"There are only 56 gold vials remaining, which would last all eight of us for seven months, and three platinum vials, supposed to last at most three months each, up to one year and four months if we used them consecutively. However, if we utilize them sparingly, it isn't hard for us to stretch it up to two and a half years, or even three years if we want to stretch," Leif responded.
The depletion of each vial depends on how many times they had activated it to use the Vylkr energy within it.
However, it isn't wrong to say that due to the constant attack of the Vylkr vines, as long as they have fixed the vial into their Devourer's bracelet, it will always be activated.
So, to save the number of vials they had, they would need to cut down their usage, and that also meant making some sacrifices, which he was sure nobody present wanted to make.
