Anyone who has read bestiary 6 or found it's info trickling online may have come across Mammon master of averice.
And his masterpiece, probably the most powerful item in pathfinder the argent prince, now I'm not particularly well informed on constructs. So this is a guess but I'm pretty sure you can't within the rules make a construct like the Argent prince, (it takes mammon a year to make a replacement).
But I was wondering how close a person can get, with and without mythic rules.
I suspect not very whilst remaining medium. Also wondering if other people have ever tried this or homebrewed s similar thing or GM fiat made something similar for whatever reason.
