Illusionary Script

This spell enables the illusionist to write instructions or other information on parchment, paper, skin, etc. 

The illusionary script appears to be some form of foreign or magical writing.

Only the person (or class of persons or whatever) whom the illusionist desires to read the writing will be able to do so, although another illusionist will recognize it for illusionary script. 

Others attempting to read it will become confused as from a confusion spell (q.v.) for 5 to 20 turns, minus 1 turn for each level of experience he or she has attained. 

The material component of the spell is a lead-based ink which requires special manufacture by an alchemist.
