Talents are special character , we can say skills , which give some type of advantage , can be statistic increase or other stuff like valor received increase etc.
First of all to get a talent are required some things to unlock these talents :
1. Specific level : you can check in your inventory , combat skills , then talents section , there are many unlockable with levelling up.
2. Valor : there are talents which can only be unlocked once you reach a certain valor rank.
3. Books : there are talents which can be only obtained if you get the special talent book.
The player can also level up specific talents by getting a certain ammount of Crystal of Truth (

There are all the possible talents :
1.Talent that increase certain stat like : protection , intuition or agility.
2.Talent that increase the trauma and the antitrauma.
3.Talent that increase the speed or initiative or durability.
