Idle Minertia combines passive mining with strategic gear merging and wave-based combat in a prestige loop that resets progress while building permanent bonuses. Each run grows smoother as you dig deeper, collect materials, and upgrade equipment to push further in combat challenges. It's ideal for players who want incremental progression that rewards both idle downtime and active engagement with build decisions.
