Timed Explosive Charge
C4, useful for breaking into bases.
The Timed Explosive Charge is an explosive charge in Rust that sticks to whatever it hits. It deals 550 explosion damage within 4 m when its fuse of 10 seconds runs out. You craft it at a Level 3 Workbench, and its blueprint costs 300 scrap to research.
About the Timed Explosive Charge
From full health, breaking a door takes 1 for the Wooden Door, 1 for the Sheet Metal Door, 2 for the Garage Door and 3 for the Armored Door. For a wall, the count is 1 at Wood, 2 at Stone, 4 at Sheet Metal and 8 at Armored. Broken down to raw materials, one costs 2,200 sulfur, which puts a stone wall at 4,400 sulfur.
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 10 m/s.
On the tech tree it sits behind 8 other unlocks: Explosives, Explosive 5.56 Rifle Ammo, MP5A4, Incendiary 5.56 Rifle Ammo, HV 5.56 Rifle Ammo, Weapon Lasersight and 2 more. In all, 10 loot sources drop it; the full list of where it drops gives the chance for each.
