So we know that the Pathian earrings are basically molten down Inquisitor spikes. But what abilities do they give? Wax doesn't seem to win anything when he puts his in, other than mentioning that he feels stronger in the mists (which probably doesn't have any link to this).
Is it just because they aren't in the right spot? Did they just assume that they weren't Allomancers and never tried it out? Did they lose their charge in the recasting process?
I'd go with the second or third hypothesis: even if the 1st one were true, you should be getting at least a few bronze Ferrings the same way as Vin.
Thoughts?
