# All Mechanics

> Every available mechanic, grouped by category.

Mechanics are the **what** of an effect line: the action itself. Every mechanic takes its options in a `{key=value;key=value}` block written directly after the name, with no space:

```yaml theme={null}
- potion{type=poison;duration=10s;level=1}  #onHurt @target
```

## Rules that apply to every mechanic

* **Names, aliases and attribute keys are case-insensitive.** `Damage`, `damage` and `DAMAGE` are the same.
* **Durations accept time units:** `2s`, `1.5m`, `500ms`, `40t` or plain `40` (ticks). Works in every duration attribute.
* **Colors** use legacy `&` codes: `&6Golden text`.
* Message mechanics accept a bare quoted string: `narrate "hi"` equals `narrate{message=hi}`.
* Player-only mechanics (messages, titles, item gives) silently skip non-player targets.
