Death City, home of the Death Weapon Meister Academy (DWMA), is the breeding grounds for the world's most proficient meisters. In the never ending fight to collect souls of those that manipulate and spread madness throughout the world.

Soul Perception

Starting at 3rd level, you gain the ability to perceive the souls of those around you, as a Bonus Action you can gaze at a target revealing their Soul and its aura to you and all others in Soul Resonance with you.

Souls take the form of a burning sphere in the center of a creatures chest, they have an aura around them that is larger the stronger they are.
The aura of a weak soul is too small to be seen, but a demigods would be large enough to encircle a city.
The size of a player characters soul will scale with their level and other strengths, for every level a character has their Soul aura size increases by roughly half a foot in radius.

The soul of someone who has taken the life of another is unmistakable, as well as if they have absorbed the soul of another being, the souls initial color is based upon Alignment, Blue when Good, Silver when Neutral, and Grey when Evil, and changes based upon the number and severity of the sins committed which tinge their soul red, eventually becoming closer to black, but almost never completely.

In addition, you can see all souls that are not attached to a body or vessel passively without the need of a Bonus Action.
