I attacked a village and thought I could use my healer on the dragon in my cc (my friend donated it to me) but it did not work. Looks like healer only heals ground army. If I take healing spells, will they provide healing to dragons if some archer or wiz together are attacking on him or not. I only have 4 spell space, so I am thinking of taking two heals. I dont have rage yet.
Yes, while a healer will only heal ground units, heal spells will effect both flying and ground units provided they are not being damaged by an inferno tower as infernos towers block healing effects.
