A little something I thought of. Invisibility Potions, Feign Death and Shadowmeld is a pretty amazing combination. This serves no purpose, but it's doable, for the fun of it. Anybody doing this for grinding must be insanely patient and also very lucky with drops if he wants it to pay off.

THIS IS OFFICIALLY CONSIDERED AN EXPLOIT BY BLIZZARD, AND THEREFOR I DON'T ENCOURAGE ANYBODY TO TRY THIS AT ALL. The way I kill the Lava Surger is considered exploiting its set path and is not a legitimate way of killing something in World of Warcraft. .
