Every mortal has a life energy inside them called Flow. Living beings can manifest their life energy to cast out abilities from their bodies to the world.
Individuals utilize these powers in many different ways; some might be similar or the same as the previous Flow users, like two people who can use fire as the source of the Flow.
They might have the same powers, depending on their use. Let's say one user is casting fire from their hands, but the other is creating fire from their feet. Not a single Flow releases the same, even if their abilities are the same.
Flow doesn't resist simultaneously using different types of magic, like ice and water. However, the flow will drain quickly, making it risky for most to expand their unique powers.
The Three Basic Flow Techniques are the only ones that would not drown your Flow quickly by using different types of Flow.
These three basic techniques are,
1. Sight — an individual who can feel the presence of danger before it happens.
2. Teleportation — an individual who can freely teleport places they visited.
3. Telepathy — an individual who can communicate with another individual with their mind. Both parties need to have telepathy to work.
As their name suggests, these are the basics beginner Flow users can learn before they find their unique Flow abilities. Skilled Flow users master these basics with their powers, making them strong and difficult to beat!
If Flow reaches zero, an individual must wait for it to recharge again to cast abilities or consume any solid or liquid that the life source goes above 0. (e.g., Alucard's consent consumption of blood to activate his blood techniques.)
Many flow techniques have a final ability of a person called Ultimates. An individual needs to yell the Ultimate's name to activate the power. It would only start if it did that.
Ultimates consume lots of Flow from getting triggered. Sometimes, it may empty fully charged life energy, so people need to think about when to use it.
Ultimates can change by unlocking new and more powerful abilities by training, and their perverse ultimates become their regular techniques. They might become weaker than before, but they wouldn't drown an individual's energy or need to yell to trigger it.
Some people can't use their Flow energy because it's locked inside their body, so they must first unlock it by training before using it. How do you train, you may ask?
There are teachers and masters worldwide who would help someone open their locked powers.
Or if they don't learn with teachers, they train themselves, but it's much harder to do that, so people choose the latter.
That's just for unlocking their life energy to use them. After that, individuals need to train harder to use their powers property. It would take a very long time to open Flow and master it.
If you want to avoid going through training Flow completely, there is an alternative called Flow Weapons.
They are weapons that Flow Energy makes into solid objects. They can cast powers out like any Flow users. But most of the time, the weapon holders are weaker than those who unlocked it.
Because the individual is not using their life source but instead fake Flow from the labs from science experiments or someone else's source, it is much weaker than when they used their Flow. Weapon holders also need to train to unlock their full potential.
Few Flow weapon holders are stronger than most skilled Flow users.
These are a few examples: Excalibur Clockwork, Durandal of the North, Merlin, etc. These guys can defeat most of the skilled Flow users.
Flow is a very ancient source of power that the God of Creation left after he created the worlds, gifting the mortals these special life energies who can cast abilities from their bodies.
These powers shaped every world's nature, culture, beliefs, people, animals, and development. So, yeah. Flow energy is very important!
