Efficient management of Mana and Gold is critical. Always prioritize digging towards gold veins and ensuring your Imps have a clear path to your Treasury. Build multiple Treasuries if necessary to store large amounts of gold. Mana regenerates slowly from your Dungeon Heart and faster from claimed territory. Researching 'Mana Vault' in the Library can significantly boost your Mana regeneration. Don't overspend on spells early on; save Mana for critical moments. Consider building a 'Scavenger Room' (if available) to convert dead bodies into gold or Mana. A strong economy allows for rapid expansion, powerful spells, and a well-paid army.
