I'm not sure if this is by design or a bug, but here it is :

Apparently, to unlock the Book of the Dead Gods, the Paladin option uses a Widsom check.

However, the action attempted here is to channel their divine power to unlock the book. Which means, they should use their spellcasting ability, Charisma.

There might be other instances of this. I'm unsure.
