I had no idea! Wow, thanks for tip! I will try to fit my 5’3” 57kg woman through that crevice when I find it.More power to you! FWIW, if you make your Arisen petite enough, there's a hidden little nook in one of the game's major locations that you'll be able to access. There's nothing terribly important there. Just an alternate way to traverse the area that larger characters won't fit in.
Kindly accept my gratitude for your help and for acquiescing to my friend’s request.
