Sweet, rich, and unique in smell, can be used to add flavor to Foods and materials.
Cinnamon can be gathered by chopping Cinnamon Trees at the top of both sides of the waterfall (by WOW Industries) and can also be found on the Western Plateau to the west of McDonald's farm. The appropriate tree is medium thickness with yellow flowers.
In winter the flowers can't be seen, but the trees still give cinnamon. Look for a tree that has longish oval leaves (longer than the usual deciduous trees), typically a stump of a cut branch or two near the ground, and the cinnamon tree does not give you the option to 'kick' when you approach it.
