Each price is what you pay to reach that level. The menu always shows your next level and its price.

Cobblestone generator

The generator upgrade changes what a cobblestone generator can make in your island’s Overworld. Each cell is the chance for that block. Prices are what you pay to reach each level.

Island bank

  • Open /is bank to see the island bank. Put money in with /is deposit <amount> and take it out with /is withdraw <amount>.
  • There is no limit to how much the bank can hold. Island roles decide who can deposit or withdraw, so check /is permissions.
  • The bank keeps a log of deposits and withdrawals.
  • Bank money counts toward your island worth: every $1,000 adds 1.
  • The bank pays interest: 10% of the balance about once a day, as long as the island owner was online in the last day.
  • Deleting your island does not refund the bank.
