# Masteries

Pet species Mastery: account-wide progress per species.

File: `plugins/ClickEmCore/modules/masteries.yml` (menu layout only). Module id: `masteries`. Commands: `/mastery`, `/masteries`.

Each pet **species** has a Mastery track. It belongs to the account, not to a single pet, so selling or fusing away every copy never resets it. Mastery XP comes passively from owning and using the species.

The curve and rewards are **not** in `masteries.yml`. They are in `pets.yml` under `mastery:` (the default for every species), or in a pet's own file if you override it for one species:

```yaml
mastery:
  leveling:
    base-xp: 100
    growth: 1.15
    max-level: 50
  rewards:
    per-level-currency-mult: 0.25
    titles:
      10: "clickem.masteries.title.novice"
      25: "clickem.masteries.title.expert"
      50: "clickem.masteries.title.grandmaster"
```

| `rewards.per-level-currency-mult`         | +% Coins per Mastery level, applied to every pet of the mastered species, now or later. |

VIP ranks add `mastery-xp-bonus-percent`.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://lethium.gitbook.io/lethium-docs/gameplay/masteries.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
