I'm a little confused as to what the new apostle actions do. The ones I currently see are:
- Evangelise belief
- Launch inquisition
- Spread religion
I'm also wondering how you heal an apostle?
Their actions in order:
Apostles (or either of the other two religious units) can only recover HP on (or adjacent to) Holy Sites owned by the same player who owns them, though not necessarily in a city of their Religion. Move the unit onto, or next to, a Holy Site and sleep / skip turn until they're back to full health.
