Study
'The mana anomaly is a rare condition that can have multiple causes,' Khan read without using the mental technique. 'An excessive purity of the mana, a trauma that involves the mana core, or different mutations can alter the natural azure color and add unwanted features.'
The book went on to explain that the change usually wasn't abrupt. Changing the nature of the mana so radically and permanently was hard even when relying on external methods. Reaching Khan's current state would typically require long months or years of specific procedures. Only traumas could cause something so drastic, but he had merely activated the Wave spell. That didn't sound enough.
'The anomaly can have multiple effects depending on the depths of the changes,' Khan continued to read. 'The different features can affect the normal functioning of the mana or even the user's behavior.'
