You can pay a fine at a wizard town. Just run to the town hall and bring tens of thousands of gold. Incidentally, if you only trigger Janod's -40 rep when you have the cash for this, you can get +40 rep with Thuram by getting Janod his orb after paying the fine.
Yeah same here. Im a lv14 wizard and got the orb/killed the wizard maybe at lv6 but only just realise why I'm considered a bandit in various place and the wizard guild doesn't like me. I haven't played since.
