An noble which is only lv 1 makes no sense either.
Why is it that being a Noble and being Level 1 should be a problem exactly ? Are Forgotten Realms Nobles born with an advantage to XP, in addition to everything else (wealth, rights, etc) ?
No, but he could have payed tuition with the best magicians, he could adventure with a lot of money to pay for expensive scrolls to slay powerful mosnters and so on. Most nobles on neverwinter nights 2 are above lv 10.
