Collect Trophies to reach higher Raid Tiers. The chance for improved loot from the Wanted: Heroes mission chests increases as you reach the higher Tiers. The rewards from this chest are based on your current Raid Tier at the time of the chest collection.

The Raid Tier you are placed in depends on the number of trophies you earn.

At the end of each Raid Season a player's Raid Tier is rewarded based on the highest Tier they reached during the entire season.
