Crafting is a fun way to make some gold. Just make the equipment and pick a couple items you would like to make. It also helps to have a few alts to help collect the materials needed to make stuff. Once you have all the equipment in place you can start cranking out all kinds of tent equipment that people will buy because they are too lazy to make it themselves.

I have noticed that there are not as many tent equipment sellers anymore. So I bet you could make alot of gold.

In my opinion, I think its a waste of time to make syrups. Especially since you can buy 400sp food in Japan. Also, with the free items you get daily, we now get the sp and hp restore packs. I use them now when training or bursting.
