ninjartist 

A person who not only excels in the arts, but also has the stealth and the combat skills of a ninja.

There are two general classes of ninjartists: those of performance ninjartistry and those of visual ninjartistry. There tend to be more of the latter. For example, instrumental ninjartists use paralyzing music and the instrument itself in combat, while paint-oriented ninjartists use brushes and poisonous paints to defeat their enemies.

Variants: ninjartistry, ninjartists, ninjartistic, ninjartistically

The ninjartist stealthily slit her opponent's throat with a clay knife.

The ninjartist shot the poisoned bow from his cello and struck his opponent right in the heart.
