Extraction
Statistics

Extraction is a skill themed around extracting resources from lava.

Information

To train Extraction, the player will need an extraction device.

First, the player must fill the extraction device 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, the player must use either a stone bowl or diamond bowl on the filled device to extract an item from it.

How to train Extraction.

Once the player has used the bowl on the device, a block of obsidian will appear under the device. The obsidian will have to be removed to use the device again.

Upon using a bowl on the device successfully (meaning the lava is consumed), the player has a chance to acquire an item. The item will appear directly into the player's inventory (unless they have no room). In addition, there is also the chance that the player will receive nothing. The items that the player can obtain change as the player's extraction level increases - more items are available at higher levels. The chance the player will receive an item, instead of nothing, also changes with level up.

Items obtainable

The following table lists all the items available from the extraction device, as well as the extraction levels needed to obtain them.

Chance to obtain specific items

Provided the player is a specific level of extraction, all items ontainable at that level have an equal chance of being selected. As the player's level increases, and the amount of items they can obtain increases, the chance to obtain a specific item naturally goes down.

Item	Level Requirement	Quantity
Coal	Lv1	1-4
Flint	Lv1	1-4
Holly Arrow	Lv5	3-9
Blaze Powder	Lv10	1-4
Limonite Ingot	Lv15	1-3
Bone	Lv20	3-10
Silver Coin	Lv25	1-2
Emerald	Lv30	1
Experience Bottle	Lv35	1-5
Rosite Ingot	Lv40	1
Blaze Rod	Lv45	1-4
Limonite Bullet	Lv50	1-32
Ink Sac	Lv55	1-10
Fragmented Anima Stone	Lv60	1-4
Magma Cream	Lv65	2-6
Grenade	Lv70	1-8
Diamond	Lv75	1-2
Gem Bag	Lv80	1-2
Shiny Box	Lv85	1-2
Gold Coin	Lv90	1
Magic Repair Dust	Lv95	1
Occult Shovel	Lv95	1

.*Occult Shovel has 1/10 the weight that the other items do.

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

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 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

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
3	6xp	13
4	7xp	14
5	8xp	15
6	9xp	16
7	10xp	17
8	11xp	18
9	6xp	19
10	6xp	20

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