Newest update: The Undervault Update (2026-08-22)
- Three and a half months of digging in one print. The Undervault: claim your own mine, rank it up, and put Sylas the servant to work at his enchant altar. The shared mine turned dangerous — PvP with haul sacks to loot, a safe zone, and the Miners' Trade Post to sell your ore before someone takes it. Money and rank now live per-mine, and rank-up is bought at the merchant, never automatic. Plus: the plots yard to build on, carryable lamps, crates and cosmetics, and real saves — your progress survives the night. Under it all, a long engine climb: the voxel shimmer is gone and every lantern got retuned.
