Mana Drain Sickness.
Or MDS, as most people liked to call it.
It was one of those common mana-related conditions you'd hear about from time to time.
The kind you got when you overused your mana reserves and pushed yourself past the safe limit of your core.
Nothing new.
Plenty of mages suffered from it, especially those who didn't know when to stop.
The basic explanation?
When your mana output exceeds the overlapping threshold of your core—either from reckless overcasting or stress during combat—your core gets overworked.
And when that happens, it starts breaking down, slowly frying itself from the inside out.
But the good news? It was treatable.
Usually, you'd just chug a few mana potions, maybe lie down for a day or two, and you'd be back on your feet.
In more serious cases, a few divine healing spells from a church priest or a skilled healer could patch you up clean. That's how it normally went.
But Stacia's case… wasn't normal.
