Campaign version[]
Because the original four campaigns have not been rebalanced since the release of the game, Cupellation has different stats in those campaigns:
- It only affects gold mining rates, not stone mining (there is a separate technology for stone called Applied Masonry)
- It costs 600 gold
- The Mongol improved version costs +600 stone and increases gather rate by an additional 5% only (for a total of +20%).
