The Hellwing Bow is a bow acquired from Shadow Chests found in the Underworld. It converts normal Wooden Arrows into flaming bat projectiles that travel in a semi-straight line and can pierce infinitely. This is countered by the fact that the bats are fired in a ~30° cone and therefore can be very inaccurate at long distances. Other arrows won’t lose their special properties, but will inherit the inaccuracy of the bow.
Its best Modifier is Unreal.
