Exploding rock



The exploding rock random event happens when a player tries to mine a rock at which point it begins to "steam/smoke/bubble". After mining that rock for a while, the rock will explode, which will break the player's pickaxe (see broken pickaxe), making it unusable, and will also damage the player for up to 10 hitpoints. Pickaxes can be fixed by Nurmof in the dwarven mines and at Bob's Brilliant Axes in south Lumbridge (for a price of course; the price gets higher the higher level required to use the pickaxe). However, bronze, iron, and steel pickaxes can be repaired for no cost. This event was created to ward off bots by Jagex. It is one of the many counter-bot measures they have placed on activities that require long work, like fishing and woodcutting.
