Mining

Mining is a skill used to gather ore, , , 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 god upgrade, 3% with the , 2% with , 0.2 seconds by reaching the 50% Mastery pool checkpoint, and then by another 0.2 seconds while the + 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 with active charges. Raising Mining to Level 99 will unlock the for purchase from the Shop. Equipping the Mining Skillcape will give 1 bonus for every Mining action. The , 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 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 , the maximum HP is calculated as follows:

$\displaystyle{ \text{Rock HP}=5 + \text{Mastery Level} + \text{Bonus} }$

Where $\displaystyle{ \text{Bonus} }$ starts at 0, increasing by:

• +10 if the 95% pool checkpoint has been reached
• +20 when both the and synergy and Perfect Swing Potion is active
• The below amounts when the relevant bonuses are active:

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 $\displaystyle{ \frac{\text{Rock HP}}{1 - \text{Preserve Chance}} }$. For example, a rock with a max HP of 12 while the is being used will have an effective max HP of $\displaystyle{ \frac{12}{1 - 0.4} = 20 }$.

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 $\displaystyle{ \left \lceil 1 - \frac{\text{Action Interval (seconds)}}{10} \right \rceil }$.

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

Below lists the rock HP at various 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 . The chance of discovering a gem vein per mining action is 0.533%, which may be increased by 5% if the 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 , a 10% chance of being , and a 5% chance of being . 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.

## Ores

Higher tiers of ore are unlocked as the player's Mining level increases. The quantity received from any ore rock is doubled when are in use, and normal gems are guaranteed to drop from any ore when 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 , or can be guaranteed through the use of . If the is equipped, then this chance is increased by 10% (For example, a 20% chance becomes $\displaystyle{ 20\% \times 1.1 = 22\% }$). The chance to receive a gem is capped at 100%, so any bonuses above this limit have no effect.

While mining , there is a chance that a 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 .

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

The possible gem drops are shown below.

## Summoning Boosts

This table shows all the Familiars and Synergies that provide a bonus to Mining.

## 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 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.
