The most honorable way to regain access to a hermit is to use a bomb and destroy the cave on the island where the hermit has been kidnapped. Kidnapped hermits will be inaccessible and cannot be recruited again from their cottage instead, they can be rescued. This section is about Kingdom Two Crowns. Kingdom Two Crowns – A monarch can manually dismount a hermit, by flipping back and forth rapidly.

So, other than giving to towers a special ability, the Monarch may want upgrade them for the simple purpose of releasing these archers either because of economic needs (if the number of archers hunting is insufficient), or because the outer wall has advanced and these towers have little use as defensive structures. When a tower is upgraded with a hermit, the archers on that tower are released and return to their regular role of archers, hunting during the day and guarding the outer wall during the night. Kingdom Two Crowns – You don't need to have them with you in order to carry them to the other islands: all hermits alive on the island will come with you upon departure. They can also be taken to the next island, if you have them on the back of your mount when you sail with the boat. You just have to pay one coin to have them ride alongside you again, but if you go in the wrong direction they will jump off again. They will jump off your mount if you go outside the borders of your kingdom at night, so be careful.

The hermit must be riding alongside you in order to upgrade a building.
