The Chosen Ones

I finished Extreme and chose +1 stat on level up, but in Chapter 3, though Galeoth gains extra stat on level up, his starting stats seems so low.. In chapter 5, Fradz and Phodom each has about 40-50 all stats more than Galeoth... I don't know if this is because Galeoth starting level is 40 or not...

One more thing, I think Crate of Wonder should be apply to all chapters. I mean, if I kill that box in chapter 1, in chapter 2 and chapter 3, Fradz and Galeoth should also receive the bonus from it.
