Sanity Supply is a special distribution event where 3x Emergency Sanity Boosters are sent to your in-game mail every day at 12:00 (server time).
The mail can be claimed from 12:00 to 11:59 (server time) the next day, and the items will expire 7 days after you claim them. Be sure to log in and open your mail so you don't miss out.
Important Notes and What to Do
- Get an Extra 120 Sanity
- Need to Log In Once a Day
- Emergency Sanity Boosters Have an Expiration Date
Get an Extra 120 Sanity
With Sanity Supply, you'll receive an additional 120 Sanity per day, in addition to the Sanity that regenerates over time. This allows you to gather more character progression materials than usual, so take this opportunity to farm what you need.
| Tip! | As long as you claim the items from your mail, it's possible to save them up and use them all at once later. |

Need to Log In Once a Day
The mail is distributed when you log in between 12:00 (Server Time) and 11:59 (Server Time) the next day. You won't be able to claim the previous day's mail once the next distribution period starts, so make sure to log in daily.
Emergency Sanity Boosters Have an Expiration Date
Emergency Sanity Boosters have an expiration date. If you don't use them before they expire, the Sanity they provide will be wasted, so be sure to use them before the deadline.
Best Ways to Farm Materials
Farming T-Creds Should be Top Priority
T-Creds are required for almost every aspect of upgrading and strengthening characters. If you're not sure what to farm, T-Creds are a safe choice since you always need them.
Check Rewards for EXP Materials
Your second priority should be EXP materials. Since there are multiple types of them depending on the level of your character, make sure you are farming for the right one.
Farm the Protocol Space
Although the Sanity cost is discounted, the rewards you get will stay the same. Prioritize the materials you need for the characters you are currently using.
