Welcome to Altar Mod for NeoForge 1.21.8. This modification introduces a unique Altar block alongside custom gear, entities, and new challenges for your survival world.
⚠️ ATTENTION: The economic balance of the Altar is currently EXPERIMENTAL. Feedback and balance suggestions are highly appreciated.
What Does the Altar Do?
The Altar block allows you to clone items using a sacrifice system:
- SACRIFICE: Place any item or block inside to gain points.
- DUPLICATE: Spend your points to duplicate entire stacks of items instantly.
- TIME LIMIT: Altar points fade away if you do not use them for 40 minutes of real-world gameplay. Keep sacrificing to reset the timer.
Content Beyond the Altar
Also, the modification includes additional blocks, bosses, and high-tier equipment.
Mod Compatibility
- Vanilla Items: Default to a standard point value.
- Modded Gear: Unknown items from other modifications default to high cost to prevent easy cloning of endgame gear.
