How to recruit a level 8 monster in your "home" castle.

Can you tell me what I need to do to make level 8 monsters available in the "home" castle, where level 7 monsters have been built and upgraded?

Otherwise, according to the description (see below), I can only buy a monster once - when I capture its dwelling.


New level 8 monsters
Level 8 creatures are divine in origin, so they cannot simply be hired in a castle like other units.

To get them into your army, you will have to do the following: first, capture the building where they live by defeating two or three of them in battle. Immediately after the battle, you will be able to hire one of these fighters. Keep in mind that this opportunity is only available once. After that, the monster dwelling will be empty until the end of the game.
They can be hired in any city belonging to the player, where a building for level 7 monsters has been built. The number of level 8 monsters available for hire depends on how many of their dwellings, scattered across the map, belong to the player. If you do not hire all available level 8 monsters this week, they will simply disappear at the beginning of the next week, and will not be added to the newly spawned ones. Note that you can only hire a level 8 monster in a building for level 7 monsters.
