Magic and Objects

When Tessia get's her body back, was her core reformed or did she form a new one? Tessia having integration and a white mana core makes more sense, but it implies too much.

Wouldn't Tessia reaching integration twice possibly kill her, or would she have to become stronger to integrate twice? Would her body allow her to integrate twice? If she can't integrate twice due to being a lesser, could she have two beast wills? Lastly, since mana core's aren't just made of mana, and when a core is shattered, it stays in the body, if Tessia's core cracked or shattered, would it be integrated or be repaired?

Hey, so I'm trying to write a fun fanfiction, but I want to include the integration stage into it as a big role. does anyone know anymore about it, or am I best just taking a shot in the dark? (also, would it be possible to purify mana before forming it into a core? technically, Arthur skipped a big step by pulling the mana together to form a core, and cores are dark because of blood/impurities in the mana, so what if one just made sure there were no impurities before forming the core?)

Water -> Ice (molecules are slowed down prevents friction and heat therefore it cools down.)

Earth -> Gravity (the mana in the air forms into the "rigid" earth quality and the mana turns heavy. making gravity)

Earth -> Metal (maybe dwarfs have insane control over earth and can control the small impurities in metal)

Earth + Fire -> Magma (magma is molten earth, basically just a different form of earth)

Water + Earth -> Plant (like how humans have healers(which i assume is accelerating the mana in the meridans which fuel the body's energy), elves basically use the same understanding and speed up the growth process of plants at high speeds.)

Air -> Sound (vibrating the air molecules into a tuned sound)

Healing Magic -> (accelerating the mana in the meridans(mentioned when Arthur had a mock battle against that one guy in Tess's squad.) which circulate mana through the body healing small wounds and getting rid of impurites. what healing does is: accelerating that process. speed up the mana flow.)

but how does fire turn into lighting? maybe...theory btw:(the radio waves, gamma rays, and X-rays, are forcefully separated for a fraction of a second and they slam back together creating a lot of friction which ignites the air, creating lightning)
