Food

Food is a renewable resource. One food is spent every time a dungeon is entered and automatically renews by 1 every 15 minutes. The maximum amount of food is 5 and is earned while the game is closed as well.

If you enter a dungeon with no food remaining you will get a prompt to buy food to enter. The cost is 3 Gems which may be more advantageous than Reviving depending on the circumstances.
