#Intro Hey everyone! A while back, waaaaaay back last year I think, I posted a magic system here (or on another sub, check my history if you're curious). Honestly? Looking back, it was a bit too rigid and isolated. It had physics-related domains (Kinetic Dynamics, Molecular Engineering, Fluid Dynamics, and Atomic Architecture), but I lost interest because I hadn’t defined the fundamental metric of a being's magical structure.

I wanted to fix that. It's mostly based on a hard magic style so I wanted levelling up to feel more like engineering. Or whatever it is I'm doing.

So, here is the evaluation metrics or parameters that I think can decide the value of a mage.

The 5 Core Parameters for Evaluation:

1. Mana Capacity (The Energy Density)

In physics terms, this is the Potential Energy stored within the body in either any form you decide; a core, stars, circles.

The Hard Logic: An expert mage wouldn't just have a "bigger battery"; maybe the would compress mana without it undergoing some sort of "phase transition" (like turning into heat and cooking their internal organs, or even ripping their core apart).

The Upper Limit: At extreme levels, high capacity might create localized gravitational pulling or spatial warping. Well subject to discussion cause I dunno. An explosion perhaps?

Example test: The Drainage Test. A mage is tasked with charging a standard, high-capacity magical crystal from empty to full in a single sitting. The metric is simply how much total energy they can pour into it before running completely dry.

2. Mana Circuitry / Conductance (The Throughput)

This is the Ohm’s Law of the system I = V/R.

The Hard Logic: Conductance determines how much energy can be moved from the "battery" to the "spell" per second (Power, in Watts). Or any other mana units you decide. I think I wanna decide this next.

The Bottleneck (Joule Heating): Just like a copper wire gets hot when overloaded, a mage with high capacity but low conductance would essentially rip their internal pathways if they try to cast a high-tier spell too quickly.

Example Test: The Burst Test. The mage must release a specific amount of energy as fast as possible (e.g., lighting a massive bonfire instantly). The test measures the speed of output versus how much physical strain, pain, or internal "burn" the mage experiences from the sudden rush.

3. Mana Control (The Vector Precision)

Think of this as Signal Processing and PID Control.

The Hard Logic: If a spell is a wave, Control is the ability to maintain frequency and amplitude. High control allows for "Constructive Interference" (doubling a spell's power by overlapping mana waves perfectly).

The Failure State: Entropy. Without control, mana leaks into the environment as waste heat... or static. i.e. inefficient. Would have to have some sort of change during casting, so maybe just wastes mana in itself.

Example Test: The Shape-Holding Test. The mage must manifest their magic into a perfectly static, intricate shape—like a floating, seamless cube or ring—and hold it perfectly still for ten minutes while external distractions (like minor physical impacts or loud noises) try to disrupt their focus.

4. Mana Purity (The Signal-to-Noise Ratio)

This is Coherence (think Laser vs. Lightbulb).

The Hard Logic: Impure mana may contain conflicting frequencies. Pure mana is monochromatic and coherent. A laser can cut through steel with a fraction of the energy a heat lamp uses because the energy is perfectly aligned. This is where you could probably personalize mana, like bloodline related, soul related, astrology could play a big game here.

The Upper Limit: High purity allows for "Superfluidity," where mana flows with zero viscosity, creating spells that would never lose momentum.

Example Test: The Filter Test. The mage tries to pass their magic through a naturally resistant or "grounding" material (like dense lead, cold iron, or a anti-magic field). Highly pure, coherent magic pierces straight through with minimal loss, while impure magic scatters and diffuses.

5. Spell Formulation (Algorithmic Complexity)

If the other traits are hardware, this is the Software/Physics Engine.

The Hard Logic: To create a fireball, a mage doesn't just "wish" for fire. They could formulate a mathematical field that excites local oxygen molecules while simultaneously creating a containment gradient. There could be endless amounts of interpretations unique to your magic system... I know mine will... hehe.

The Limit: Cognitive Load. Complex spells require solving differential equations in real-time. This is why I view "chants" or "circles" as externalized, pre-compiled code blocks to keep the mage's brain from crashing. The compiler or the "Assembly Language" would probably be decided by a deity or any other force that made mana usable perhaps... Perhaps 'nods'.

Example Test: The Adaptation Test. The mage is given a complex spell script they have never seen before and must cast it flawlessly on the first try, or they are forced to dynamically alter an active spell mid-cast to adapt to a sudden change in environmental conditions (like a sudden downpour of rain).

Future Work

I still have yet to decide how to go about other constraints but I'll give you guys that leeway to do, suggest it or keep it to yourself up to you.

This is in the Work-In-Progress phase... So in the future, I might decide to:

• Define a Unit of Mana: Hooking it into standard physics by referring to Joules, or creating a custom unit for work done per second.
• Recovery Phases & Techniques: How does a "drained battery" recharge? Does it pull ambient mana from the air, or rely on biological rest?
• Efficiency Limits: Can a mage ever reach 100% efficiency, or would they will always emit waste? Following the second law of thermodynamocs.
• Species-Specific Biological Hardware: How would different species naturally scale on this metric? For example, do Elves have built-in "superconductive" pathways (high Conductance), while Dwarves act like heavy-duty capacitors (high Capacity but lower Control)?

DISCLAIMER: For the record, I'm not an engineer but I love, love, love magic with some physics coded into it. So... Me, myself and 8th Grade syndrome?
