Flashbang
A bright explosive device which blinds and disorients anyone near it upon detonation
The Flashbang is a thrown explosive in Rust. It deals 20 blunt damage within 6 m when its fuse of 1.25 seconds runs out. You craft it at a Level 2 Workbench, and its blueprint costs 40 scrap to research.
About the Flashbang
The blast only hurts what it has a clear line to, so solid cover between you and it keeps you out of harm. It leaves your hand at up to 13 m/s.
On the tech tree it sits behind 9 other unlocks: F1 Grenade, Semi-Automatic Pistol, Homemade Landmine, Pump Shotgun, 12 Gauge Buckshot, Metal Shield and 3 more. In all, 23 loot sources drop it; the full list of where it drops gives the chance for each.
Flashbang damage, fuse and blast radius
Anything within 3 m of the blast takes the full damage, which fades to nothing at 6 m.
