Brave is a measure of battle prowess. Units with high Brave tend to have more powerful and accurate attacks. It also improves some defensive skills.

Units with low Brave have attacks that are less powerful and accurate. Also units with a Brave of 10 or below turn into a chicken and retreat to a corner of the battlefiled.

The only advantage to low brave is it improves your odds of finding a rare treasure by Move-Find. Subtract a unit's Brave from 100% to calculate the odds.

Faith is a measurement of how spiritual characters are. Characters with high Faith tend to do more damage with attack spells and heal for more with curative magic. They also receive more damage from spells directed at them.

Characters with a Faith of 0 are Innocent and spells won't affect them at all. The Steel Giants are always Innocent.

The tricky thing is to avoid lowering the Brave of any character other than Ramza below 5, since they tend to leave your party. The same is true of characters with a Faith above 95.
