Flash

Description
A non-lethal grenade used to stun and disorient targets using a blindingt flash of light and a deafeningly loud sound. It works by

activating all photoreceptors in the eyes, making visions impossible for 5 minutes, with the sound temporarily disabling hearing and creating loss of balance by disturbing the fluid in the ear.

Costs 30 coins.

Background
The flashbang, or by its actual name, stun grenade, was first used by the famed British SAS during the 1970s.

Unlike explosive grenades, which are designed to be destroyed upon explosion, nonlethal ones are made to contain most of its explosive force and to avoid damaging its surroundings, and has holes and cutouts to allow the sound and light to pass through.
