Like You Died, Soul Arts also has a secret message encrypted on its last page.
Soul Arts’ page 277 shows a gold star field.
Filling the 26 columns on the page with the letters of the alphabet assigns each star the letter of the column it belongs to.
Reading the largest stars from top to bottom reveals the secret message. It’s a quote by Demon’s Souls’ Stockpile Thomas:
“You have a heart of gold.”
