A growth rate is the chance that a level-up raises one stat. Fire Emblem: The Sacred Stones rolls each of seven stats on the character’s own percentage at every level, and rerolls up to twice when nothing rises1. Non-player units placed with autoleveling, other than bosses and units with character numbers below 0x40, get their levels at once instead: one roll per stat on the class’s growth times their levels, moved at random by up to an eighth2.

Fire Emblem: The Sacred Stones 2004In the North American build, a level-up rolls each of seven stats on the character's own growth rate, with one random number from 0 to 99; each full 100 of a rate is a sure point, and if no stat rises, the game rerolls the stats in order up to twice, stopping at the first that does.Code
In the North American build, a non-player unit placed with autoleveling, unless it is a boss or its character number is below 0x40, adds to each stat one roll on its class's growth times its levels above 1, moved at random by up to an eighth of that product either way.Code
