We are correcting Artifact mining tomorrow.

Endurance made each Artifact’s mining power fall over time. It addressed the right problem: mining without a lifetime limit gave every Artifact unbounded MST output.

But it was incomplete. Daily rates kept falling, while mining still had no true endpoint.

A declining rate is not a finite lifetime.

The replacement:

The original flat-rate formula returns: element value × 0.5% × rarity modifier.
Every Artifact gets a fixed lifetime MST reserve.
No daily rate decay.
At zero Remaining MST, mining stops and the card remains as a permanent Relic.
Without new crafting, active Artifacts can only exhaust finite remaining reserves. Renewing mining output means returning to the Forge. That is the balance the economy was missing.

This is not a reset. Claimed and stored MST remain yours. Existing mining history counts toward the reserve. The seven-day storage rule is unchanged; reserve is spent only while MST accrues.

Craft. Mine. Keep.
