2 times I re-caved. On the first week it was tough, almost lost to the computer. Few Dragon Fly Hives spawned and I didn't see any Conservatories at all. I wanted to dig up the Grail but the HeroesWorld rules don't allow digging, and we agreed - digging is allowed on day 131.
I took the first Dragon Utopia on day 141 with the Book of Earth and nothing else useful. The 2nd Utopia was a teapot in terms of useful stuff, and the 3rd gave me Dimension Door and Fly in the form of a level 5 hat. I immediately jumped to the opponent and killed him.
Thanks for the game!
