The Boys of Silence Grenade is a high-detail, steampunk-inspired explosive device with Art Deco influences, featuring a cylindrical brass body with intricate engravings and gears visible through small glass panels. The top is adorned with a stylized, menacing face reminiscent of the Boys of Silence, with glowing red eyes that intensify when activated. The grenade emits a faint humming sound and a pulsating red light, indicating its unstable nature.
