Individuals are born with mana, which accounts for their life force and has a hand in determining the strength of their spells. Mana level and composition is determined by a person's genes, which they inherit from a mix of their parents. There are three factors that decide magical power:
- Maximum reserve: This describes the level of reserves that a person contains. Individuals with extremely high mana reserves represent the strongest of witches, and can access the most powerful spells in mage craft. However, they have more difficulty in controlling and directing the flow of their mana. As a result, their spells take longer to perform. They also have a slow recharge rate, lengthening the time period between spells.
- Focus rate: This describes the level of control a person has over their mana flow. Individuals high in this category have small reserves of mana, and can be considered weaker than average. However, they have much more control, allowing them to be more precise and direct. While those with high reserves are battering rams, they are a scalpel. They also have slow recharge rates, leading to longer intervals between spells.
- Recharge rate: This is the category that most people fall into. They have average reserves of mana, as well as typical levels of control over it. They have a higher rate of recovery, allowing them to recharge their mana quicker than the other categories.
