In his fight against supernatural threats, John Constantine uses a variety of tools and weapons, many of which are supplied by Beeman.
Chain of Religious Symbols[]
During his exorcism at the beginning of the movie, John holds several symbols to the window. When a shadow is cast onto the face of the demon and burn it, he knows what kind of demon it is.
Holy Water Ampoules[]
Glass spheres filled with holy water from The River of Jordan. They have the same effects as normal holy water. They burn the skin off of half-demons. Constantine also used one of these as a conduit to get himself out of Hell by breaking it against his chest.
Screech Beetles[]
A matchbox filled with screech beetles, the sound causes excruciating pain to a Half-Breed. Constantine uses it to repel the Vermin Man.
Dragon's Breath[]
A gold tube that discharges a bright purple flame. According to Beeman it is apparently rare and difficult to obtain. Constantine attaches it under the Holy Shotgun's barrel.
Gold Knuckles[]
Gold plated brass knuckles that are used to fight demons. They have engravings that read "fiat iustitia et pereat mundus", which means "Let justice be done, though the world perish". The brass knuckles have 4 crosses engraved above each finger hole. Overall, they do significant damage to half breeds/demons.
Holy Shotgun[]
After Beeman's death at the hands of Balthazar, Constantine decides to go all out. He assembles the Holy Shotgun (also known as the crucifix shotgun) in Beeman's workplace. The weapon is implied to be a side project off Beeman, with various drawings and parts scattered around his hideout.
The weapon shares some visual similarity to the Streetsweeper shotgun. It has a cross-shaped barrel. with the Dragon's Breath flame thrower at the bottom and a flashlight on top. It has a 12-round replaceable drum magazine. John's apprentice Chas Kramer helps make its slugs by smelting gold from religious symbol, moulding them and putting them in 12-gauge shells.
