Black Smoke Gunlance

Darkness-infused Gunlance. The black smoke it gives off is mesmerizing. Shelling Lv1
A cursed gunlance that makes everyone who sees it think of a "dark power". The writhing shaft, as if the Black Dragon's form had been taken in whole, has the Black Dragon's evil eye set into it. It is whispered that anyone who sees the light that eye gives off when Wyvern's Fire is unleashed has the strength drained from their body against their will.
