I would like to see the UFSG mention or included somehow in the tutorial. All new players seem to use wiki. The wiki isnt up to date on the early map and more confusing than helpful.
I was inferring that Wivja was trying to get the best rate of composing XP. Wivja's example does only give 20 XP per potion, but the potion takes (for level 2) 90 minutes to compose. A level 60 60 minute potion takes 95 minutes for the same 20 XP. On the other hand, a level 120/120 minute potion would give 30 XP, but would take 155 minutes, so 63% longer for only 50% more XP.
But then again, I might have completely missed Wivja's point
You got my point completly. Of course overnight or when Im going to be away from computer for many hours I do. 300 min pots with 501 skills points for 70 xp:) Or if you are level 1 or 2 you should do 268 min with 268 skills points
