Core Concept:
In this world, every person is born with a Mana Core a crystal-like organ in the center of their body that absorbs and stores aether (the energy of the world). This Core determines how powerful a person can become.
The Core grows with experience, training, and battle. It grants unique abilities based on its Type, and the stronger it becomes, the more powerful those abilities get.

Broken Cores & Evolutions:
Some people are born with Broken Cores damaged or unusable.
But if trained carefully, Broken Cores can evolve into Void Cores, which defy logic.
Example: A Broken Core user unlocks the Void Core, gaining powers over nothingness, erasure, or teleportation.
Absolutely. Here's a domain expansion concept designed to work with your Corecraft system, styled similarly to Jujutsu Kaisen ritualistic, reality-altering, and deeply tied to the user's skills and mentality.

Domain Expansion in Corecraft
What Is It?
A Domain Expansion is the peak expression of a person's Core a supernatural space where the user becomes an absolute authority. Within this sealed territory, their skills, rules, and will override natural law.
Only the most advanced Core wielders (usually at Legendary Level and above) can activate it. Creating one requires not just power, but a complete understanding of one's identity, fighting style, and Core nature.
It is not just a technique it's a manifestation of the soul.
---
How It Works:
A user channels every drop of mana from their Core to form a Boundary, often through a chant or instinctive Some people with large amounts of mana don't have to use all of it.
The domain creates a world that mirrors the user's deepest mindset, battle instinct, and Core affinity.
Inside, the user's attacks always land unless countered by a stronger domain or escape technique.
The environment itself becomes a weapon terrain, weather, gravity, perception all bend to the user's theme.
---
Domain Traits:
1. Territorial Control – The caster decides everything: space, pressure, visibility, time flow (minor), and elemental behavior.
2. Auto-Hit Rule – Every skill used within a Domain "strikes true" unless countered by a barrier, domain, or special resistance.
3. Core-Linked Reality – The domain reflects the user's core type, personal trauma, ambitions, or fighting belief.
(Example: A user obsessed with protection might create an indestructible fortress domain.)
4. Mental Cost – Maintaining a Domain is mentally and physically exhausting. Some may only last minutes. Overuse can crack or shatter the Core.
---
Opening a Domain:
The expansion begins with a surge of mana as the user declares their Domain either with a spoken phrase.High Rankers can do it silently. This declaration often matches their fighting style or inner self.
Examples:
"Within this circle, only I write the law."
Domain Expansion: Sovereign Script
"All things must end… by my hand."
Domain Expansion: Endbringer's Grasp
"This is my world and your grave."
Domain Expansion: Monarchs Endgame
A mark may appear underfoot circles, sigils, glyphs or the world may simply bend, like a dream becoming real.
Everyone has a different Domain Expansion.But some domains are passed down through families or legacies.
---
Counterplay:
Domain Clash – If two users activate Domains at once, the stronger soul or Core wins and overwrites the other.
Simple Domain – A lower version that blocks auto-hit effects, used for defense.
Domain Breach - Rare skills allow breaking into or out of domains but they're risky.
