Talent is a part of the Synthesis Aspect of the Alloy Fysa. All humans start with this fysa.
This can be either an active or passive fysa. Every user has a unique effect based off their personality and their life experiences. Some examples are fishermen who subtly manipulate the waves, gamblers with high luck, or gardeners with a green thumb. A talent can even go as far as mimicking the effects of other elements-- shooting fire out of a fingertip, filtering fysa out of the air, or changing eye color at will. These should be pretty minor powers though!
