I think I am here.

So far nicrosil has only been shown to store Investiture in regards to abilities so not sure if this idea would work in-world. It's a super interesting line of thought though.

Hmm, your right, and since it is a really powerful ability, maybe the one I'm talking about can only be a thing for compounders. I'm imagining a someone trying to lash a compounder upwards, but the compounder absorbs it and channels the Investiture as breath, strangling the person with their clothes. It does seem cooler the more I think about it.

Look, I'm not completely certain, but if a Nicrosil Ferring stores Investiture, then wouldn't actively storing it cause the Ferring to become a sort of 'living aluminium'? As in they wouldn't be affected by any form of Investiture because they would be storing it? So, say if someone was trying to use emotional allomancy on a Nicrosil Ferring, it wouldn't have any effect, and the Ferring would store some Investiture. And again, if someone was trying to use any form of investiture on the Ferring, it wouldn't work and instead would be stored in the Nicrosilmind. In this way, when the Ferring would call on their Investiture, they could manifest it in any form (Breath, Stormlight etc.) Brandon has said Aluminium doesn't project an Atium shadow, and so, following the same principle, this Investiture-sucking person would probably make for an awesome assassin, storing any attempts at Investiture against them and manifesting that in different ways as weapons. In that case, I wonder what possibilities would open up for a compounder. I don't know, what do you guys think?
