have you completed the Quest for champions that needs to be done ? to get to the hunt?  it might just take you a few clicks to get your hunt But I wouldn't start it Until the champions tourney starts (If it was me ) and when you do start it Make sure you study the Mechanics of the feature before you set it and forget it. One last note solo hunt will use all of your Energy and Emeralds  if you set it on auto recharge and leave it way beyond what it takes to max the champion to its highest possible level. so be careful
