OneBlock Minecraft 1.21 servers

A single block under your feet that regenerates every time you break it, with phases that get richer and richer. OneBlock servers give SkyBlock a surprising twist. The last version of the old 1.x numbering (Tricky Trials, then the 1.21.x updates): trial chambers, the Breeze, the mace and new copper blocks. A very common base, stable and rich in plugins. This month, Evolya leads with 2 votes.
