What is the Duel Arena?
The Duel Arena is an attraction that can be built from Ancient Ruins (located in the area next to the Innovation Workshop).
How do I unlock this territory?
To unlock this territory, you need to collect 80 archaeologist's tools. You have a chance to obtain them while collecting profit from Bungalows, but only during the “A great place” adventure.
This adventure becomes available once you reach level 9 and unlock the adjacent territories.
What is special about the Duel Arena?
The Duel Arena has 30 stages and can be upgraded using a special resource called "duelons." This resource can only be obtained as a reward for participating in Union duels. The higher your team's ranking in the duel, the more duelons you'll receive as a reward, and the faster you'll be able to upgrade the Duel Arena.
