- "This code will replicate the combustive effect of the heat and cold gun crossing streams using nanotech. The only thing that's made him flinch so far."

The anti-magic gun is a nanite-based pistol constructed physically by Ray Palmer with a complex technological code to the nanites written by Zari Tomaz. It is made to counteract the dark magic of Damien Darhk and Nora Darhk by simulating the effects of a Heat Gun and a Cold Gun crossing streams.
John Constantine suggested finishing work on it to execute Sara Lance in case she were possessed by Mallus, but it was eventually used by Ray Palmer to shoot Nora when she was about to kill Amaya Jiwe. The effects nearly killed her, but Palmer was able to give a cure to the weapon shortly thereafter.
