Just wondering if there is anything you can add to the glass vial table to make more glass vials?
There is not, they simply respawn every day.
Yeah I was gonna say, just collect them from Jefferson’s table on the right of his camp.
Once you finish Ch3, you can get more behind the fog gate in the Northern Slurries. A second glass vial table, and the enemies in the Abandoned Labs have glass vials as combat rewards. But glass vials will always be a valuable resource.
