Description
Magical Powers are mysterious abilities invoked through unknown means. The source of an individual's power is stated to be drawn from one's will, beliefs, and experience. The power resides within the body itself even though the catalyst to awaken one's power is unknown, the former being supported by the Holy Knights' beliefs that their bodies are imbued with "magic that transcends human knowledge." Magical powers can also be gained and utilized from other sources of power by research and experimentation. There are times when powers are inherited.

A magical power weakens and grows unstable if the user loses control of their emotions, though this may be remedied through training. Magical abilities can be sensed through the exertion of the individuals' auras and those who felt it have different reactions towards such level of power. They can be measured by Balor's Magical Eye by Power, Strength, and Spirit in numerical values that determine one's overall Power Level. While powers grant users various advantages and benefits when engaged in combat, there are drawbacks for using them: For example, Full Counter's inability to reflect indirect or normal attacks; Ruin's ability requires a unique staff's bell to make it work; and Invasion's requirement of a long-range distance.

These abilities can be categorized into offensive, defensive and support skills in battle. The Holy Knights from different kingdoms across Britannia use their magical abilities to protect the people from various threats in their lands.
