I like to farm, including items to upgrade. Including the from Bosses (Watercrystal, Blue Crystal,).
Since the bosses throw a large heap of drops it is decidedly difficult to find the object, I think that sometimes I have overlooked.
Of course, these are just examples items because I'm currently farming them.
That's why I ask you as comunity under this post to comment on which items you have your problems so that we facilitate the relevant work and not always come back to it.
Of course it is only my opinion and I would like to know what you think of this idea.
That's why I ask you as a comunity what you think of it and you answer under this post and eventuel also describes your "farm problems".
In this sense, have a nice day and good luck farming!
