Hello everyone! I have a question – how do I replace creatures in a town? For example, I want to replace the monks in a Haven town with free mages from NCF. Is this possible?

Replacing a creature is done by replacing two lines in the characteristics file – character visual and map object (I can't write it more precisely without a computer).
Copy these lines from the mage's characteristics and paste them into the monk's characteristics, then find the map object and the monk in the data.pak file and copy the bottom line, like CHARACTER PRIEST, and paste it into the corresponding mage file.

Or you can rewrite the path to the mage file from CharacterVizual/free city to CharacterVizual/haven.
And rename the files inside the folder so that the game recognizes them as monks; do the same with the map objects. The last point of the first method also needs to be done.
