The Ancient Portal is used to travel from the Archipelago to the Campaign Map by selecting it and pressing the button. The level of the Portal determines the base number of Battle Energy available for use on the Campaign Map. Each time the Portal is upgraded , both the Portal Energy and the Arena Energy are replenished. The level of the Portal does not affect the amount of Arena Energy, as that amount depends on the player's VIP Status. The size of the Portal is 7x7 squares, regardless of its level, which makes it the largest movable building in the game.
Users of VIP Level 11 and above can switch between the normal aspect of the Portal and a golden variant . The Golden Ancient Portal serves no purpose other than an aesthetic enhancement. This option can be used even when the VIP Status is not active.
- Update 3.2 increased the VIP level at which the golden form of the Portal is unlocked from Level 5 to Level 11.
- Update 2.4 introduced the option to upgrade the Ancient Portal to Level 7.
- Update 1.9 introduced the golden form of the Portal.
