Win Streaks are a bonus system in the Arena designed to increase rewards for consecutive wins.
Rewards increase by 10% for every win with a maximum bonus of 10 consecutive wins, for a total bonus of 100%. Win Streak Bonuses will increase the total points and coins earned from a victory and will also increase the drop chance of Greater Epic Stones and Hero Tokens.
The timer lasts for 15 minutes and begins counting down immediately after your latest win. Losing a battle will end your streak, even if there was time remaining.
