Idk if people have known about this spot bc I've explored the VoG quite a bit and just discovered this spot a few days ago. It's in the top part of the Templar room and you get there by jumping up into a little room above the right conflux. I'll try to make a video and link it since my explanation kinda sucks lol. Just curious if people knew about this room and checked it when they were trying to spawn a new chest.
