Hello y'all,
Ok, I know there are few details I might be missing. But I started to spin on an idea, maybe someone can give advice, how could this be accomplished.
I have a max-craft wizard (Let's avoid the level and such, just focus that the crafts a lot, for simplicity. But if some required detail is needed, can bring it out).
A thought I started to do, is that one of my companions is quite an able fighter, also wearing a full-plate. It's currently just masterwork, but will be enchanted soon. I thought, is it possible to perhaps make a construct of the armor (maybe just even medium animated object. So I could tell the animated object few keywords, that the fighter says, that the armor "dons itself on him", so that he does not need help and maybe cut the preparation time. So when it dons itself, the fighter is just wearing armor. But if not wearing, the armor can just guard or do simple tasks. No real fighting intended, but if worst comes to be...
But well, there is one catch. If I choose to, I can tell the armor to not un-don himself and perhaps just keep the meatbag inside him and if I even want to, walk into water to drown the carrier. Or just make him attack some innocent person and blame on the carrier of the armor (because, come on, full suit of armors don't walk). Not saying that the one inside is my "companion", but not drawing it out either.
I once read something similar somewhere, but can't find it anymore and maybe there is a clever way to resolve it. Ofcourse I know, the cost is going to be a bit high, but that is currently secondary.
I believe you are thinking of the armor construct option under building and modifying constructs.
the only "downside" to this is that strictly speaking the armor would absorb all damage directed at the fighter until it's destroyed. You could probably work with the gm to allow you to treat it as normal armor in this regard.
