As RPGs go, Traysia's stats system is extremely simplistic. This page explains what you should know to watch for when buying and equipping items, etc.
Stats screen[edit]
To look at each character's stats, first camp with 
and then choose the party member whose stats you want to view and hit 
. Move the arrow down to the crystal ball and hit again, and you'll get a list of that person's stats. The following is a quick explanation of the stats and what they mean.
If you've played an RPG before, you should be familiar with the two figures at the bottom of the stats screen: Level (LV) and Experience (EXP). Your character's Level is a measure of his or her overall worth and skill. You gain EXP by defeating enemies and accumulating enough will make your character gain another level and become stronger. But the more important parts of the stats screen are attribute-type stats shown above the LV and EXP numbers.
Two column display[edit]
First of all, notice the layout of the stats: two columns. This is because there are really only four attributes for each character, but each is represented two ways in the stats screen. The numbers in the left column are the character's base values for Strength, Defense, Agility, and I.Q. The figures in the right column are these values after adding various bonuses for whatever equipment the character is using. For instance, if a character has a base value of 25 Strength and is using a sword which gives him a 20-point bonus in that area, his Attack Points will be 45. It's simple.
That being said, it's the stats in the right column that are used during the game. The stats in the left column make it easy to see your character's "raw talent" without unequipping all of his or her weapons and armor, but that's about the limit of their usefulness. For all intents and purposes (including this guide), the only stats that count are the ones on the right.
Here are the actual stats, listed by the "base" stat and its corresponding "modified" stat:
- ST/AP (Strength/Attack Points): This determines how powerful physical attacks will be.
- DE/DP (Defense/Defense Points): This determines how successful your character will be in reducing damage and blocking attacks altogether.
- AG/SP (Agility/Speed Points): This determines the order in which the character will act in battle.
- IQ/IP (I.Q./Intelligence Points): This determines how effective magic spells will be.
