I spend three and a half minutes opening a chest (Calm Spirit), only to find an item I can do nothing with. I don't really bring items into the trial with me, so having a chest with basically nothing in it, sucks.

If chests need to have the chance of spawning something useless, may I suggest the following:

1. All chests have a knock-off Zelda chest theme.
2. When you open a useless chest, you get the Zelda theme performed on a kazoo.
3. Useless chests have no item, but instead the chest releases some Clown gas and the sound of the Clown's cough echos throughout the map.
