what's the purpose of the left click option?

Since there isn't one Make-x where the Blessed Flask creation happens vs. something like with Masterwork, the left click option is essentially the instruction on where to go whereas the examine here was reserved for the reference :D

For a few ingredients for the Blessed Flask this is done via the left click or the examine, for example the Blessed Sand's examine.
