Convert an enemy Monk.In order to convert an enemy monk you will need to be playing as a civilisation that can research the 'Atonement' technology. Then you must use your monk to convert an enemy monk. An easy time to obtain this is during level 3 of the Saladin campaign. The relic that must be captured is walled in and has 3 monks in this area who cannot escape so you can convert one of those.
