Speaking of the magic system...
Unless I'm missing something, and I likely am, I don't know how to cast 10th level spells. If I remember correctly, casting a spell starts on second 1 and finishes a number of seconds equal to the spell's level + 1. This would mean that a 10th level spell would go off on second 11, which does not exist within the same turn. Does a 10th level spell finish on the 1st second of the round following the turn a spell caster starts it?
Also, what determines limited ability in regard to spell casting? I know that White and Black Knights have particular schools that they're limited to, but I didn't find any of that in, say, the Scout profession. Does limited ability refer to the number of learning points a profession received based on XP?
