Illusory Script

This spell allows the caster to write whatever they want on whatever they want. The caster specifies who they want to read it. (This can be an individual, class of individuals, a group, etc.) For anyone else this appears to be an unintelligible magical writing of some kind, though an Illusionist will recognize it as an illusory script. Any unauthorized creature attempting to read the script must save vs. Spells or fall under the effects of a suggestion. The suggestion only applies for 30 minutes and must be very short and simple (for example, “Put this down and leave”).
