There is a bot undead level 58 at Lake Kel’theril in Winterspring. I invite you to kill it many times. The best strategy is to get him at 10% and let the monsters finish him so his equipment gets red. Good luck.
Horde can kill them too. I used to do this with my warlock. I would follow the bot (who is on the same faction as me) around and when they started to attack a mob I would keep fearing the mob. The mob would run and gather up its friends and they would kill the hunter and pet lol.
