The magic used in this series is largely "soft," though there are more complex branches, such as summoning and more advanced spells. The general rule is that mana powers magical energy, but skill is just as important.
One of the running gags is that despite not being a mage herself, Anniken is able to perform basic spells with an ease Meike lacks—at least in the beginning. The skill level between the two widens as Meike fine tunes their abilities.
However, lower mana stores and high cost spells can limit a mage on the battlefield and tire them over time. Even with the use of potions, fatigue is a major concern.
