1 per world · nearest usually 2,372 m from spawnThe refinement altar. Ten Mountain sites are reserved per world and the first one a player loads is the one that gets built; the other nine vanish. An idol plus a piece of gear is a 65% chance of one more quality level and a 35% chance of losing the item.
Ten sites are reserved when the world is generated, at least 400 m apart, and the first one a player loads is the one that gets built; the other nine are deleted at that moment. They go in the Mountain, away from the biome's edges. Distance from the world centre: beyond 200 m. Altitude above 0 m relative to sea level. Placed before ordinary locations, so it takes first pick of zones. Marked on the map once a player has been near it.
