I was interested in starting another wizard, to play along with my grandadughter who is not as ambitious as I am on advancing. Can one account have more then one wizard? I don't want to lose my kiley who has worked up to lvl 36.
The answer is "Absolutely, Kiley!" Here's a picture of my start screen on my 1st account.
As you can see, I have six characters on one Wizard101 account (that's the max). All you have to do is click that "new" button down on the bottom of that screen and you'll soon have a totally new character at your disposal. The only way to delete one of those characters is to select them and click the delete key, then type abracadabra. So don't worry about accidentally deleting your character. AND, if you do happen to somehow accidentally delete your character, Kingsisle's support staff is awesome at restoring your characters. No worries.
Have fun with your new characters!
