Encrypt

Regular 
When cast on any writing or other visual information medium, this spell makes it unreadable to any but the caster. Anyone can see the writing, but they will be convinced that it is hopelessly arcane, complex, or foreign. 
Other media dependent on the senses (including any arcane taste- or smell-based “writing” that might be used by nonhuman races, as well as Braille in modern settings) may be encrypted if the GM permits it.

Duration: 1 week. 
Cost: 1 for up to 1000 words of plaintext; 2 for up to 10,000 words of plaintext; 3 for up to 100,000 words of plaintext; +1 for each additional 100,000 words. Thus, a stack of six typical GURPS Fourth Edition sourcebooks, at about 175,000 words per book, would cost 12 energy to encrypt. 
Prerequisite: Daze.

Item
