I decided to try my luck with doing Fisherman's Stall. After an hour of trying to get skill ups, nothing. Am I missing something like a test or this level range is just that slow to skill up on Stalls?
Are you feeding fewell for an element used in that synthesis? You won't get skill ups unless you're feeding relevant fewell.
unfortunately, the stalls are 99 of a single element. if you spam it, you will get too 99, and when the furnace HP hits zero, it will complete the synth. at least thats what happened to me
