Every 5 levels from 45 to 105 there are training quests for maker which involve forging more and more complex and valuable items for the Alchemists. These quests give good EXP and they're fairly easy, but most of them require items from all over the world, so doing them one at a time will make you waste a lot of time on boats. Therefore, it's a pretty good idea to gather up the items before time. I made this list for my own use but I thought I'd share it. I also included the items needed to upgrade the skill level so this is basically everything you need for Maker. Do note that some quests needed the same item so if you're not 105 you may not need this much material. Also I tried to put the monster that the etc dropped from (I'm not sure I put the right name for some of them) but if you need to know where they come from just ask.
