About this project

What does OneBlock: Apex add?

OneBlock: Apex

OneBlock: Apex takes the classic skyblock concept and evolves it into a fully data-driven, highly customizable incremental progression system. Break your block, progress through distinct stages, earn Island Points, and unlock permanent prestige mechanics to build the ultimate floating paradise!


Key Features

  • Data-Driven Stage Progression: Journey through fully customizable stages. Track your current block count and milestones directly on screen with a custom hex-colored HUD overlay.
  • The OB Manager: A built-in GUI to monitor stage progress, claim queued milestone rewards, and configure island upgrades.
  • Upgradable OneBlock & Discovery: Every block or event that spawns is cataloged into your learned results. Spend Island Points earned from completing stages to toggle specific blocks into your spawn pool and scale their spawn weights!
  • Prestige System: Reach the end of the final stage to prestige your island—resetting stage progress in exchange for permanent perks, boosted point multipliers, and unique endgame drops.
  • Modular Outcome Engine: Fully customizable via JSON data packs. Easily configure blocks, NBT, mob spawns, command execution, and custom costs.
  • JEI Integration: View stage details, milestone rewards, and drop chance percentages directly inside Just Enough Items.
  • Vanilla Stealth Mode: Don't want clutter on your screen? Toggle off HUD overlays, glowing outlines, and toasts anytime in the client settings menu for a clean, traditional Minecraft feel.

Modpacks & Customization

Designed from the ground up for modpack creators! Every stage, result, reward, and cost can be tweaked or expanded using standard data packs. Feel free to include OneBlock: Apex in any CurseForge modpack!
