A deadly condition where the victim’s magical potential keeps rising, faster than the body can keep up with, resulting in death within weeks to months.

Prevalence: Extremely rare (1:100,000)
Lethality: 100% guaranteed (estimated 3 weeks to 3 months)
Description
A rare and extremely dangerous condition which results in the body accumulating magilite at an exponentially increasing pace, quickly leading to severe cell damage and organ failure as the body can’t keep up with the amount of energy.
The cause is currently unknown, but researchers are heavily interested in studying the disease for its potential ramifications when it comes to magical amplification techniques (i.e. methods to increase magical potential)
The rapid physical decline can be slowed down by rigorous and consistent use of magic. This however, is only achievable if you have awakened your magic; regular people diagnosed with mana buildup syndrome are unable to exhaust their magical potential, and quickly succumb to the disease.
Symptoms
The first symptoms are frequent nose bleeds and a heavy physical feeling. This happens as the body struggles to adapt to the amount of energy that keeps accumulating in the body.
This symptom is similar to the primary symptom of mana overload, as the brain and surrounding tissues start breaking down from the energy coursing through the magicampal pathways.

After the first few weeks, a sharp decline in cognitive abilities becomes evident, as the brain becomes more and more damaged by the amount of energy coursing through the magicampal pathways.
Around week three or four is when most people die, when their brain stops working and their organs start shutting down.
Mechanism
In healthy individuals, as the body recognizes that its magical potential is exhausted, it starts absorbing more of it out of the air, water, and food, stopping once the levels reach a certain baseline (determined partly by genetics).
In individuals with mana buildup syndrome, paradoxically, as more magilite accumulates in the body, the body starts working harder and harder to accumulate more and more, resulting in a rapid increase in the victim’s magical potential.
While an increase in magical potential sounds great in theory, in practice, the body can only support so much magilite before its volatile and energetic nature starts tearing down the surrounding cells.
With training, it’s possible to increase the bodily tolerance for magilite, but that takes years; the speed of the change is what kills you with mana buildup syndrome
Misc
A famous sufferer of the disease is the former doctor turned Elite Soldier, Arian Ruger.
