To change your name or lower your stats, die. When the Grim Reaper shows up, click the hourglass on the bottom of his robe. He will give you a walk around quest. During the quest, enter the purple swirly object. If you are in a graveyard, click the gravestone. A person will appear. Lose the battle to lower your stats. If Twilly appears, you can change your name. Occasionally other things may happen.
