Random Button

**Every press is a surprise.** Random Button creates a protected lobby with a button that
  triggers an event each time you successfully activate it. One press might shower you with
  useful loot; the next could bring hostile mobs, TNT, or a falling meteor.

  Events range from weather and time changes to status effects, themed loot, unusual traders,
  structures, and dangerous encounters. Face a hostile Mirror Double wearing copies of your
  equipment, escape a buried lava pyramid or anvil trap, or survive a fall into a temporary
  cobweb shaft. Some events change the terrain or remove items, so be ready for genuine risk.

  Lucky and Unlucky Cubes let you influence what comes next. Each cube adds five charges for
  beneficial or harmful events, and the HUD shows your remaining charges. Every 20 successful
  button activations awards a random cube. Use the recall sigil to return to the lobby.
