Build a Shaman's Hut. Notice that this doesn't let you build Shamans but instead gives you a Fire Eater for some reason. Adopt Sedentary -> Double build rate of Huts and Cave Drawings
Easily pump out a Shaman's Hut every turn, and sell it for 12 gold. Acquire a growing stockpile of gold until you have at least 12 Fire Eaters, and then some more. Spam them against your enemies, surrounding his lands, starving him, destroying all his units, and get a blank cheque peace.
Other weird things. Techs claim to reveal Bison or Deer or other resources, but I can see all of these from the start of the game. The Creation Process randomly provides health like the Healing Process. And I can't build Shamans.
