I'm working on a new player's guide which includes a sample starter build for each class, designed to be simple and easy to play. Having never played a Cleric before outside of dipping one level to get Heavy Armor on my Wizard, I'm not sure which domain would be most suitable for this purpose. To be clear, I'm not looking for the most powerful domain, I'm looking for a domain with simple and easy to understand abilities. PHB options are preferred over XGTE or DMG ones.
