thats a very good point.
thats was my shorthand when writing for the "every 5th level" increase abilities, that they would evolve.

when i was actually writing it up on gamefaqs, i felt like it would be easier to stat explicitly when these abilities improved, and also felt that evolution as a levelling up mechanic sounded like i was cribbing off prototype 2 (which came out between me starting and finishing this class)
will replace with "ability improvement" in the table, thanks!
