your Lovely author thought of introducing an energy scaling system as it would be easier to explain things.
ENERGY POINTS is the type of energy scaling system based on the number of photons a human body produces.
> 1 energy point is the amount of energy required to activate a normal skill ( just activating though using the skill takes extra energy )
different types of skills different amounts of energy points to activate.
1) normal skill = 1 energy point.
2) rare skill = 2 energy points.
3) unique skill = 5 energy points.
4) legendary skill = 10 energy points.
there are methods to increase efficiency or attack power made to utilize fewer energy points and do more attacks or work.
> ' energy circulation ' everyone can learn this method but needs the practice to do so but only maki and kali know about this method until now. ( refer to chapter 14 for more information )
> ' photon destruction ' and ' electromagnetic addition ' only for kin who has the birth relic ' pupil of infinite lines '. ( refer to chapter number 20 for more information )
> ' energy compression ' it's the same as ' energy circulation ' shadow lord and Sudheer know about this method until now.
> ' photon fusion ' and ' electromagnetic attack charge ' Raj and Sudheer know about this method
there are other methods but they will be updated once revealed in chapters.
