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 Master of Nature god upgrade, 3% with the Elite Pillar of Expertise, 2% with Harold, 0.2 seconds by reaching the 50% Mastery pool checkpoint, and then by another 0.2 seconds while the Mole + Eagle Synergy is active. The percentage reductions are applied before the flat reductions, resulting in the lowest possible action time of 0.5 seconds when all reductions are active.

Ore amounts can be doubled by wearing Mining Gloves with active charges. Raising Mining to Mining Level 99 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 Mining 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 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 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:

In addition, the following can be used to provide a chance to deal no damage to rock HP while Mining:

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 Mastery levels with and without the maximum possible bonus:

Mastery Level Max Rock HP
Without Bonus With Bonus
1 6 86
2 7 87
3 8 88
4 9 89
5 10 90
10 15 95
20 25 105
50 55 135
75 80 160
99 104 184

Gem Veins

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

Ores

Higher tiers of ore 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 on ores has a 1% chance of discovering a random normal gem. This chance can be increased by any bonuses to the chance to receive gems from Mining such as that from Terra, or can be guaranteed through the use of Gem Gloves. If the Clue Chasers Insignia is equipped, then this chance 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 Mole and Octopus synergy may also be used for a 15% 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.

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 Meteorite, but only when one of the aforementioned bonuses is active, as the base chance is 0%.

Random superior gem drops cannot be doubled, nor does the Mole and Octopus synergy 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.

Perfect Swing Potion
Potion Tier Charges Effect
Perfect Swing Potion I I 30 +10% chance to do zero damage to Ores and Rune Essence
Perfect Swing Potion II II 50 +20% chance to do zero damage to Ores and Rune Essence
Perfect Swing Potion III III 80 +40% chance to do zero damage to Ores and Rune Essence
Perfect Swing Potion IV IV 100 +80% chance to do zero damage to Ores and Rune Essence

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

Gem Detector Potion
Potion Tier Charges Effect
Gem Detector Potion I Throne of the Herald Expansion I 10 +2% chance to receive a Quality Superior Gem while Mining Gem Veins or Meteorite Ore

Gem Detector Potion III Throne of the Herald Expansion III 30 +7% chance to receive a Quality Superior Gem while Mining Gem Veins or Meteorite Ore
Gem Detector Potion IV Throne of the Herald Expansion IV 40 +10% chance to receive a Quality Superior Gem while Mining Gem Veins or Meteorite Ore

Summoning Boosts

Skill Boosts

This table lists most sources of Mining-specific modifier boosts. For a list of boosts that apply to all skills, see the Skill Boosts page. This list does not contain boosts provided from Mastery rewards.

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.
