Item spawn

An item spawn is an exact location at which a specific item appears at regular intervals, free for any player to take. Although many item spawns are almost useless, some can be quite valuable. Secondary Herblore ingredients are often item spawns, such as snape grass or red spiders' eggs.

Some items are very fast to spawn, such as white berries, but others, like the sapphire spawn in level 46 Wilderness, are very slow. The respawn rate changes depending on the number of players logged into your current world according to the following formula: $\left\lfloor {\text{BaseRate}}{\frac {4000-{\text{Population}}}{4000}}\right\rfloor$, where the ${\text{BaseRate}}$ is the respawn duration on an empty world. If the world is full, the respawn interval is halved.
