Growth Rate

Growth rates are a set of hidden stats that appears in each game in the series. For each increasable character stat, such as Strength or Skill, there is usually a growth rate associated with it. For playable characters, growth rates are the percentage change of a character gaining 1 point in a particular stat during a Level Up, with the Random Number Generator used to determine whether a stat increases or not. For example, a growth rate of 50% on average yields 1 stat up per 2 Level Ups.

In rare cases, growth rates may exceed 100%. In which case, 100% is subtracted off the growth rate and becomes a guaranteed +1 during a Level Up, with the remaining growth rate allowing for a chance of another +1. Since the maximum growth rate is 255% (due to the games' programming), the maximum stat increase is +3 (which is possible with Karel in Fire Emblem: Fūin no Tsurugi).

Enemy characters use a different set of growth rates, known as Class growth rates. Enemies do not Level Up in the traditional sense, but instead they are auto-levelled at the beginning of each chapter (or, for reinforcements, when they first appear). This is why enemies usually have slightly random stats.
