Paradigm nebuliser
From Tardis Wiki, the free Doctor Who reference
The Lumiat used a paradigm nebuliser to "clear the air" of Missy's manipulations of the atmospheric temperance field in the Sunken Desert. This reversed its effects, causing the combatants in a bloody war to remember that two days before, they had all been strangers, visiting the area to have a picnic. Missy was annoyed that this other woman had stopped her "fun", and presumed she was the Doctor. (AUDIO: The Lumiat)
