While we're asking questions what is the point of screenshot 3 and 4?
Anyway, a before and after screenshot would be more helpful. We already have a screenshot of demon portal - is that with or without the book equipped? Did the power go up 20% or 200%? What was it originally?
On second thought, just send an email to support (support(@)1cpublishing.eu) with your save game and they'll fix it if it's a problem.
