Piggy Bank allows you to buy energy and coins at a bargain price 💰
There are two Piggy Banks: one appears on the main map and accumulates coins , and the other collects magic power in the expedition. The Piggy Bank gradually fills up as you complete levels and clear territory in the expedition. Note that winning levels of varying difficulty will bring different amounts of coins into the Piggy Bank.

Once you've saved up enough coins/magic power in the piggy bank, you can buy it all at once, or you can keep saving to buy more coins/magic power for the same price.

The maximum amount of coins/magic power that can go into your piggy bank is shown in the special offer window.
