Excavation

Excavation provides a passive ability to dig more blocks and find treasures buried beneath the earth. What you find is based on your skill level and the type of material you are excavating.

Giga Drill Breaker
Right-clicking with a Shovel in hand will activate Giga Drill Breaker.

For a short period of time, it will allow you to instantly break any block that is most effective when broken with a shovel. The duration depends on level and server configuration.

Treasure Hunt
Each time you dig a block, there is a chance to obtain items you would not normally get from digging. See the table below for possible drop information.

There might be more than one drop per one dug block. Occasionally, Treasure Hunt will bug.

Chance Drops and Experience Table
Note: If you are bewildered on why you are getting things not on the list (ie. coal from dirt, cobble from sand etc.), please note that it is your server owner/admin modifying the plugin and it's not original McMMO.

Leveling Table (Theoretical Time)

 * The time is calculated assuming you are using a iron or diamond shovel and assumes constant digging.
 * The number of blocks you need to dig accounts for bonus exp gained from it.

Trivia

 * After skill level 350, the rate of diamond is 1 in 750 per source code. But very often you will get 1-3 diamonds within the lifespan of a normal diamond shovel.
 * Giga Drill Breaker is a reference to the anime: "Tengen Toppa Gurren Lagann".
 * While using McMMO and the Archers plugin at once, shooting the Thrice arrow at the ground is an extremely fast way to level up excavation, unless the owner/admin has set a shovel as the only way to get XP from breaking blocks in this category.
 * Because of the low probability of getting Treasure when breaking a single block, the experience you get per block does not change much from level 1 to level 1000. You get 40XP at level one and between 50XP and 53.5XP on average at level 1000 for most block types. The odd one out is clay which gives 73.3XP on average at level 1000 because of the high drop rate of string and cobwebs.
 * Digging up a cake is more rewarding than digging up a diamond, but diamonds are generally higher in demand.
 * When using a shovel with Efficiency Level 4, you can run and dig. This is a great training method if you have a diamond shovel, and even better with unbreaking so you can dig even longer.
