So I know my name is PewterAgoldF but I was thinking about what I would do if I was double nicrosil and had some thoughts
Firstly this is probably the rarest combination there is so lets just say Harmony gave me some specks of lerasium I could alloy with whatever I want (not enough to become a mistborn) and another bead that does the same for feruchemy somehow (perhaps lerasium+atium+another metal, idk)
Secondly, since I can now compound investiture, could I potentially get a Pathian earring, made from old inquisitor spikes, and take the miniscule residual investiture from it and compound that? Steel earrings could hold Pushing and Pulling and Pewter allomancy, and Pewter earrings would probably have feruchemical gold, possibly speed.
Thirdly, in the same way that you can't compound if you got your feruchemy and allomancy through hemalurgy because it is being performed with the spiritual signature of the victim, does that mean that as a nicroburst, I could nicroburst my own allomancy which I got through hemalurgy? Or is the signature thing only for feruchemy?
And lastly, could I compound the investiture of hemalurgy taken from regular people? For example a tin spike doesn’t give allomantic or feruchemical tin ability, it just gives you better senses permanently overall, then as a nicrosil compounder I could tap as much as I want at will. This could go for strength (try not to koloss out), mental strength, and emotional strength too, and a duralumin spike grants faster burning ability I think (not instant burning of all active metals) so compounding this would be way more useful than actual allomantic duralumin)
I see only one issue with the last one (apart from potential craziness) being that if the power is not of preservation then how could allomantically burning it grant more E.g. if I somehow get pure Ruin investiture I don’t think I could compound it because preservation doesn’t have ruin investiture to give. But maybe the senses taken from regular dudes still has preservation in it.
Look forward to hearing your thoughts.
