Hello,
I saw once, a streamer hunting as EK 650+ with good equips solo on Ferumbras Entrance, but in my point of view, it is not the best level to hunt there solo, it's not comfortable as you can think, you will have to hunt having the hand ready to eat a food everytime, and with a great risk of dying... My suggestion, is going there at least 800+ for any vocation, and not telling that there will be the best hunt and profitable place in Tibia to go. We have many examples of hunting grounds and videos teaching how to and which equipments are the minimum required to use there. Take a look on Youtube or even Twitch, to have better examples.
