Stat cap

Stat Caps are the maximum number a stat can reach for a given character. In other words, unless a character promotes and get a higher stat cap, they won't be able to gain any more points in that stat.

GBA Games
In the GBA Games, the stat caps for unpromoted characters are 40 in HP, 30 in Luck, and 20 in Strength, Magic, Skill, Speed, Defense, and Resistance. Once promoted the stat caps are higher, with 60 for HP, 30 for luck, and numbers that vary between class and gender for other stats.
