Tower is a game mode where the difficulty of battles increases with each floor you climb. The main feature of this mode is that as you progress through each floor, the power of the enemy teams increases, and your heroes do not recover with the start of a new battle.
You have 24 hours to complete the Tower . The higher the floor, the stronger the enemies. The strength of the enemies depends on the parameters of your account and increases in parallel with the heroes' upgrade!
In order to defeat enemies, you need to choose the most resilient team of heroes and think over a battle strategy based on the characteristics.
In the Tower, the heroes have only one life left, which means that if you received damage during the battle, on the next floor, the damage done to the hero will also be displayed in the next battle. If the hero dies, they will be unlocked only after Tower restarts.
Tapping the green button in the upper left corner of the screen you can restart the Tower. It does not matter whether you finished the Tower  or not, it still will be restarted.
In the lobby your enemies are presented. You can click the icon of any of them to get acquainted to their stats.

Pressing the Cart button, you'll be transfered to the Shop, where you can use Mystery sapphires.
