New Writer Needs Feedback on Power system.

I was thinking of a power system that was inspired by Avatar the last airbender and Hunter x Hunter's Nen system. I would have 8 Elements the characters the characters were born with and be able to speck into a secondary element later on from the list below:

Fire

Water

Air

Earth

Grass

Electric

Light

Dark

However, in each element, the characters would utilize them using something similar to Aura in which there would be:

Enhancement - Strengthens oneself or things

Transmutation - Changes the quality of aura to something else

Emission - Detaches aura from self

Manipulation - Ability to control animate or inanimate objects

Conjuration - Creates Physical objects from Aura

Specialization* - Can utilize the other aura types at full capacity however you are only able to use one element.

Also like in HxH, characters would be able to speck into another aura type at a reduced efficiency.

Using this system I believe I would be able to explain a lot wacky powers. Luffy from One Piece, the stands from Jojo, the summons from Naruto and Ki blasts from Dragon Ball all could be explained in my system.

Example 1.

Luffy would be a grass type Enhancer as rubber is sourced from trees and he would enhance his body to simulate it's rubber like qualities.

Example 2

The stands from Jojo could be any element transmuted from the user's aura to create a stand that helps the user fight.

Example 3

Goku's Kamehameha, in my system it would be an electric emission ability.

Example 4

Sung Jin Woo from Solo Leveling would be a dark type manipulator

Example 5

Gilgamesh from the Fate series would be an Earth Conjuror that heavily uses Emission

Special note for Specialists:

A specialist would be to all that was mentioned before more powerful than a regular user at the cost of being limited to only using one element. So, a fire type specialist would be at a disadvantage against a water user but could win using strategy.

I thought a lot about this but if it's flawed let me know. I've never really written before and could use the help or the criticism. If it's considered plagiarism, then I might just give up on this idea.
