Development history

Before Dailyscape Overhaul, the rock in the Ithell crystal sandstone mine could only be mined a total of 50 times daily, while the one in the Meilyr crystal sandstone mine could only be mined 25 times daily. As the rock was mined, it would visually appear more and more depleted until it had been fully mined. The daily limit would reset on login, after 00:00 game time. The daily limit could also be reset by casting Advance Time.

• patch 23 March 2026 (Update):
  • Rebalanced Red and Crystal Sandstone to have reduced hitpoints.
    • Hitpoints reduced: 1,800 → 800 (Ithell) / 1,700 → 750 (Meilyr)
    • Experience multiplier reduced: 0.82 → 0.50

• update 16 March 2026 (Update):

    • Hardness: 0 → 180
    • Hitpoints: 100 → 1,800 (Ithell) / 1,700 (Meilyr)
      • The sandstone in Meilyr, which has extra requirements, now has lower hitpoints, making it quicker and easier to mine.

• patch 18 February 2019 (Update):
  • The Resourceful aura will once again display a text message if you've gained an extra Crystal-flecked or Red sandstone when mining.

• patch 4 February 2019 (Update):
  • Mining Red/Crystal Sandstone now has maximum stamina and does not reduce your stamina, so that your mining rate will not steadily reduce while emptying it. It, therefore, does not count toward the My Sick Four Tick Trick achievement to maintain nearly maximum stamina.

• patch 16 November 2015 (Update):
  • A typo that occurred with the depletion of crystal-flecked sandstone rock has been fixed.
