In normal cases, mana could be increased through various things. The most growth period will be when someone reaches adulthood or just breakthroughs their grade. During this period, people's mana grows naturally even if they don't do anything.

Besides these particular periods, mana-refining meditation training is the other most common method. Most people will use this method to increase their mana every day.

However, this method will only increase mana incredibly small, especially for high-grade people. If mana is calculated based on Angus system point, it may only increase up to five points by meditating for one whole year.

The increase will become smaller as the grade becomes higher. Another method is experiencing a harsh battle and pushing themselves to the limit. It is a risky method since one wrong move may end up losing one's life.
