Thay, but was overthrown by another wizard who had a psionicist working for him. Dalen researched a way to stop psionics from working, and partially succeeded. He was hoping that a wall or sphere could be created, but found that this was impossible, because all the research he found pointed to the fact that such a field would have to be in close proximity to a living being, no more than an inch away in fact. Dalen later died when he tried to cast this spell on a psionic lich. Since the spell only affects living beings, which a lich is obviously not, Dalen was reduced to a mental vegetable and subsequently killed.
