Description
You close your mind or your target's mind to outside influence, preventing spells or other perils that influence the mind from having effect. This includes charm-like effects, madness-inducing spells, as well as any form of psychic contact that affects thought (such as telepathy or ESP, but not all psionic spells in general). You must concentrate on closing your mind for the duration of the spell (or concentrate on protecting your targets, if they are the subject), or else the minds you seek to protect become vulnerable to psychic contact.
