Usage[ | ]
Extraction devices are used to train Extraction. They need an empty space underneath to function.
First, the extraction device must be filled with lava by placing lava on top of it. An example of what this should look like can be seen in the picture (right). Once the device is filled, either a stone bowl or diamond bowl must be used on the filled device to extract an item from it.
How to train Extraction.
Once the bowl is used on the device, a block of obsidian will appear under the device. This must be removed to use the device again without moving it.
With each usage of the device, there is a chance to acquire an item. This goes directly into the inventory unless it has no room. There is also a chance to receive nothing. As the player's extraction level increases, more types of items are unlocked, and the chance to receive nothing decreases.
Rewards[ | ]
Chance to obtain experience[ | ]
An initial check is run before picking rewards. This check is Random number >= ((102 - extraction level) / 6)^1.34. The random number is an integer between 0 and 99 (inclusive).
If this check fails, neither items nor experience are granted.
Chance to obtain specific items[ | ]
Once the experience check completes, a loot table is rolled to determine the reward item. As the player's Extraction level increases, the number of different items available also increase. All of these options have the same weight, and thus have the same chance of being selected, with one exception. As a result, an increase in level results in a decrease in the chance to obtain any given item.
There is still a chance to get no items, although unlike when the first check fails, getting no items here will still give experience.

Experience[ | ]
Extraction experience is granted whenever the experience check succeeds. All loot options (including the one that doesn't reward any items) give the same experience, which increases as the player levels up.
Experience is calculated with the formula XP until next level / special value, with the special value being set in the code. Below is the list of special values placed in the denominator, based on levels:
| Level | Special value |
|---|---|
| 1-2 | 5 |
| 3-8 | 10 |
| 9-16 | 20 |
| 17-25 | 35 |
| 26-40 | 60 |
| 41-60 | 90 |
| 61-75 | 150 |
| 76-98 | 300 |
| 99-100 | 500 |
The following graph represents the xp required to level up extraction.
