A constantly shifting form that appears to speed up and slow down unpredictably, as if time itself is being compressed and stretched around it. It leaves temporal trails like old film footage, showing glimpses of previous rounds and future possibilities. The Epoch glows with a chronometer light that pulses in rhythm with the arena's heartbeat, and it feels progressively heavier to bearers who have survived longer in the series.

The Grinding Epoch serves as a measuring stick of endurance - its weight on a player's soul indicates how close they are to the crucible's true test. Those who carry the Epoch's attention are marked as survivors of significant temporal pressure, their competitive worth measured not just by skill but by how much time they have withstood.
