Mining

Mining is one of the two skills that all players have access to, the other being Woodcutting. Raising this skill allows you to get more drops when you mine, which can be a huge asset when finding diamonds or other rare minerals.

Double Drops
When a player mines, there is a chance that they will receive twice as many drops. This chance is 0.1% for every skill level in mining a player has. A quick and dirty way to check is simply using the command /mining in-game.

Super Breaker
Super Breaker is a Gatherer-specific ability tied to mining. When activated (simply crouch and right-click while holding a pickaxe) the player gets a 100% speed increase and a chance to obtain triple drops. However, while this is activated, the tool will lose twice as much durability.
