AkantorNoirGunlance

The black flames that spew forth char the soul as dark as night. Shelling Lv4
A gunlance that hunters revere as "holding the soul of the 'Black God'". The red lines running from the shelling mechanism to the tip are said to rumble as if light were racing along them when Wyvern's Fire is unleashed, a sight that calls to mind the heroic form of Akantor.
