Mining accumulator detail.png

The mining accumulator is an Invention device that gains charges whenever the player lands a critical strike whilst Mining. When it reaches 100% completion, it can be studied for 2,500 Mining experience, which destroys the accumulator. If Mining accumulators are bought on the Grand Exchange, this gives them a cost of 20.09 coins/XP.

Using this device requires the completion of the Invention Tutorial and a charged Charge pack. Discovering this device requires the player to have the blueprint unlocked from the Dwarven technology tree, and level 50 Invention. To unlock a blueprint in a tier, at least one blueprint in the previous tier must be unlocked (though it doesn't have to be researched). Success in creating the blueprints earns 18,257 Invention experience.

If auto-teleporting urns is toggled on, the accumulator is automatically studied when filled.
