Hug the north wall of this area, taking advantage of the blisters and the patches of villi-less floor to let your light regenerate when you can. Up a small walkway a small way round the wall you’ll find the secret mural in this area.Guide not helping? View 1 more guide for this achievement.Leave a comment
