Healer

Healers are additional men who travel with your unit. They don't fight, and have no benefit during combat. It's after combat that healers do their work. Healers treat your wounded men. They can save wounded men from dying, and return wounded men back to duty faster. Each healer can only treat so many men, so make sure you have enough healers for your troops. Healers can only be recruited in regions that have Houses of Healing.
