Oracle oracle

  The oracle is unlocked with the [Oracle](\minedefense\wiki\Upgrades#oracle) upgrade. It shows the amount of time until the next goblin and spider attack as progress bars surrounding a crystal ball, and hovering over the graphic will give the number of seconds remaining until each attack. It will also show the amount of time remaining on traps and lures if any are active. Clicking on the oracle opens the oracle teaching page that provides helpful hints for what to do next at each stage of the game. 

## Oracle teachings

The following is a list of all of the teachings, the requirements to pass each one, and the purpose for the teaching.
