Guild Wars 2

Last place I was missing was the bottom right corner of Straits of Devastation, the “Sea of Elon”. Seems obvious but there isn’t really any reason for you to swim there (unless you chose another story path perhaps).

I had already explored Chantry of Secrets, after reading this I zoned in there again and I got my World Completion awards (2 Gifts of Exploration).

My achievements are at 175, 59, 163, 170, 179. People in this thread are all around the same amount, but notably they are varied a little bit. When I was 100%ing I made sure I hugged the edge of zones etc to uncover the map so I am not sure where the rest are. Dungeons perhaps, specifically explorable mode.
