Walkthroughs for custom maps.

In that thread, please formulate specific questions and ask them. It's impossible to answer vague requests like "Help me with a map!" with a single word. However, you can get an answer to questions like "Where can I find a specific artifact?" or "Where/how can I learn a specific spell?" or "How can I defeat that enemy hero?" In the last case, it's highly recommended to attach a save file with the current situation (in the extended editing mode, which you can switch to at the bottom; attach the file using the paperclip button).
Also, we don't know anything about your skill level or which maps you have already successfully completed. You can also write about this so that it is clearer where to start the discussion.
