SoulBound Energy

Origin
Mobians with a SoulBound (SB) power have a specially modified soul that constantly generates the energy, which is then eaten whenever said user uses their respective power.

Uses
SoulBound energy can be used to fuel a power conventionally. Other uses include harnessing it as a power source and using it as actual energy.

Strengths
Users can, over time, relieve one weakness by adapting their strengths to that type. (E.I. Lee is a tech type who uses SB energy.)

As the energy is aligned with life and light, Umbrakinetics are weak to this energy if used correctly; used incorrectly, and the darkness wins.

Weaknesses
There isn't really a set weakness; it variates from user to user. Consistent weaknesses however, are Umbrakinetics and Death Types.
