Some of the text in the Book of Shadows can go out of bounds, not 100% on why this is happening tried changing resolution and GUI scale but it looks the exact same. Just to be sure I tried a minimal installation with just the four mods listed above in Forge 14.23.5.2847 and the same thing happens

This is probably intentional but the green witch hood doesn't have the face blackout effect that other similar helmets do

The Stone and Gold versions of the Herne statue drop when broken in creative mode, no other statue or block in the mod does this

This last one is really just a suggestion but I think that showing a live showcase of the trees and ores in the guide book (similar to the How to Build page on the Altar) rather than showing a screenshot would bring some extra polish to the book and would also show what those look like if the user has a resource pack that changes those textures
