Just some fun with the Guillotine gun during assassinations. The weapon does damage to enemies within an aiming radius. It's like combining the Blunderbuss with poison bombs.
The range on it is like with tools because of how the gun is aimed. From a height you can shoot even further. The combat kill animations are the same as an ax. Low level enemies are killed instantly by it's fire, while most high level ones can take two or three hits.
