You know how you are going to implement rope to hold ghosts down?... Well it just occurred to me that a lot of ghosts are famously susceptible or weak to iron... 
"Cold iron" is historically believed to repel, contain, or harm ghosts, fairies, witches, and other malevolent supernatural creatures...

So with that being said, It would be awesome if you included Iron chains or shards as one of the useable items in game even if you have to replace something...

This idea was just too good not to share. Really hope you do 💜^_^

Will think about that if I find a unique method to use that tool.
