One Block To End All One Blocks
by sworcery
Players start on a single sky block in this Fabric minigame and advance by completing quests across six phases.
What it does
Each player gets a personal island, 250 blocks from the next one, and the progression is driven by quests. Breaking the single block yields drops, and those drops, together with crafting, mining, kills and inventory progress, complete the quests. Completing them moves the player to the next phase, and each phase adds new drops to the cumulative block pools. Quest progress is tracked automatically through Minecraft's own statistics system, and boss waves appear at major phase milestones.
The mod includes a team system: a player can create a team, invite others and manage members. Teammates who build a bridge between their islands see the mod detect the connection and merge them. Players can also visit open islands of other players. A server-side configuration supports multiplayer, and when one player reaches a new phase, every other player is advanced and the achievement is broadcast server-wide.
The mod requires Fabric API. It is open source under the MIT License and is published for Fabric only, with files for 1.21.4.
Key features
Six progression phases
Each of the six phases adds new drops to a cumulative block pool, so the drops available grow as the player advances.
Quests in each phase
Four quests per phase track crafting, mining, kills and inventory progress, and they update without manual input.
Journal screen
Pressing J opens a full interface showing active quests, block and mob pools, a leaderboard, and island management.
Phase HUD overlay
A configurable overlay shows the current phase and quest progress, with adjustable position, scale and toast notifications.
Team islands
Teams can be created and managed, and two teammates merge their islands by building a bridge between them.
