I've been searching on the archive for information about the "first chapter all techniques found" record, and everyone has said that it means all the monsters have used their skills, but I just finished going through the encyclopedia and getting all the ones I missed, and still don't have the record. I've checked over it a few times and nothing is grayed out anymore, and I've also taken the special attacks for the other three records. It's not possible to miss an actual skill in the story, right? This is all that he learns?
