The Phlogistinator is a primary weapon for the Pyro. It is a retro-futuristic ray gun with some metal parts colored either copper or silver depending on the team, and a team-colored canister stamped with the Dr. Grordbort crest. It fires waves of energy that function identical to the Flamethrower's flames. These energy waves seem to appear across the Pyro's entire range simultaneously, despite the actual damage-causing particles needing a small travel time, resulting in an effect that can be deceiving to the eye.
