I created a power system for my manga concept where your powers come from bonding with a second soul. Thoughts?
I've been developing a manga concept called Spectralbound, and recently I've been trying to flesh out its power system more seriously.
The main source of power is Shin. Certain people can form a bond with beings called Spectres, essentially giving two souls one body.
Depending on how the Spectre manifests, an Occultist belongs to one of four main classes:
Slayer – The Spectre manifests as a weapon.
Magician – The Spectre doesn't physically manifest and the user directly performs techniques.
Outer – The Spectre manifests as a separate humanoid entity that fights alongside the user.
Feral – The user transforms into a creature based on their Spectre.
Every Spectre also has an Affinity. These start relatively simple but can evolve into more abstract concepts at higher tiers.
For example:
Darkness → Void
Space → Multiverse
Gravity → Mass
Blood → Life
Chaos → Entropy
Impossible → Paradox
The part I've been working on most recently is something called Royal Artifacts.
Every Royal Artifact exists only once and disappears after being used. It has a predetermined gift and price, and touching one tells an Occultist exactly what they would gain and lose before they decide whether to use it.
Using one also causes the user and their Spectre to permanently fuse, creating a completely unique class outside the normal four.
One example is an elixir that grants two instant tier increases and immunity to Shin Pressure, but takes away the user's humanity. The resulting fusion becomes a class called Gargoyle.
Another artifact guarantees that the user's greatest wish will eventually be fulfilled, but someone else has to be the person who fulfills it.
I'm trying to make the system increasingly conceptual at higher levels without reaching the point where every ability can just do anything.
Does this feel distinct enough from other battle manga power systems? And which part would you want explained more?
