Smoke Rapier

Piece created in 2022 for Sword-tember with the prompt of Smoke.
The blade is ideal for an assassin or dexterity based wielder, as rapiers are light for piercing thrusts rather than slashing, and its ability to produce endless amounts of smoke allows for stealth opportunities.
As visible in the WIP, the smoke was original going to be the standard type, but after playing around with some filters the rainbow hues emerged which are reminiscent of that oil-on-water sheen, which a magical concealing smoke may be like, sticky and cloying.
