The Medallions Can't Become the Bands of Mourning

The medallions can't become the bands of mourning. You can't make a mistborn with these medallions. I'm really interested to see like what is the reason for these limits because right now, even a three power medallion would be better than anything we've seen in era two. And if you could add one more, so I give wax one more power, that would be incredibly potent. Yeah. If it has something to do with like, you need a pushing and pulling or you need ones that can all be too close or too connected.
