My housemate is a WoW fanatic. He constantly regales me with explanations of his new abilities and adventures, and often begs me to "power level" his characters (play them for him while he's out working, so that he can advance faster). He also ventures strong opinions about certain types of characters in the game and their relations to their players' likely sexual perversions. I would therefore like to create a new character for him to play. Is this doable without damaging anything? I don't want to wreck his game, just give him a few new options to further explore his in-game personas and their sexualities.
How do you create characters, and is there a limit on the number you can play on one account or in one "realm"? Can you have characters of widely different types, i.e., create "hunters" as well as "wizards", without screwing anything up? I don't want to cause his existing ones to disappear (he's got them up to pretty high levels, and with "expensive" in-game equipment), only to create a new one.
