# How to Configure Blood Moon Settings on Your 7 Days to Die Server (/docs/7-days-to-die/blood-moon)



import { Step, Steps } from 'fumadocs-ui/components/steps';

Every 7th in-game day, the blood moon rises and a relentless zombie horde attacks. Here's how to configure it.

Blood Moon Settings [#blood-moon-settings]

All settings are in `serverconfig.xml`:

```xml
<property name="BloodMoonFrequency" value="7" />
<property name="BloodMoonRange" value="0" />
<property name="BloodMoonWarning" value="8" />
<property name="BloodMoonEnemyCount" value="8" />
```

| Setting               | Default | Description                                                                                                       |
| --------------------- | ------- | ----------------------------------------------------------------------------------------------------------------- |
| `BloodMoonFrequency`  | `7`     | Days between blood moons. Set to `0` to disable entirely.                                                         |
| `BloodMoonRange`      | `0`     | Random variance in days. If set to `2` with frequency `7`, blood moon can occur day 5–9 instead of exactly day 7. |
| `BloodMoonWarning`    | `8`     | In-game hour the sky turns red (22:00 = 10 PM). Set to `-1` to disable warning.                                   |
| `BloodMoonEnemyCount` | `8`     | Max alive zombies **per player** during the horde.                                                                |

How the Horde Works [#how-the-horde-works]

1. Sky turns red at the warning hour (default 10 PM / 22:00)
2. At nightfall (22:00), the horde begins — zombies know exactly where every player is
3. Zombies spawn continuously, up to `BloodMoonEnemyCount` alive per player at once
4. The horde ends at dawn (04:00 / 4 AM)
5. Zombie composition depends on player **Game Stage** — higher Game Stage = tougher zombies

Zombie Count Math [#zombie-count-math]

`BloodMoonEnemyCount` is **per player**, and it interacts with `MaxSpawnedZombies`:

* 4 players × count of 8 = up to 32 simultaneous blood moon zombies
* The global `MaxSpawnedZombies` cap still applies
* If the global cap is lower than the per-player total, some players may see fewer zombies

Common Configurations [#common-configurations]

Disabled (No Blood Moons) [#disabled-no-blood-moons]

```xml
<property name="BloodMoonFrequency" value="0" />
```

Frequent Hordes (Every 3 Days) [#frequent-hordes-every-3-days]

```xml
<property name="BloodMoonFrequency" value="3" />
<property name="BloodMoonEnemyCount" value="12" />
```

Random Blood Moons (Unpredictable) [#random-blood-moons-unpredictable]

```xml
<property name="BloodMoonFrequency" value="7" />
<property name="BloodMoonRange" value="3" />
```

Blood moon occurs randomly between day 4 and day 10, then 11–17, etc.

Brutal Horde Night [#brutal-horde-night]

```xml
<property name="BloodMoonFrequency" value="7" />
<property name="BloodMoonEnemyCount" value="16" />
<property name="ZombieBMMove" value="4" />
<property name="BlockDamageAIBM" value="150" />
```

Game Stage and Zombie Composition [#game-stage-and-zombie-composition]

The zombies that spawn during blood moon scale with each player's **Game Stage**, which increases based on:

* Player level
* Days survived
* Number of party members nearby

Higher Game Stage = more feral zombies, radiated zombies, demolishers, and cops in the horde.

> 💡 **Tip:** If blood moons feel too easy, increase `BloodMoonEnemyCount` before raising `GameDifficulty` — more zombies is a bigger challenge than just tougher individual zombies.
