・Being assigned to the Guild Barracks (maximum 70).
・Picking up a Crystal dropped by killed enemies during battle (maximum 97).
・Certain abilities such as Meditation (maximum 97).
If Bravery of a unit is 9 or lower, that unit becomes Chicken in battle. A chicken unit takes more damage and moves to avoid enemy units. You can't control it.
During battle, a Chicken unit regains 1 Bravery each turn and is cured once it's Bravery reaches 10.
What is Faith?
Faith affects the followings:
・The amount of magic damage that a unit inflicts and takes.
・The amount of HP restored by abilities.
・The chance of activating a reaction ability when attacked by a magic attack.
・The chance of being afflicted or afflicting status effects.
How to Raise Faith
Faith can be increased by:
・The effect of abilities like Cheer and Final Hour (Final Hour's effect lasts only in the battle that ability is used) (maximum 97).
・The Guild Barracks (maximum 70 - not yet implemented in GL).
On the Global server placing a unit in the barracks lowers faith. On the Japanese server, when placing units on the barracks, you can select to raise or lower faith; this selection will be implemented in the global server at a later date.
・25% of the amount of Bravery/Faith raised or lowered during battle will be carried over.
・Changes in multi-player quests won't be carried over.
・The amount of raised or lowered Bravery/Faith by abilities such as Final Hour won't be carried over since that ability has turn restrictions.
Basically, a unit in the front lines with physical attacks should have high Bravery and low Faith. It can then deal more physical damage, have a higher chance of activating reaction abilities, and take less magic damage.
However, if you want that unit to gain more HP from healing abilities, it should have high Faith.
A unit in the back lines with magical attacks should have high Bravery and high Faith. Then it will deal more damage with magic-type abilities.
Abilities such as Divine Healing and Chakra are physical, but the amount of restored HP depends on Faith of the caster and target.
