‘Arthdal Chronicles: Three Forces (hereinafter Arthdal Chronicles)’ has rolled out its latest autumnal offering, the 'Jackpot Challenge Box: Autumn Glow III'. Opening these boxes yields various grades of 'Jackpot Challenge Coin: Autumn Glow III' based on drop rates, which you can then use to craft items. There are some excellent rewards available, but many players are missing out simply because they don't know the system exists. So, KookminTree has broken down everything you need to know about these Autumn Glow coins.

Q. How exactly do I get my hands on these Jackpot Challenge Coins?
A. You can buy the boxes for 100 Gems each or just scour the Exchange.

The most straightforward way to grab these coins is to head to [Shop]-[Items]-[Special] and pick up the 'Jackpot Challenge Box: Autumn Glow III'. Each box costs 100 Gems. Upon opening, you will receive one of the following: Radiant, Resplendent, Shining, Superior, or Normal Jackpot Challenge Coin: Autumn Glow III. These coins serve as the primary currency for your crafting needs, though you are free to sell them on the Exchange if you prefer.

In other words, if you’re hunting for a specific coin, you don’t have to play the odds with boxes; you can just buy what you need directly from the Exchange. While cracking open a mountain of boxes is one strategy, those with specific crafting goals should just hit the market. As of October 19, 2025, market prices are hovering around 2,500 Gems for Radiant, 850 for Resplendent, 300 for Shining, 100 for Superior, and 30 for Normal coins.

Q. Which items should I be crafting with these coins?
A. The Legendary Summon Selection Chest I is your best bet.

So, what’s actually worth the effort? First on the list is the Legendary Summon Selection Chest I. It requires seven of each coin type, but it lets you pick exactly which Legendary Summon you want. Given the current Exchange rates, that’s roughly 26,000 Gems for a guaranteed legendary—so if your coffers allow, you can craft up to four of these.

Next up are the Gems. Each craft requires one of each coin type, with a server-wide limit of 10 crafts. A word of caution, though: don't use a Radiant coin to craft 3,960 Gems; you’ll end up losing value. Stick to using Resplendent, Shining, Superior, or Normal coins for this. Of course, markets are volatile, so if the coin prices spike, do the math before committing.

Q. Is there any way to trim down the Gem expenditure?
A. Make sure you’re utilizing the Gem Item Discount Coupons.
