Brawl is your basic grind battle. There's no limit to how much you can Brawl, only how much time you have to play. Opponent matchmaking is the most balanced in Brawl so your opponents won´t depend on your actual league, but on your maximum reached league and your might.
There are 7 different rewards possible, chosen somewhat randomly for each win.
- Gold - The most common reward. There is a small chance for the gold reward to be multiplied by 110%, 120%, or 400%.
- Cards - Either a larger amount of Common cards, or a smaller amount of Rare cards. You cannot win Epic or Legendary cards.
- Pal Points to soulbind your heroes.
- Friend Coins used to gift daily to your friends.
- Journey Keys: You can win up to 3 Journey attempts from a single battle.
- Ancient Coins to buy in the Journey Shop .
- Dark Coins to buy in the Dark Shop .
Protip: Although rewards aren´t big at all, if you are a VIP player, you can autofight Brawl Battles
Protip2: Brawl fights are specially useful when you are in an Event, as you can get more Journey attempts in the same day.
