Caught another error on Barcan's sheet: Blazing Starfall initially does radiant damage.
Boy, Barcan - Human Cosmic Sorcerer (Veiled Alliance), is a poster child for why you do not want to put an 18 into a stat before racial modifiers. He could really use some defenses and hit points. And he cannot take armored proficiency for a long time either.
Agreed. I'd build him like this:
Str 16, Con 12, Dex 10, Int 12, Wis 8, Cha 18
Armor Proficiency (Leather), Improved Initiative
AC: 15, Fort: 14, Reflex: 12, Will: 17
HP: 24, Surges: 7, Surge Value: 6
Insight +4, Arcana +6, History +6, Diplomacy +9, Bluff +9
When he hits 11th Level he qualifies for Armor Proficiency (Hide) and most, if not all, arcane multiclass feats.
