Seriously, this new diary changes is kinda confusing. For starters, some minor spoilers for the Amateur spells quest below.
I got some help from Serity on this one, because the diary leads you in odd places. When I was done completing the Amateur quest and got the spells rittle, another entry was added to my diary. I sent to this place, got the item it was hinting at and eventually found who to give it to. I gave it to them, and my "amateur Spells" still had an "X" next to it. So I was like okay what am I missing? Turns out I was missing the part where I say hi to him to trigger the beginning of the quest. So basically, if I had been doing it right, I was to get the amateur rittle from oricle, go talk to this guy, get the object in question, give it to him, he exahgnes it for another item he gives me, I get the info from it and then do the Volcano part.
That's not how I did it t hough, and as a result I would've never got it fully complete if I didn't say hello to this hawk guy first.
Perhaps the diary shouldn't have given the Chimney hint part after the Volcano part was complete, instead telling me to go to the forest instead. However, I was drawn to the Chimney. The rittle hinted at the forest, but I had wondered why the chimney entry appeared there.
