Ok!!! I busted my ass off to find those. They are extremely easy to locate, BUT! Even MORE EXTREMELY EASY to miss. One location in entire Kamasylvia. Took me 2 hours googling and then went into korean pages with google translate and shizzle. So thank me for this! hahaha
Here they are!
Finaly reached 500 energy after finding those little foxes (Yes, they are foxes! not wolves! English BDO team lazy translators)
