Current questions and answers regarding the map editor.

What about the Amulet of Ascension, do you know where to find it?

You can find it somewhere near the end of the artifact list. It looks like a blue cube with text in English.

Can I ask a couple of questions about the editor?
1) Where can I find the scripts for maps like in the campaigns?
2) Please, tell me how to make the ground visible in Dungeons? I can only see the objects.
3) How do I delete rivers?
