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) ?
That's a lot of odd numbers, which doesn't really get you anything. It would make more sense to just start with 16 DEX.
I kept to the standard array, as it seems companion characters are built with them. As Wyll is human, he, like Gale, will have quite a few odd numbers.
Even if it wasn't for the standard array, no companion starts with two 16s. Wyll already has 16 CHA, so the best he could have in DEX would be 14 or 15.
