Hospital allows treating wounded troops so they can again become part of the army. This allows quicker rebuilding of losses after major battles. It’s not cheaper to heal; the costs are the same as for training new units; however, the healing time of wounded troops is half that of training a new unit.

What are “wounded” troops?

• When units from a village with hospital take part in battle, 40% of their losses return to the village as wounded.
• This works in all battles, whether they attacked, defended or were reinforcing another battle.
• Using bandages (hero items) do not affect this. For example if the army had 100 losses and hero used 33 bandages, 33 units will be recovered while 40 will become wounded.
• Siege engines, settlers and administrators cannot be wounded. Hero is also not affected by the hospital.
• Troops killed while escaping from traps also do not get wounded.
• Only units from a village that has a hospital at the time of battle may become wounded, otherwise they die as usual.
• Wounded unit cannot fight, but they also don’t eat crop.

How can you heal wounded troops?

Hospital has a healing queue, that works in similar way to training queue in barracks or stable. Healing a unit costs the same as training new unit of that type. The time to heal depends on the level of hospital and is twice as fast as training. For example hospital at lvl 5 heals units in half the time as barracks/stable on lvl 5 train new units. However, the hospital is not affected by any bonuses to training time (like hero equipment, artifacts or alliance bonus). Both infantry and cavalry are healed using the same queue.

What if you don’t heal wounded?

10% of them will die each day. As soon as you add any unit to the healing queue, it cannot die anymore.

An example of healing duration

• A Barrack lvl 20 builds an Ash Warden in 80 seconds.
• A Hospital level 20 heals a wounded Ash Warden in half of the time aka 40 seconds.
