A lightweight server-side Fabric mod that dynamically scales the Ender Dragon's health based on the number of players in The End — now with support for delayed initial spawns and XP bar countdowns.
No installation is needed on the client — just drop it into your server's mods folder and configure it to your liking.
- 📈 Dynamic Health Scaling: The Ender Dragon's max health increases with each eligible player in The End.
- ⏱️ Initial Spawn Delay: Optionally delay the very first dragon spawn and show a countdown on players’ XP bars.
- ⚙️ Server-Side Only: No client installation required — perfect for modded or vanilla-compatible SMPs.
- 🔧 Configurable: Customize how scaling and spawn delays work via a simple
.propertiesconfig file. - 📢 Broadcast Messages: Optional announcements when a scaled dragon appears.
- 🛠️ In-Game Reload:
/scaleddragonfight reloadcommand to reload configuration without restarting the server.
After first launch, a config file will be generated at:
/config/scaleddragonfight.properties
You can configure:
enableMod=true # Enable or disable the mod
scaleWithOnePlayer=false # Whether scaling starts with the first player
countCreativeModePlayers=false # Include creative players in scaling
baseDragonHealth=200.0 # Base health of the Ender Dragon
additionalHealthPerPlayer=100.0 # Health added per eligible player
enableBroadcast=true # Enable broadcast when dragon spawns
# Initial Spawn Delay
enableInitialSpawnDelay=true # Delay the first dragon spawn in The End
initialSpawnDelaySeconds=60 # Time (in seconds) before first dragon spawns

⚠️ Mod/Datapack Interactions: This mod modifies vanilla Ender Dragon spawning logic. It may exhibit unintended behavior or conflicts with other mods/datapacks that introduce custom dragon spawning mechanics (e.g., True Ending). While I aim to improve compatibility in the future, full support for third-party dragon overhauls is not guaranteed.
