This glitch allows you to freely travel through Eternal Battlegrounds w/o anyone in sight, no walls on castles, or npcs. This is not an exploit or something you can benefit from, but it was a cool find to come across of.
Requirements:
Midnight v2 or v1 in order to teleport. No need for noclip for this to work.
In WvW: Eternal Battle Grounds
1. You want to travel to the Obsidian Sanctum (where the chest is located). This can be accessed by going through any mystic portal on the map.
2. Make sure you are on the middle/central platform of the three platforms.
3. Use teleport to cursor through the mystic portal
4. You should now be half way through a mountain, so continue to teleport yourself outside of it until you are then on top.
5. Have fun exploring and using your hack w/o the worry of having people report you!
