Extraction Device


An extraction device is used to train Extraction. First, the player must fill the extraction device with lava by placing lava on top of it. Then use either a stone bowl or diamond bowl on the extraction device. An example of what this should look like can be seen in the picture (right).

How to train Extraction.

Once the device is used once, a block of obsidian will appear in an air block under the device. If there is no block of air under the device, the lava in the device will not be consumed and the player will not received any items.

The obsidian that forms under the device will have to be removed to use the device again. Upon using the device, the player has a chance to actually find an item, otherwise finding nothing. As the player levels up in extraction, more items become available. These items are:

Chance to obtain items at all[]

The chance for the player to obtain items at all is determined by the player's Extraction level. To determine if the player should receive an item, the game selects a random number between 0 and 99 (including 0 and 99). Then the game uses the following formula: ((102 - extraction level) / 6)^1.34. The number generated by this formula is compared against the random number of 0 to 99 found earlier. If the random number is greater than or equal to the number produced by the formula, than the player will receive an item. If it is less than the formula number, than the player receives nothing.


Experience is granted to the player's skill whenever the player finds an item in the lava. Experience may also be granted if the player finds nothing at all. All items (or nothingness) give the same experience when giving experience to the player - this is scaled up as the player levels up.

Experience is calculated with the forumula 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

One of the above values, based on level, is plugged into the denominator of XP until next level / special value to calculate the amount of experience the player will obtain based on the player's level. This chart is a Work in Progress

Levels 1-10 Levels 11-20
Level Experience obtained Level Experience obtained
1 11xp 11 7xp
2 12xp 12 7xp
3 6xp 13 7xp
4 7xp 14 8xp
5 8xp 15 9xp

7 10xp 17 6xp
8 11xp 18 7xp
9 6xp 19 7xp
10 6xp 20 8xp

The following graph represents the xp required to level up extraction.
