It was very interesting to expand the places to explore by buffing them with item synthesis. It was nice to have a surprise each time I progressed, as the landscape would change dramatically with just a little progress in the exploration locations.
Also, I noticed something while playing the game. I didn't realize that the magic synthesis system doesn't produce synthesis predictions without failures, so I was stuck not being able to make Fire Protection.
Also, after seeing the End at the top of the mountain, I started the game over again and tried to see the End at the foot of the mountain, but for some reason it ended up at the top of the mountain.
