The Skull is a simple reskin of the Rock item, a default blueprint known to all players and the starting weapon of all nakeds spawning on every beach. It is one of the Wood and Ore gathering tools in RUST. It requires no fuel to operate but takes consistent durability loss while being used to hit trees, nodes, or any other entity.
It is the bottom-of-the-barrel option for gathering any resource and is promptly replaced by the Stone Hatchet and Stone Pickaxe. The tradeoff is the need to carry 1 tool instead of 2.
While Rocks aren’t found in any crate or barrel nor looted from any vanilla NPC, they are quite common mainstays and often very handy in a pinch. Raiders looking for materials to seal a base or gather wood commonly attempt to find ground stone pickups to craft a Rock.
Using a Rock as a melee weapon is quite normal, but they break very fast due to their limited durability. Its unique blunt impact damage type also means it can damage metal doors, if only slightly. It is the perfect tool for finishing a Sheet Metal Door’s last 1-2 health points. It is not recommended for use with either gathering tea due to its limited resource-gathering capacity.
