Mage Knight

Mage knights (or spellswords) are mages (or knights) who one day decide they want to walk a mile in the others' shoes, realize their previous experience plus their new found abilities or equipment or training, depending on the setting make them formidable opponents.

Downsides of this career path

Nearly all settings have some form of rule saying that magic doesn't work while the caster is wearing armor. Although being a spellsword (mageknight) does lessen the effect, don't expect to be slinging meteors around. Really, instead of an even half-and-half of wizard and warrior, they usually end up being fighters with some cool little tricks.

Mage knights most commonly have some stupid sword made of crystal so they can focus their magic in it or some shit. They also ride dragons a lot which is retarded... how exactly are you supposed to use that rare-ass, badass sword while on the back of a beast so large you'd have to fucking keep your legs around its neck just to hit anyone?
