You have two magic vials that have a percentage chance of filling on the first of the month, which just happened.

1- Jade Confluence Container: 75% chance to fill with a Ki Confluence Potion
2- There's some restore potion container that has a 25% chance of filling. I'll get the full quote later.

We need to remember to roll these next time, as both have been empty since you gained them.

I actually remembered the restore potion refill, but I didn't think you told us that we hit the first a new month. I remember you mentioning day numbers in the mid-20s. Maybe I just missed you telling us that we rolled over to a new month.
