What Camila Cuevas Said About Bravery
It is the only soul trait that can be divided into both physical and moral aspects.
This trait is usually balanced in each wizard but with the expection of a subject that possesses more or less of one aspect compared to the other.
Physical Bravery resists very well everything that is physical pain, hard work, exhaustion or the possibility of receiving injuries or even death
Moral Bravery allows the people to act correctly despite the dishonor, shame, or social rejection you might get from your decisions
These aspects do not define a wizard’s magic power but it might be an issue for the subject’s magic if it affects them personally. However, this would only happen if the two aspects are not well balanced, but as mentioned earlier, it not very likely to occur.
The soul trait, FEAR is not a new trait, instead, it is an inverted version of Bravery. (Color : dark orange)
Although the FEAR soul is the opposite of the Bravery soul, the Bravery soul can't beat the FEAR soul because Negatives are always stronger than their positive counterpart.
