Ezio: "I need a simple but effective means of distraction."
Piri: "Then this is the bomb for you. It gives a nice loud burst, luring all soldiers within earshot right to the source. Have fun."
Piri Reis describing a cherry bomb to Ezio, 1511.[src]
Cherry bomb

A typical cherry bomb

Cherry bombs were explosives utilized by Assassins, which detonated with a very loud bang, luring every guard within earshot. Ezio Auditore da Firenze could craft cherry bombs using any shell or gunpowder type combined with the sulfur effect.

If one was detonated in the correct place, it could also be used to create a conflict between Ottoman and Byzantine Templars patrols. As such, the Ottoman Assassins made use of this to great effect in order to create distractions that could cover their infiltration or escape.[1]

The Assassin Arno Dorian used cherry bombs in a similar manner during the late 18th century.[2]
