Editing Mastery

'''Mastery''' is a depth system layered on top of every skill: each individual action carries its own personal '''mastery level from 1 to 99''', earned simply by doing that action. Mastery gives even a low-level action a reason to keep running it — every completion, no matter how basic, is progress toward a perk. On top of the per-action ladders, each skill has a shared '''Mastery Pool''' that pays out skill-wide bonuses.

== Earning Mastery ==

* Every time an action completes, it earns mastery XP toward that action's own 1–99 ladder.
* The amount earned per completion is fixed for a given action: '''slower actions and higher-level actions earn more per completion'''.
* Because the award is tied to an action's base speed, any speed boost you have (gear, [[Pets]], [[Museum]] wings, etc.) also raises your mastery gained per hour.
* Reaching mastery 99 on a single action takes roughly '''90 focused hours''' at typical speeds — it is a long-tail goal.

Almost every action in the game has a mastery ladder: gathering, crafting, [[Ecology|expeditions]], [[Skills|delves]], [[Arenas]], and [[Taming|tames]]. ([[Skills|Farming]] is plot-based rather than action-based, so it has no mastery.)

== Per-Action Perks ==

Each action's ladder pays out perks at mastery '''25, 50, 75, and 99'''. The exact perk depends on what kind of action it is:

{| class="wikitable sortable"
! Mastery !! Gathering / Crafting actions !! Expeditions / Arenas !! Tames
|-
| 25 || −5% action time || −5% action time || −5% action time
|-
| 50 || every 10th completion yields double output || +3 expedition score || +5% to the tamed creature's stats
|-
| 75 || −5% more action time || −5% more action time || −5% more action time
|-
| 99 || +25% to the primary output || +6 more score (+9 total) || +10% more stats (+15% total)
|}

The mastery-50 "double output" trigger is deterministic — it lands on exactly every tenth completion, not a random roll. The time-reduction perks stack together. On '''Expeditions''' and '''Arenas''', the mastery-50 and mastery-99 score perks now '''scale with the action's difficulty''' (about +3% of difficulty each), so the reward keeps growing on the hardest content instead of capping at the flat bonus.

== The Mastery Pool ==

Every skill has its own '''Mastery Pool''', a shared reservoir that fills as a side stream and pays skill-wide bonuses:

* '''Filling''': a quarter (25%) of every mastery XP award also flows into that skill's pool — this is extra, nothing is taken away from the action's own progress.
* '''Capacity''': the pool's cap scales with how many actions the skill has, so skills with big rosters (like Expeditions) take far longer to fill than small ones (like Delving).
* '''Checkpoints''': the pool grants a bonus while it sits at or above each threshold:

{| class="wikitable sortable"
! Pool filled !! Skill-wide bonus (while at/above this level)
|-
| 10% || +10% mastery XP earned
|-
| 25% || −2% action time
|-
| 50% || +25% mastery XP earned
|-
| 95% || −3% action time
|}

* '''Spending''': you can spend pool XP to instantly buy the XP an action needs to reach its next mastery level. This is the system's central tension — spending can drain the pool '''below''' an active checkpoint, switching that bonus off until the pool refills. Hoard the checkpoints, or cash out to push a favorite action forward.

== Skill Mastery Milestones ==

Separate from the pool, each skill tracks how much of its '''total possible mastery''' you have earned — the sum of every one of its actions' mastery levels, against a maximum of every action at 99. Crossing three thresholds grants standing, always-on bonuses to that whole skill:

{| class="wikitable"
! Milestone !! Reward
|-
| 20% of total mastery || +1% output on the skill's actions
|-
| 45% of total mastery || −2% action time on the skill's actions
|-
| 75% of total mastery || the mastery-50 "double output" now triggers every '''8th''' completion instead of every 10th
|}

Because these read the whole skill at once, they reward broadly levelling every action rather than perfecting a single one.
