To participate in this test, you go to an Essence of Harmony and make a guess as to which player will pass many tests. You can make as many predictions as there have been weeks since the Test began (e.g. in the 11th week, you can have a maximum of 11 prophecies). You can make a new prophecy every 24 hours until you have as many prophecies as weeks since the Test began, thereafter you can only make one new one per week. This lets people that started late or missed a few weeks catch up with everyone else to some extent.
You cannot predict yourself and you cannot change or delete a prediction. Be careful when selecting - betting on someone who quits a few days later (or typoing a name) blocks one of your prophecy slots forever.
You gain 1 point for each test the person passes after you pick them. Points continue to accumulate as your picks pass more tests. Those with the most points each week pass the test.
