Randon One Block

An experimental AI-built modpack — no grand plan, just curiosity.

This pack exists because I wanted to see how far AI (Grok Composer 2.5 fast) could take a real Minecraft 26.1.2 NeoForge project. I do not mod by hand: I describe what I want, and the AI writes configs, KubeJS scripts, quests, and pack structure. Randon One Block is that experiment made playable.

1.1.0.0 is the endgame milestone: the quest book still opens the mod pools, the Randon Atlas is the collection finish, and The Echo is the 100,000-mine finish. 1.1.0.1 adds Light Level Overlay — press F7 to show or hide where mobs can spawn.

Why “Randon”?

Randon is not a clever brand — I simply misspelled Random when creating the GitHub repo (Randon-One-Block). CurseForge asked for a project name without “mod/modded” or loader names in the title (so Modded Random OneBlock and Random Modded One Block were both rejected). The repo typo became the official name Randon One Block instead of renaming folders and links everywhere. The gameplay is still a random one-block skyblock; the name is just an honest mistake that stuck.

What you do in-game

You start on a simple Haven skyblock island. In the middle sits one block. Break it and a new random block from anywhere in the modpack appears in its place — then break that, and roll again.

That loop was built with KubeJS, with heavy inspiration from Chaos OneBlock. Huge shout-out to that pack’s creator — the random one-block idea is theirs; this is a separate mod list, Haven islands, and our own scripts.

Early rolls stay mostly vanilla + a few starter mods. Completing certain quests unlocks whole mod namespaces into your team’s random pool (storage, Ex Deorum, Equivox, and more as the book grows).

Progression highlights:

• FTB Quests — mod chapters with full descriptions (Getting Started, Storage, Ex Deorum, Equivox, Iron Furnaces, Mystical Agriculture, Ender IO, Refined Storage, Powah, and more), plus Randon Mined, The Atlas, and The Echo.
• The Uncrafting Table — a custom mod for Minecraft 26.1.2: reverse a crafting recipe and get ingredients back. Nothing like it existed for this version, so AI helped create it for the pack.
• Equivox — feed the ingredients you recover from the Uncrafting Table into Equivox’s transmutation grid to build EMC (Energy-Matter Currency). Craft the Philosopher’s Stone (The Red Rock) to unlock Equivox blocks in your random pool. (ProjectE was renamed Equivox for copyright reasons.)
• Randon Mined — team counter above the hotbar for center blocks broken. Milestones unlock more pools (BBL Utility at 500, a choice at 1,000 and 5,000, Easy Ore Generation at 2,500).
• The Atlas — every distinct center-block roll is a page for your team. A curated endgame set is the real collection goal. Filling the active set grants the Atlas Seal. Open the quest tab The Atlas, or run /randomblock atlas.
• The Echo — at 100,000 team mines the center block becomes The Echo once (not a random roll). Online teammates get an Echo Seal. At 50,000 the book marks Echo Approaches.
• The Randon Ending — the quest tab The Echo completes when the team has both seals. Finish the Atlas first or the mine count first; either order works.
• Everything else is “mods I liked” thrown together on skyblock.

Quick start

1. Create a world with preset haven_skyblock_builder:skyblock_world
2. Run: /havensb island create oneblock_island My Island
3. Mine the center dirt on the small pyramid — it will keep re-rolling random blocks
4. Watch Randon Mined : above the hotbar — your team total for center blocks broken
5. Open the FTB Quest book in your hotbar for starter tasks

Stuck with an unbreakable roll? Use the repeatable Cant mine the block? quest to reset the center to dirt.

Versions

Expectations

• This is an experimental AI-assisted pack, not a polished expert pack — but 1.1.0.0 has a real end: Atlas Seal, Echo Seal, then The Randon Ending.
• Balance and content will keep growing as the AI-assisted workflow continues.
• Bug reports and ideas welcome on GitHub Issues.

If you want a polished one-block experience, play Chaos OneBlock too — and thank its creator for the concept that started this rabbit hole.
