The rune boss appearance rate seems to be very low since 2 days ago. Hardly find a rune boss despite doing advance and extreme tower. On average every 7 to 8 kills advance give 1 rune boss and every 5 to 6 extreme 1 rune boss. Better keep the crystals for future events, seems that developer aim for this event is to deplete your crystal stocks so that you buy more and more.
