Universal Head Powers is a Minecraft datapack that gives new purpose to mob heads.
When you place any supported mob head in your off-hand (left hand), you will receive special potion effects that remain active until the head is removed. Each type of head gives different, useful effects, making mob heads more valuable and fun to use.
⚙️ How to install the datapack:
Launch Minecraft
Go to Singleplayer
Select a world (but don’t enter it)
Click Edit
Click Open World Folder
Open the datapacks folder
Move the UniversalHeadPowers.zip file into the datapacks folder
Enter the world
Type /reload in the chat to activate the datapack
✅ That’s it! The datapack should now work automatically.
💡Supported heads and effects: (See screenshots for a visual reference — each head gives different effects when held in the off-hand!)
🎨 I'm also working on a custom resource pack that gives each head a new texture. I’ll post the link to it on my YouTube channel, so subscribe to stay updated!
