Description
This survival overhaul triggers a nationwide Purge from Day 10 through Day 100 where hostile spawns ramp up massively and there are no safe zones — every player is targeted in any dimension regardless of light, biome, or base. Purge days apply roughly tenfold hostile spawn pressure with reinforced mobs, and starting on Day 16 every night becomes a Blood Moon that forces thunder, strengthens enemies, adds visual effects, and applies player-affecting conditions while HUD/action-bar timers and announcements keep you informed. A dramatic Day 9 warning broadcast with sirens and voice-style alerts signals the imminent threat, and start/end announcements occur for each purge phase, so prepare defenses, arm up, or run when the countdown begins.

Blood Moon Purge
Quickstart
- Install the
.mcaddonfile — it adds both a behavior pack and resource pack. Apply both to your world before loading it. - Start a new survival world (or load an existing one). The mod activates automatically — no crafting or commands needed.
- Use your first 9 days to prepare: gather resources, build defenses, stock food and weapons.
- On Day 9, sirens and emergency broadcasts will warn you. The Purge begins at dawn on Day 10.
- Survive until Day 101 to see the Purge end.
Overview
Blood Moon Purge is a survival overhaul that transforms days 10 through 100 into a relentless gauntlet. Hostile mob pressure rises to roughly 1000% of normal, no safe zone exists anywhere — not underground, not in the Nether, not in the End — and every night from Day 16 onward becomes a Blood Moon. The mod is entirely automatic; it tracks world days and adjusts the difficulty, announces phase changes, and applies effects without any player input.
What It Adds

|---|---|---|
| Day 9 Emergency Broadcast | Day 9 (all day) | Repeated siren sounds and chat/title alerts warning the Purge is imminent |

| Blood Moon Nights | Every night from Day 16 | Forced thunderstorm, strengthened enemies, visual effects, player status conditions |
| HUD / Action-bar timers | During Purge | Ongoing countdowns and phase announcements displayed on screen |
| Purge End Broadcast | Day 101 | Global title and chat announcement; normal hostile pressure restored |
How To Use
No interaction is required. The mod runs entirely on world-day tracking. Here is what happens at each key milestone:
Day 9 — Emergency Alert
Multiple rounds of alarm sounds (raid horns, thunder, wither and evoker cries) play for all players. A red SERVER EMERGENCY ALERT title appears on screen and chat messages explain what is coming. Use this day to finish your last preparations.
Days 10 – 100 — The Purge
- A THE PURGE HAS BEGUN title broadcasts to all players at dawn on Day 10.
- Hostile mobs spawn at roughly ten times the normal rate in every dimension and every biome, regardless of light level or player shelter.
- Mobs are reinforced (tougher than their standard variants).
- The action bar displays timers and status updates throughout.
Nights from Day 16 — Blood Moon
Each night during the Purge (starting Day 16) triggers Blood Moon mode:
- The sky forces a thunderstorm with a blood-red visual tone.
- Enemies gain additional strength buffs.
- Players receive status-effect conditions.
- Visual and audio effects intensify the atmosphere.
Day 101 — Purge End
A THE PURGE HAS ENDED title and chat message broadcast to all players. Hostile spawn rates return to vanilla levels.
Abilities And Mechanics
Spawn Pressure
During the Purge, hostile mob spawning is amplified to approximately 1000% of normal. This applies in all three dimensions (Overworld, Nether, End) and ignores light levels, meaning mobs can appear even in well-lit areas.
Reinforced Mobs
Purge-active mobs are stronger than their base counterparts. Expect higher health, damage, or additional buffs depending on mob type.
Blood Moon Conditions
On Blood Moon nights the following stack on top of base Purge pressure:
- Forced thunder — weather is locked to thunderstorm regardless of natural cycle.
- Enemy buffs — hostile mobs receive further strength increases.
- Player debuffs — status effects are applied directly to players, impeding survival.
- Visual effects — the sky and environment shift to reinforce the Blood Moon atmosphere.
No Safe Zones
The mod explicitly targets every player in every dimension. Underground bunkers, Nether fortresses, and End islands all receive the same elevated spawn pressure. There is nowhere to hide.
Progression And Strategy
Days 1 – 9 (Preparation Window) This is your only true safe window. Prioritize:
- Building enclosed, well-lit shelter with multiple layers.
- Stockpiling food, arrows, potions, and armor.
- Mining for iron/diamond gear before Day 10.
- Setting up farms so you have renewable resources during the long Purge.
Days 10 – 15 (Early Purge) Full spawn pressure is active but Blood Moon nights have not yet started. Learn mob patterns and test your defenses while conditions are at their least extreme.
Days 16 – 100 (Blood Moon Purge) Every night becomes a Blood Moon. Consider:
- Spending nights inside a hardened structure and fighting only when necessary.
- Keeping potions of healing and status-cure on your hotbar to counter player debuffs.
- Cooperating with other players — the chat broadcasts encourage surviving together.
- Using ranged weapons and traps to reduce direct combat risk.
Day 101+ (Aftermath) The Purge ends automatically. Hostile spawning returns to vanilla rates, giving you the chance to rebuild, explore, and recover.
