Mining

Mining is a skill used to gather ore, Rune Essence, Pure Essence, and gems for use in many other skills.

Mechanics

Each Mining action takes 3 seconds. This time can be reduced by 5-50% by purchasing pickaxe upgrades, 15% by purchasing the

+ Eagle Synergy is active, 0.1s by wearing Dirty Mining Boots, and then by another 0.1s by being on the Terran Dungeon Ruins hex (0.2s when also owning Carthulu). Percentage reductions are applied prior to flat reductions, making it possible to reach the global minimum action time of 0.25s when sufficient reductions are active. Ore amounts can be doubled by wearing Mining Gloves with active charges. Raising Mining to

will unlock the Mining Skillcape for purchase from the Shop. Equipping the Mining Skillcape will give 1 bonus Coal Ore for every Mining action. The Superior Mining Skillcape, which becomes available once

Level 120

has been reached, increases the bonus Coal Ore quantity to 2 while also providing +5% chance to find gem veins while mining.

Rock HP

Rock HP determines how many ores can be extracted from a rock before it has to respawn. Ore and essence rocks other than

Error creating thumbnail: File missing

Meteorite

passively regenerate HP at a rate of 1 every 10 seconds, stopping when a rock reaches its maximum HP. Regeneration does not occur while a rock is respawning after being fully depleted. For ore and essence rocks besides

Error creating thumbnail: File missing

Meteorite

, the maximum HP is calculated as follows:

[math]\displaystyle{ \text{Rock HP}=5 + \text{Mastery Level} + \text{Bonus} }[/math]

Where [math]\displaystyle{ \text{Bonus} }[/math] starts at 0, increasing by:

• +10 if the 95%

• +20 when both the

• The below amounts when the relevant bonuses are active:

Classy Rock	Pet		+10 Mining Node HP
Error creating thumbnail: File missing Cool Rock	Pet		+5 Mining Node HP

In addition, the following can be used to provide a chance to deal no damage to rock HP while Mining. Note that these bonuses work for ores or essence only, not gem veins.

Source	Type	DLC	Preserve Chance

Using these bonuses effectively increases a rock's HP to [math]\displaystyle{ \frac{\text{Rock HP}}{1 - \text{Preserve Chance}} }[/math]. For example, a rock with a max HP of 12 while the Perfect Swing Potion III is being used will have an effective max HP of [math]\displaystyle{ \frac{12}{1 - 0.4} = 20 }[/math].

Due to passive rock HP regeneration, it is possible (given a sufficiently high maximum rock HP) to ensure a rock always has HP and never has to respawn, no matter how long it has been mined for. To achieve this, the player's chance to deal zero damage to ores must be at least [math]\displaystyle{ \left \lceil 1 - \frac{\text{Action Interval (seconds)}}{10} \right \rceil }[/math].

Therefore, the chance required in order to avoid respawns at the an interval of 0.85 seconds is [math]\displaystyle{ \left \lceil 1 - \frac{0.85}{10} \right \rceil = \left \lceil 0.915 \right \rceil = 0.92 = 92\% }[/math] or higher. Currently the maximum possible chance is 91% when the highest tier of Perfect Swing Potion and all other available bonuses are utilized.

Below lists the rock HP at various

Gem Veins

Gem veins do not regenerate naturally, but rather may be discovered at random when mining any ore after

Error creating thumbnail: File missing

Dragonite

. The chance of discovering a gem vein per mining action is 0.533%, which may be increased by 5% if the Superior Mining Skillcape is equipped, resulting in an overall chance of 0.56%.

The type and size of gem vein discovered is randomly determined. The discovered vein has an 85% chance of being Onyx, a 10% chance of being Oricha, and a 5% chance of being Cerulean. The size of the vein may be either small, medium, or large:

• Small veins are discovered with a 62.5% chance, having an HP between 5 and 15
• Medium veins are discovered with a 25% chance, having an HP between 10 and 25
• Large veins are discovered with a 12.5% chance, having an HP between 20 and 60

Meteorites

Meteorites can be discovered at random while studying any constellation in

. When discovered, the HP of the meteorite rock will be increased by a random amount between 5 and 24 HP.

Pickaxes

Pickaxes are permanent upgrades purchased from the Shop that decrease the amount of time it takes to mine ore by their bonus speed percentage. The later pickaxes also provide a number of other bonuses, as listed in the table below. The bonuses provided by these upgrades are permanently active once purchased, they do not need to be equipped or otherwise enabled.

Rocks

Higher tiers of rocks are unlocked as the player's Mining level increases. The quantity received from any ore rock is doubled when Mining Gloves are in use, and normal gems are guaranteed to drop from any ore when Gem Gloves are used, however neither of these gloves have any effect when used while mining essence or gem veins.

Gems

Normal Gems

Each Mining action has a 1% chance of discovering a random normal gem. The chance to receive gems when mining ores can be increased by bonuses such as that from

Error creating thumbnail: File missing

Terra

, or can be guaranteed through the use of Gem Gloves. If the Clue Chasers Insignia is equipped, the chance to find gems is increased by 10% (For example, a 20% chance becomes [math]\displaystyle{ 20\% \times 1.1 = 22\% }[/math]). The chance to receive a gem is capped at 100%, so any bonuses above this limit have no effect.

While mining Pure Essence, there is a chance that a Runestone will be dropped instead of a normal gem. The chance of Runestone drops is not subject to the usual normal gem drop chance bonuses, and so the base chance of 1% may only be increased to 1.1% while wearing the Clue Chasers Insignia.

Any gems dropped (including Runestones) may be doubled if any global or Mining specific item doubling bonuses apply. The

Error creating thumbnail: File missing

Mole

and

Error creating thumbnail: File missing

Octopus

synergy and/or Gem Finder Scroll may also be used for a chance to receive an additional normal gem of any type whenever a normal gem is dropped while Mining - this additional gem also has a chance to be doubled. If the synergy is active while mining Pure Essence, then a Runestone will be obtained in place of a random gem.

Superior Gems

Superior gems can drop from any gem vein (in addition to the gem provided by mining the vein) with a chance of 10% per action. This chance can be increased by any things providing a bonus to the chance to receive a quality superior gem. Superior gems may also drop while mining

Error creating thumbnail: File missing

Meteorite

, but only when a bonus to the chance to receive a superior gem is active, as the base chance is 0%. Random superior gem drops cannot be doubled, nor does the

synergy or Gem Finder Scroll apply.

The possible gem drops are shown below.

Potion

The Perfect Swing Potion provides a chance to mine from a rock without lowering the rock's HP. This potion has no effect while mining from a gem vein.

Perfect Swing Potion
Potion	Tier	Charges	Effect
	I	30	+10% chance to deal no damage to Essence Nodes in Mining and +10% chance to deal no damage to Ore Nodes in Mining

	IV	100	+80% chance to deal no damage to Essence Nodes in Mining and +80% chance to deal no damage to Ore Nodes in Mining

The Gem Detector Potion provides a chance to receive a quality superior gem while mining either a gem vein or Meteorite Ore.

Trivia

Prior to the release of V1.0, the source code file for the Mining skill was called rockHitting.js, which is in contrast to other skills' source files which are named eponymously (i.e., woodcutting.js for Woodcutting). This used to be case for Mining as well[1], however it turned out that some browsers or extensions block a script called mining.js, likely in an attempt to prevent unwanted crypto mining, so the file was eventually renamed.

Upon release of V1.0, Mining became one of a small number of tick-based skills, at which point the source file was renamed once more to rockTicking.js.
