What Is the Biscuit's Anvil Event?
A Casual Event Based on Enhancement Luck
| Event Period | After maintenance on 8/6 (Thu) - Before maintenance on 8/20 (Thu), 2026 |
The Biscuit's Anvil Event is an event where you compete based on how many times you can Enhance a special event-only piece of equipment. Your rank is decided by luck, based on how many Enhancement stages you can reach without breaking the equipment, and you earn Ruby rewards based on your rank.
There's No Cost or Risk to Trying
There's a "Failure Rate" and a "Chance of Breaking on Failure," but both the equipment you Enhance and the material (Request Forms) are event-only items, so you have nothing to lose. Once you've stocked up on Request Forms, feel free to Enhance as much as you like.
Collect Enhancement Request Forms Daily
| Mission | Request Forms Earned |
| Daily Login | 10 |
| Clear Adventure 5 Times | 5 |
| Clear Raid 3 Times | 5 |
You can Enhance the event-only equipment using "Biscuit's Enhancement Request Forms," which you earn by completing Daily Missions. You can get up to 20 per day, so try to complete them daily. You also earn rewards based on your total Enhancement count.
Enhancement Request Forms Are Deleted When the Event Ends
Biscuit's Enhancement Request Forms are scheduled to be deleted after maintenance on 8/20 (Thu). They have no use outside the event, so be sure to use them all before it ends.
Success Rate Varies
You can access the Biscuit's Anvil Event from Events > Season Events > Biscuit's Anvil. As the Enhancement stage increases, the success rate decreases and the chance of the equipment breaking on failure increases. You can Enhance up to a maximum of +30.

Rank Rewards
| Rank | Ruby Reward |
| 1st | 5,000 |
| 2nd | 4,000 |
| 3rd | 3,000 |
| 4th - 10th | 2,000 |
| 11th - 50th | 1,000 |
| 51st - 100th | 500 |
For users at the same Enhancement stage, rank is decided by who reached that stage first, so it's best to complete Daily Missions and Enhance as early as possible. Daily Missions reset at 9:00 AM.
