Is finding Sketamari before getting its drop, locked to a base game Standard Character, or some other condition?
Like how I couldn't find Random with Menya Moonspell and had to use Zi'Assunta Belpaese to get them?
I walked the way said in guides with Suor Clerici for basically the whole 30 minutes, with the Merchant to mark my starting location, and no Sketamari appeared. I walked:
South
My last guess is that I have to get the Yellow Sign before I can find Sketamari? Especially given now that I have the Sign myself and the "Find the Drop" achievement is listed.
But, given how far the Sketamari travels, and how thin it is, I could've just missed it every time.
