Vanilla SkyBlock

🌌 SkyBlock Horizon (Server-Side Core)

A complete, premium, and feature-rich SkyBlock system designed specifically for NeoForge 1.21.1.

Unlike other mods, SkyBlock Horizon runs 100% on the server side. Players can connect to your server using a completely vanilla Minecraft client—no downloads or installs needed on their end!

✨ Key Features

🌌 Complete Void Generation (With Stronghold Support)

• Generates a completely empty void world (no land, no water, no grass, no ruined portals, no dungeons).
• Strongholds are preserved! Players can still find and use the End Portal to defeat the Ender Dragon and access the End.
• Includes a balanced Starter Chest containing only: 1x Oak Sapling, 1x Wheat Seeds, 5x Bread, 1x Water Bucket, and 1x Lava Bucket.

🏪 Double-Chest GUI Shop (/shop)

• A full, beautiful server-side Chest GUI. No ugly text links!
• Offers customized trade menus for buying and selling items in amounts of 1x, 64x, or Sell All.
• Features categories like Blocks, Farming, Ores, Food, Mob Drops, and Decorations.

🧬 Diverse Mob Spawner Tiers (T1–T3)

• Buy custom spawners for 18 different mobs divided into three tier categories: Common, Advanced, and Elite.
• Tier 1: Standard spawners with default spawn rates.
• Tier 2: Faster delay, increased spawn count.
• Tier 3: Ultra-fast delay, maximum spawn counts for ultimate grinding.
• Properties are safely injected server-side via custom NBT data.

🛒 Player-to-Player Market (/market)

• A 6-row pagination GUI allowing players to trade with each other.
• List items using /market sell <price>.
• Browse, buy, or cancel listings interactively.

📈 Balanced Base & Ore Upgrades (/skyblock upgrade)

• Expand your island’s boundary limit or upgrade the ore generator block chances.
• Upgrades require logical progression items (e.g., wood stacks, stones, blocks) instead of unrealistic iron rates.

🏆 100+ Custom SkyBlock Advancements

• Fully custom, progression-oriented advancement tree (106 advancements) tailored for SkyBlock.
• Features milestones for block breaks, mob kills, trading milestones, wealth accumulations, and base levels.
• Syncs automatically with vanilla clients.

🛡️ Other Features

• Live Scoreboard: Keep track of your coin balance right on the sidebar.
• Day Transitions: Server-wide alerts when a new day begins (e.g. ✦ Day 5 has begun! ✦).
• Visual Boundaries: Server-side particles highlight your island border when you get close to its edge.
