I tried to get some XP by angering big ammount of waves in endurance to 1e300 and beating them with shrines. Unfortunatelly, I've angered little too much and got infinity HP wave. "Don't worry, nothing bad can happen in endurance" - I thought. But after hitting some of these infinity HP monsters with shrine of blades game just freezed and I've lost all of my 1e12 XP...
