Still, in the book, all stats except for STR or MAG depending on if you're a physical or magical unit require at least 10% in their growths<br/>And actually, a lot of the games are built around your units having a Luck Stat. The book seems to take a lot of cues from the GBA games, where Luck affected hit minorly, evasion majorly, and was the sole thing behind reducing enemy Critical rates.
