Players can fight with each other on the Grand Arena as well as on the common Arena. Grand Arena becomes available at team level 50.
You fight with three squads on the Grand Arena (not one). Each fight consists of 2 or 3 rounds. The player who wins in 2 rounds wins the entire battle. Battles are in automatic mode. If there is no winner after time runs out, a defending player wins.
In the Grand Arena window you can choose the defenders' squads, 5 heroes max in each of them. The heroes can be of any lvl (even 1st).
In the main window you see the sum of power of all your squads:
To make changes in the squads click "Change" button. You will be able to allot your heroes to squads. The power of the selected squad is displayed in the left bottom corner:
When searching for an opponent you won't be able to see all three enemy's squads: players ranked 100 to 21 have one team hidden, players ranked 20 to 2 have 2 teams hidden, the player in the first rank has all three teams hidden.
But in all cases you can estimate the power of the entire team:
There is a 10 minute cooldown between battles on Grand Arena. You can skip this cooldown for emeralds.
You will receive a special currency - Grand Arena coins. They are accumulated in real time. The number of coins you receive in an hour depends on your Grand Arena rating (the higher this rating, the more coins you receive). You may claim earned Grand Arena Coins at any time.
The everyday Arena reward is given for higher place on either Arena or Grand Arena. For example if you have 10th place in Arena Rating and 5th place in Grand Arena rating, you will receive a reward for 5th place.
NOTE: To access the reward you need to fight at least 1 battle that day before awarding.
