Island of a small skull

The map is interesting, but there is a major flaw and some minor shortcomings!!! ...which makes it easier to complete.
Firstly, the towers with questions are placed poorly, which means you don't have to fight Sandro, and the portal to another dimension appears in the middle of the game (after capturing the Grevraven Castle)!
Also, there are too many artifacts. You can collect the composite artifacts multiple times (( But overall, the map has a good idea! Thank you!
