Since the crunch aspects of this seem to be fairly well under control, I pose a query from a different direction:

This class requires Arcane Evaluator 10, and is described as an organization of Evaluators. Where is the connection between seeing the numbers that make up everything and judging souls with uniquely crafted weapons? This seems like a completely divergent theme that could stem from any number of base classes.

With an entry requirement so nonstandard as "X Class level 10" I expect the connection to the base class to be inextricable and strong, but the way this is set up, basically anything could make sense becoming a Reaper.
