Decipher Cript

New use of Decipher Script: Cipher.

Anyone with the Decipher Script skill can write coded messages. These are not readable with comprehend languages or similar spells; it would take specialized code-breaking spells to read them. Deciphering a coded message requires the Decipher Script skill; if you have the code key, the DC is 15, otherwise it is 20 + the encryptionist's Decipher Script skill bonus. If you have access to several pages of messages written in the same code, you can cross-examine them and get a bonus of +1 per page of code you have to work with. On attempt can be made per day of work.
