Black Mages
The Final Fantasy video games series, especially installments focusing on a medieval/sword-and-sorcery setting, previously based their battle system about the concept of job classes. Each class has certain abilities assigned to it, thus playing into certain classic fantasy roles, like tank, healer, buffer, etc. The Black Mage is your solid offensive caster type.
Depsite low health points and poor physical defense, the black mage excels in battle due to providing your strongest magical spells. Most abilities are elemental attack, though there are other types of spells. Stylistically, the black mage traditionally wore a blue robe with a yellow pointy hat. It has become one of the most recognizable symbols in the Final Fantasy metaseries.
