While you're just hangin' around, I might as well get you involved in my whole beer-makin' "process". Ain't muc of a process, really... I just mix all the stuff together and wait.
You probably heard - I like to use the muddy water from the riverbanks, to the south. Would you mind fillin' up this flask with that water and bringin' it back? I'll start gettin' the hops and barley all ready.
Mudmug's vial will slowly spill water while you are moving. Plan your path carefully!
Travel roughly south of Mudmug's Place to the river. There will be patches of sparkling muddy water all along the stretch of river. A vial will appear in the bottom middle of the screen showing progress.
Each path will usually contain multiple nodes, up to four. Before beginning, make sure you are near a cluster of them, as each time you move, some of the muddy water will spill from the vial.
Once filled, you no longer have to worry about spilling.
