When mining runite, players may find it useful to keep track of the time that they mined the ore, as well as the world number and population. If done accurately, players can hop to other worlds (keeping more notes along the way) to mine runite while keeping an eye on the time, and then hop back to worlds where they previously mined runite when it is about time for the ore to respawn. This method of collecting runite ore only applies when mining in popular areas like the Keldagrim north mine. Runite rocks in places like the Lava Maze Dungeon mine are rarely targeted by players, and as such there is little need to worry about the ore being gone. However, such places are usually dangerous.
