Civillis

Build more, spawn less. Hostile mobs naturally avoid civilized areas.

Civillis is a Fabric mod that suppresses hostile mob spawning near player-built structures by computing a real-time civilization score based on block composition. No special items, no commands — just play, and the land responds.
