OK...Thanks everyone. Especially Wish....for the laugh about the sneeze comment.
Now...I hear talk about a "Dominion Kill" strategy. I think I understand that if your Pretender has no more white candles on the map....Dominion?....then you lose. Is this correct? And is this what is meant by dominion kill? And how does one achieve this? By temples and strong priests preaching? Or I assume....more likely...some sort of strong dominion dominant spells?
I don't think you can rely on dominion kills... even the AI can usually prevent them. Sometimes an AI will have a low dominion though and will just die out.
You need to be careful it doesn't happen to you, of course. Build temples and preach if you see your dominion getting too low. If you start next to a couple of enemies with high dominion things can get a little troublesome early on.
My main use of dominion kills is to avoid storming heavily defended castles. If I conquer most of an enemies' provinces and build temples there then I can preach in a few besieged provinces until his dominion dies.
