Bags are a Special Loot item that works just like Chests, but don’t contain blueprints and are not trade-able. Additionally, they are FREE to open!
You can earn bags by completing quests, finishing the Daily Objective for 7 days in a row, and in the Arena! You can store and open bags later in the Chest room!
Bag levels are:
Treasure Pouch
Mysterious Bag
Wonderous Bag
Champion Bag (only available in the Arena)
