Thanks Game! That clears up pretty much all doubts!
Like frigide, I'd also be very interested in finding out what triggers the timer - does it start when you open the portal to cruci lvl 2? Does it keep going if the leader is in town? Also, Lampogriz mentioned that the 15-20 timer is broken. Does that mean that we can take our time after we clear lvl 14/15?
Thanks!!
