Ranger - "Higher Vampire" [5th Campaign, 5th Mission]

I found the first 2 artifacts, but where are the other 2? Could someone please share a map of the dungeon and a save file for version 1.60?

To find something, the easiest way is to save the game and then enter the following commands in the console:
@ClearCircleFog(0,0,0,9999,PLAYER_1); for the surface
@ClearCircleFog(0,0,1,9999,PLAYER_1); for the underground

The artifacts on this map are hidden behind blue garrisons, so they can be easily found on the map by the blue squares.

Don't forget to load the save file back to avoid feeling like you're cheating :)
