SSandro, I'm not a super pro, but I'll try to figure it out...

Question for those who know: is it possible to make it so that when taking a book with all air spells, if the "Dimensional Door" and "Fly" spells are disabled in the "In the Wake of Gods" settings, they do NOT appear? Or is it necessary to create a new artifact with similar properties (if so, how do I do it? I mean, can I make it so that when wearing the artifact, spells are added, but how do I remember the spells that the hero learned BEFORE wearing this artifact and while wearing it, so that they don't disappear when the artifact is removed?).
