Yes, I got a bit lucky with the sacrifice. I didn't expect it myself. I was already mentally prepared that I would have to fight Nilu in 2 or even 3 rounds, but she gave me such a nice advantage.
As for other maps, it's unlikely. Unless Paragon 3 comes out in the near future. :D
I play purely for fun, and I don't often start new maps. And difficult maps also take up too much time.
