## Hazards

A **hazard** is an environmental threat attached to a room — a sandstorm, solar
radiation, falling rocks, toxic spores. Define it once in
`data/hazards/<id>.yaml`, then reference it from any number of rooms with
`hazard: <id>` (see `rooms.md`).

**The filename is the ID** (`solar_radiation.yaml` → reference it as `hazard: solar_radiation`); the loader derives it from the filename. Do not put an `id:` field in the file — it is ignored.

```yaml
name: scorching solar radiation

### Combat Fields

The `combat:` block mirrors a mob's combat block exactly — same stats, same bonuses,
same per-type max hits. Hazards have **no defense stats** because they are never
attacked — they only attack the player.

| Field | Description |
|---|---|
| `combat.attack_types` | List of attack types. At least one melee (`stab`/`slash`/`crush`) plus optional `ranged`/`science`. The first melee type is used as the primary attack type. |
| `combat.stats.attack` | Attack level (base accuracy) |
| `combat.stats.strength` | Strength level (melee max-hit base) |
| `combat.stats.ranged` | Ranged level (ranged accuracy base) |
| `combat.stats.science` | Science level (science accuracy base) |
| `combat.stats.speed` | Ticks between hazard rolls (default 5) |
| `combat.stats.max_melee_hit` | Maximum melee damage per hit |
| `combat.stats.max_ranged_hit` | Maximum ranged damage per hit |
| `combat.stats.max_science_hit` | Maximum science damage per hit (a set value — not level-derived) |

#### Bonuses (`combat.stats.bonuses:`)

| Field | Description |
|---|---|
| `attack_bonus` | Equipment-equivalent attack bonus (added to accuracy roll) |
