About this project
What does OneBlock-IsLand add?
Welcome to the ultimate One Block experience! This isn't just about breaking a single block; it's a carefully designed survival journey with built-in RPG progression and a custom economy. You start on a single block in the void, but as you mine, you will advance through different Ages and unlock unique features!
🌟 Key Features:
Progressive Ages & Infinity Mode: The block evolves as you mine. Reach the final "Infinity Age" where all blocks spawn with a balanced rarity weight.
Milestone Loot Chests: Every 500 blocks you break, a special reward chest spawns filled with useful loot!
5 Custom NPC Merchants: Say goodbye to useless junk blocks! At specific milestones (250, 750, 1250, 1750, 2250), custom immortal Villagers will spawn. Sell your extra dirt, logs, and farm goods to earn Emeralds, and use them to buy everything from water buckets to spawn eggs.
The Endgame Champion: Save your Diamonds! The final merchant doesn't care about emeralds; they trade God-tier enchanted gear, Totems, and Elytras for your hard-earned Diamonds and Netherite.
Gravity Block Safety Net: A hidden 3x3 bedrock platform spawns under the block to catch falling sand and gravel. No more losing items to the void!
Can you build a massive empire from just a single block? Download now and start your journey!
