Changing a skill in a campaign.

Why not watch a video guide on cheats and see if you're entering them correctly? Maybe you forgot to enable cheats.
This is a mod -> https://m.vk.com/wall-87790524_14806 But you'll have to start the campaign over with it, so try using cheats!

I'm amazed at how people have forgotten how to use Google. Why, I wonder, did I immediately find the right mod on the second suggested site? 🤔 Probably, I'm a wizard.
