Since Daily Rewards were introduced with Update 18, you've been able to acquire useful consumables, currencies, Crown Crates, and even pets, but during the month of September, we're giving you a massive amount of gold, too. If you log in for 28 of September's 30 days, you'll earn a colossal 100,000 gold. This is the most gold you've ever been able to receive for a single activity in the game (aside from Guild Trader sales, of course), and it has the potential to dramatically change your in-game fortunes!
In addition to the gold, September features a host of other incredible rewards throughout the entire month. Day 21 of September's rewards will grant you the Skald's Damask Jerkin costume, allowing you to don the garb of Riften royalty.

This coming month also features two Wild Hunt Crown Crates on day 7 and three 150% XP Scrolls on day 14, ensuring that September is set to be the biggest month of Daily Rewards ever!
Don't forget, to unlock a specific item, you must login and claim the prerequisite amount of days, first. When you log into The Elder Scrolls Online, you'll see your available item waiting to be claimed in the announcement panel. You can claim it right there or when you log out. You can also navigate to the "Daily Rewards" section of the Crown Store to claim your items, view future rewards, and see how many days are left before it resets. In order to be eligible for future rewards, you must claim your currently available daily item. If you do not claim a daily reward, the month's rewards will not progress.
