Author, you could at least have mentioned that the dungeons are random; how are regular players supposed to know that? Add a marker before the dungeon with a description, or in a text document.
Why is the buff located in such an inconvenient place? You could have added more chests in the sea, branches, etc. Why put just one oasis in the desert? Too many questions...
