Synergies add special bonuses to your Champion team. This includes extra stats like health, critical, block, power, armor, or even unique abilities. To check the bonuses of your Champion, access the Champion's INFO button, and then tap on the SYNERGY BONUSES section. Champions trigger bonuses based on their relationships with other Champions. Some bonuses will be unlocked with higher tiers (stars) of your Champion.
When the owner of the bonus is paired with the required Champion, the bonus activates for everyone on the team. While building or editing your team, tap on their synergies, and select a bonus for more information. This will display all available bonuses for that Champion. If the Champion required for the synergy to be active is available in your inventory, you will be able to drag and drop it to your current team.
Make sure that you match the correct Champions to gain an advantage in battle!
