Repair costs? Money for monk medicine?

Greetings People,
I played the closed beta but I don’t recall if repairing boats, buildings and siege units costs resources… does it? Regarding healing is there a resource cost associated with it or is it a gift from the Divine? Healing was free of charge in earlier games but once in a blue moon things change and such.

Repairing costs wood. Healing units is free. Not 100% sure if fishing boats healing other boats is free or costs wood.

Thank you for the reply. :+1:
