While there are a lot of puzzles I dislike and some i have asked for help or googl'ed; this specific puzzle I did on my own and it was quite easy so I don't think i would call it idiotic. I did the first three easy; I was really worried that the last one was going to take a while to guess but then I found an item in the room that was the exact weight I needed and it was obvious when I found the item as to the usage. The two puzzles I found really painful were dodging the death knight (who have very long vision and run very fast) and the mirror (one of which is hidden); oh yea and the 4th button in the chapel (found 3 but not the 4th).
Thanks for this post. This is quite possibly the most idiotic puzzle I've seen in a game.
For anyone stuck, to summarize the weights are: 1, 2, 5, 7.5 from smallest to largest button.
