Text Decoder

FEAT 4

Thanks to your constant involvement with cryptic texts, you have attained an almost-supernatural ability to decipher complex codes and understand ancient writings. You can always use Occultism or Religion when you Decipher Writing, no matter the subject matter. In addition, you can ignore language constraints when Deciphering Writing, and when you critically fail to Decipher Writing, you get a failure instead.
