I got rioter, doesn't seem like there's that many of them. Yeah! But it does fit, I like to get people to tell me what I wanna know and I'm already pretty good at it so now...

Okay, thanks for clearing that up

So the obvious answer is the ability to burn specific metals or alloys to gain temporary powers. But I'm asking what IS it? Mistborn can burn metals to gain amazing powers like physical strength, but how? Cause later in the mistborn books we see that on Scadrial the links to the spiritual realm are metals, so much so that Scadrians (which aren't really humans, they were made after the shards were a thing) have tiny metal spikes in their bodies just naturally. Metal in Scadrial works much the same as stormlight works in Roshar (which brings up the question of whether a coinshot in Roshar would still push metal or would change to things infused with storm/voidlight but that's for another time). Anyway does that mean that allomancy is the act of digesting investiture? (It's unclear if it's a purely Preservation based power as burning Lersium grants allomancy or if scadrians' Ruin investment mixed with the burning grants the power). It could work in a way similar to the way Lift can turn food into stomlight (investiture) through the boon granted to her by Culivation. Anyway I'm rambling way too long and I'm sure I've missed some stuff but I wanna hear other people's theories.
