Power... it draws its source from one's strong will, belief and experience.
— Dreyfus in Chapter 66.
A Magical Power「魔力, Maryoku」 is a mysterious and supernatural ability that allow its wielder to perform various techniques. Generally, it is unique to individuals.
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 experiences. 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.
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 people from various threats.
Everyone has their own unique magical power, though some powers can be shared by more than one person, such as the case with Gustaf and his sister Jericho. Some races have magical powers that are shared across their races population, though individuals would still have their own individual magical powers. In some cases, powers can even be taught to others, such as how Chandler taught Meliodas how to use Full Counter.
A persons magical power can also be measured as a numerical value by Balor's Magical Eye, along with Physical Strength and Willpower. These three factors, when added together, determine one's overall Power Level. Magical abilities can also be sensed through the exertion of the individuals' auras and those who felt it have different reactions towards such levels of power.
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.
As explained by Pellegarde, there are different Magical Power Types「魔力の型, Maryoku no Kata」  by which abilities fall into one of nine categories. There are very rare instances of a person possessing two or more types of magic. Few cases among these people possesses four or more types of magic. Such people are called Hero-Types.
