Mastery
This page is up to date (v1.1.2). |
Mastery is a secondary system of levels tied to individual items within a skill. Each item in a non-combat skill (with the exception of Alt. Magic spells) has a level associated with it.
The bonuses unlocked by leveling Mastery depend on the specific skill the Mastery is associated with. To see a full list of bonuses for a given skill, check the in-game Mastery section of the completion log, or visit the wiki page for that skill.
Earning Mastery XP
Each time a player completes an action with an associated Mastery Level, they will receive Mastery XP for that item. The XP per action calculation is:
[math]\displaystyle{ \Biggl \lfloor \biggl[ \Bigl( \text{Unlocked Milestones} \times \frac{\text{Player Total Mastery for Skill}}{\text{Total Mastery for Skill}} \Bigr) + \Bigl( \text{Item Mastery Level} \times \frac{\text{Total Items in Skill}}{10} \Bigr) \biggr] \times \text{Action Time} \times 0.5 \times \left ( 1 + \text{Bonus} \right ) \Biggr \rfloor }[/math]
Where:
- Unlocked Milestones is the number of milestones the player has unlocked for the relevant skill. These can be seen in game with a level number highlighted in green when viewing milestones from the skilling minibar or skills section of the completion log. This number includes "Skill Mastery" if the player is skill level 99
- Player Total Mastery for Skill and Total Mastery for Skill are both numbers shown on each skill tile within the mastery section of the completion log
- Item Mastery Level is the mastery level of the item/action currently being crafted/performed
- Total Items in Skill is the number of items/actions within the relevant skill, and can also be expressed as [math]\displaystyle{ \tfrac{\text{Total Mastery for Skill}}{99} }[/math]
- Action Time varies depending on the skill:
- For gathering skills (
Woodcutting,
Mining,
Agility,
Thieving,
Fishing and
Astrology), this is the number of seconds taken to complete the action. As a result for these skills the Mastery XP gained per second remains the same even when the action time is decreased, however it is still worth reducing the action time to increase the amount of resources gained over time
- For artisan skills (which consume resources to produce items), the action time is a fixed value regardless of the actual time it takes the player to complete an action. Therefore for these skills, reducing the action time increases the Mastery XP gained per second:
- For gathering skills (
Skill | Seconds per Action |
---|---|
60% of the log's base burn interval | |
85% of the recipe's base cooking interval | |
1.7 | |
1.3 | |
1.65 | |
1.7 | |
1.7 | |
4.85 |
- Bonus is the percentage increase to experience gained. All available bonuses are detailed within the Bonuses section below
In other words, there are two main factors that are added together to determine the XP per action:
- The first is based on how many total Mastery levels the player has in the skill. Each item in a skill adds up to +1 to this factor depending on its current Mastery level.
- The second is based on the Mastery level of the specific item gaining XP multiplied by one tenth of the total number of items in the skill.
After both of these factors are added together, they are multiplied by half of the time per action as measured in seconds.
There are three important takeaways from this:
- Mastery XP per action increases substantially as Mastery level in an item increases.
- Mastery XP is gained much more quickly for skills with a lot of items (such as
Smithing) than it is for skills with only a few (such as
Woodcutting).
- Decreasing the action time is always beneficial: For artisan skills doing so can significantly increase the rate of Mastery XP gained, while for gathering skills this increases the rate of resources gained.
Bonuses
Aside from increasing the factors mentioned in the formula above, there are several ways to increase the Mastery XP gained:

Several Agility Obstacles provide bonuses to Mastery XP for one or more skills. However, others will reduce the amount of Mastery XP earned, so players focused on levelling Mastery should make sure their Agility course isn't slowing them down. | |
Astrology can give you a buff of up to 8% Mastery XP for most skills.
|
The Mastery Pool
Whenever the player gains Mastery XP, 25% of the amount received is also added to the Mastery Pool for that skill. After Skill level 99, the "Skill Mastery" perk increases this to 50% of the item's Mastery XP. The maximum Mastery Pool XP for a given skill is equal to 500,000 multiplied by the total number of items in that skill.
Mastery XP Pool has two uses:
First, it can be spent to level up any item mastery for a skill. Mastery Pool XP spent this way is converted to item mastery XP at a 1:1 rate.
Second, Checkpoints are reached when the Mastery Pool reaches 10%, 25%, 50%, and 95% filled. These bonuses vary by skill, but are often quite powerful. Checkpoints only remain active as long as the Mastery Pool has enough XP in it to meet the requirement - If enough Mastery Pool XP is spent on levelling items to dip below the threshold for a given checkpoint, the bonus will be lost until enough XP is gained to reach it again.
Mastery tokens can be claimed from either the bank or the spend mastery XP interface, doing so fills the Mastery Pool for the relevant skill by 0.1% of the maximum pool XP.
The cap of the mastery pool can be increased with Cape of Completion or
Harold, which increase the pool cap by 25% and 50% respectively. Increasing the pool cap makes it easier to maintain the 95% checkpoint bonus without risking the mastery pool completely filling while training a skill.
Mastery Level XP
Mastery Experience follows the same XP progression as skills do.
The experience difference between level [math]\displaystyle{ L-1 }[/math] and level [math]\displaystyle{ L }[/math] is approximately [math]\displaystyle{ \left\lfloor \frac{1}{4} \left( L-1+300\times 2^{\frac{L-1}{7}} \right) \right\rfloor }[/math]. The table below shows this experience difference for each level and also the cumulative experience from level 1 to level [math]\displaystyle{ L }[/math]. Note that experience levels are nonlinear and so the amount of experience between 1 and 92 is the same as the amount of experience between 92 and 99. Experience also doubles about every 7 levels. For example, the experience between 7 and 8 is 138 and the experience between 14 and 15 is 274, which is roughly double.
The base game has a maximum skill and Mastery level of 99, with the Throne of the Herald Expansion the skill level maximum is increased to 120.
