1. What is the most effective way to stop a dominion-loss once you are already far into the game?

If you are in serious danger of being dominion-killed, then put your pretender AND prophet together into a province with a temple. Unless your dominion is horrifically weak, that should give you one province with unbeatable dominion.

Clustering your temples together might help also. Not entirely sure how the temple conversion checks work.
