This happens in the pirate cave in the area with tons of switches. I used this switch (arrow) and a chest appeared. I opened the chest and found some gold and a pair of non magic shoes inside. I loaded the game and now I received 10 points of damage when I try to open the chest. I bashed the chest and got the same items as in the beginning.
I can understand if this chest is a trap (This area is full of traps.) But it should do the same thing every time.
