Fear bomb

Fear bombs were hallucinogenic bombs developed by the Indian Brotherhood of Assassins. When thrown, the bomb emits a cloud of hallucinogenic powder along with a frightful noise of a scream, causing intense hallucinations and fear among those caught in its wake.

After learning from the Indian Assassins, Evie Frye utilized these bombs in her own missions, including her hunt for Jack the Ripper, who used the weapons as well.
