Sacred Rock Unlock Key is not worth it 🗿

After completing around 140 Requests for the Black Market, the Sacred Rock Unlock Key will be available for purchase in the Item Shop. To be more precise the Unlock Key will be available after accepting the 32nd Request from the Candy Store. Just ask one of your Black Market Friends to drop the Key for you, it is better that way. You can leave the Association by paying   [ ⓜ 150,000 ]  and re-join the Association by paying  [ ⓜ 200,000 ]  but the price will increase each time you kill another Player.
