About this Mod
Vanilla Spawners Expanded
Enhance your spawners with Vanilla Spawners Expanded!
Looking to customize and optimize your spawners in Minecraft? Discover Vanilla Spawners Expanded, a Fabric mod that offers advanced configuration options for your spawners.

Features:

Spawner Calibration: Use the Spawner Calibrator on a vanilla spawner to prepare it for customization. This step is essential to unlock the full potential of your spawners. A calibrated spawner can be mined and collected even without silk touch.
Soul Capture: Capture the souls of mobs using the Cursed Bottle. Once captured, these souls can be placed into calibrated spawners to define the creatures they generate.
Available Upgrades:
-Speed Upgrade: Reduces the time between spawn cycles for faster production.
-Range Upgrade: Increases the operational range of your spawners.
-Crowd Upgrade: Allows spawners to function even when multiple mobs are already present.
-Redstone Upgrade: Control your spawners with redstone.
Configurable: Adjust the mod's settings with a detailed configuration file to tailor the experience to your preferences.
Fabric Compatibility: Designed exclusively for Fabric, this mod integrates well with other popular mods and supports mobs added by them, allowing you to customize your spawners with a wide variety of creatures.
Jade Implementation: The Calibrated Spawner block is recognized by jade and its information will be displayed in real time.
