Walkthroughs for custom maps.

Has anyone played the map "A Long Way Ver. 1.3"? How many "Amulets of Sea Providence" are there on it? I only found 2, but it turns out there are three guardians on the map that require it. One guardian can be ignored, but behind him are some useful objects.

P.S.
The first amulet is located in a dungeon at point 17, 53, 0.
The second amulet is located in the underworld at point 125, 22, 1.
