Mass Suggestion

This spell is the same as the third level suggestion spell, except that the illusionist is able to cast the spell upon more than one subject, provided the prospective recipients of the suggestion are within the 3" range. 

One creature per level of experience the spell caster has attained can be affected. 

If only one creature is the subject, its saving throw is at -2. 

The suggestion must be the same for all hearing it.
