During Early Spring, be sure to look out for limited Treasure Beasts in the Interior! These Beasts look like a pre-(H)istory animal called a "rabbit", but contain many delicious and rare food stuffs as well as the occasional magica item!
Be warned, these rabbits have a jumping biting attack where they aim for the throat, so be sure to have proper armor or protections in place.
Happy Hunting!
