MD22

OneBlock skyblock, built for servers: every player who joins gets their own island in the void, automatically. A random item falls out of the block every few seconds. Vanilla datapack — no mods, no client install.

Auto-smelting as you mine: iron, gold and copper ore give finished ingots straight from the block, no furnace and no fuel. Fortune and Silk Touch work exactly as in vanilla. Server-side datapack.

Auto replant for farming: break a grown crop and it sows itself again from one seed of the drop. Wheat, carrots, potatoes, beetroot and nether wart. Server-side datapack - no mod, nothing for players to install.

Set how long the day and the night last - separately. Long days with normal nights, or any mix, with two numbers. Server-side datapack: no mod, no client install, works on a world you already play.

A deeper sky without a resource pack: richer sunsets, nearly twice the stars and a blue night instead of a grey one. Server-side datapack - every player sees it, nobody installs anything.

Stand on wool and jump to rise to the next block of the same colour, sneak to drop down. Sixteen colours, sixteen independent shafts. Server-side datapack - no mod, nothing for players to install.

Died far away? Respawn, type /trigger back and return to where you died, even across dimensions. Once per death, no operator rights needed. Server-side datapack - nothing for players to install.

Villager and wandering trader prices never rise from heavy trading. Trade limits, restocks and the cure discount stay vanilla. Server-side datapack - nothing for players to install.

Big XP orbs are credited all at once instead of trickling in. Mending items still get repaired by vanilla. Server-side datapack - nothing for players to install.
