I am a wizard, and I just realized that... bags of holding reduce the weight of items in them. Good to know! So, my question is does a bag of holding reduce the weight of items in it if it is inside another container?
Also, do bags of holding reduce the weight of items which are themselves inside another container inside of a bag of holding?
What exactly are containers vulnerable to? I have a greased sack inside my bag of holding. Does this afford any extra protection for items inside the sack? Can anything happen to any container (including boxes and chests) while I cavort about?
