Sunken Key:

This artifact has eight empty slots, each time a mech-rp is successful, it may be placed inside of one of these slots instead of granting the rewards it would typically. This artifact does not have to be equipped to place any mech-rps inside. Once all slots are filled, this artifact upgrades. This artifact cannot be upgraded via any other method. Slots: 1. 2. 3. 4. 5. 6. 7. 8. For each mech-rp in one of the above slots, the wielder of the Sunken Key gains a +1 bonus on any mech-rp made to start artifact recovery quests, increase artifact recovery quest progress per session, or create progress slots that may only be used for artifact recovery. Each age, any mech-rps stored above are automatically lost.
