Light Bow Gun Special Ammo Types
Currently the only special ammo type currently available for LBG is Wyvernblast which are the mines.
The only two special ammo types for HBG are Wyvernsnipe, which is the long piercing shot that explodes; and Wyvernheart, which is the machine gun type ammo.
I have access to the entire weapon tree. The metal tree of HBG is entirely Wyvernheart, the bone tree is entirely Wyvernsnipe. The LBG has Wyvernblast for the entire metal and bone trees.
