As far as I can tell, you are wrong again. Sylvan Elixir and Lightblood Elixir are the two outdoor items being referenced, and they are still usable. I can’t find any patch info citing them being disabled, but I do see guides as late as May 2018, over a year after the initial Mage Tower release, advising people to use them for Agatha before the Mage Tower appearances become no longer obtainable.
Is there a reason you don’t fact check yourself before posting blatantly false information, over and over again?
