to be honest with you when I reached level 44 I started training on Oslya raptors. If you have decent defense and a glaze table and wood you can cook the food that they drop.

Out of all the monsters you can fight I'm pretty sure raptors drop the most. Most of what the raptors drop can be made into 160-275 HP items via the glaze table. Also if you have noodles the drops from raptors allows you to make Meats Noodles (+800 HP)
