…Crap. I meant to have that in the Mana Poisoning FAQ itself, but it looks like I forgot it. Let me fix that and add a link to this post.
There are five stages of acute mana poisoning.
- Stage 1: The mage begins to feel vaguely ill. Nausea, abdominal cramps, malaise, and slowed reaction times soon follow.
- Stage 2: Now the mage starts having difficulty concentrating on complex and unfamiliar tasks. Adept and Mastered spells lose one training level and spells at Novice level are inaccessible.
- Stage 3: Enough toxic byproducts have built up that the mage develops mild confusion. Close allies and hated enemies are still identifiable, but new faces may blur together, and information may be misinterpreted, leading to bad decisions.
- Stage 4: Tunnel vision and more profound confusion set in. Only the most routine of tasks are unaffected. Previously mastered spells are only accessible at novice levels, and other spells cannot be used at all.
- Stage 5: The most severe stage of mana poisoning. The Linker Core is now so far damaged that it cannot heal itself, and instead it continues to pump out lethal metabolites that cause multi-system organ failure. This stage is invariably fatal within 24 hours, with the mage generally falling into a coma shortly after reaching crossing this threshold.
Stages 1 through 4 will resolve on their own as the liver and kidneys process the toxins produced by the damaged Linker Core, though this requires almost complete abstinence in regards to spellcasting and later stages take longer to resolve. Should magic continued to be used, mana poisoning will persist or even worsen if high-intensity casting is not curtailed. Advanced societies have treatments and medications that decrease recovery time, though even these are limited to a small number of high-level hospitals.
Should mana poisoning become chronic, the mage will become more tolerant to intense mana influxes, but she will develop other severe health issues, including a compromised immune system, autoimmune diseases, malignancies, or even permanent magical crippling. Individuals who develop chronic mana poisoning have moderately to severely decreased life expectancies.
