Once you are 12 you can try Misty (1st step in

I tried to afk camp her once I got my 16 pet but after a few kills he got unlucky and died, and she came running and killed me (can't stay FD or pet won't agro). So you could probably with the 20 pet but the exp at the point would be worthless. In conclusion, afk camping not really effective!
