The Daily Bonus is a prize you get for logging on to the game on a daily basis. If you play the game for 5 consecutive days, you'll have a chance at getting up to Super-Rare armor. Other prizes include Gems, Uncommon Armor, Crafting Materials, Arena Energy and Gold.
Starting in mid-2016, the rewards on a daily basis were changed entirely to Gems. The number of gems you can receive increases each day. The rewards are as follows:
- Day 1: 1 or 3 Gems
- Day 2: 2 or 6 Gems
- Day 3: 3 or 9 Gems
- Day 4: 4 or 12 Gems
- Day 5: 5 or 15 Gems
You also receive one Enchanted Chest Key per day.
