[Xietor]

Instead of gift of health healing mechanical beings,or a priestess, would it not make since that some races could repair them at a lab for resources or gold if a unit with a certain designation was present?

Say Ulm, Argatha, and other races that seem attuned to having mechanical beings, had certain units of these races could have a "repair" designation and fix things that are wrong with mechanical units, like missing arm etc. if a lab was present in the province.
