Healing
The second tier of the muhafaza branch; its prerequisite is Banners.
What it unlocks
It unlocks Physician and Hospital. Both touch healing and morale recovery, but their reach is separate: the Physician is a mobile support that heals adjacent friendlies even outside your territory, while the Hospital is a fixed building that only works inside the region of the city it is built in (Morale and rout).
The node also raises the population cap of all your cities by a step (Cities and population): capped cities grow again and the food waiting in the granary flows to them.
When to research it
This node is the prerequisite of the doctrine node The Hearth — if you want the muhafaza doctrine, you have to pass through this node. If you play an army that stays across the border for a long time, the Physician's out-of-territory healing alone makes the node worth it.
