So... Say we make an orc and put points into his racial that makes him fast. We then craft him medium armor with the mundus stones trait and give him the steed stone. How fast can he run? Faster than a horse? Would he be the fastest orc in the world? I might try this with the fattest orc in the world.

the fattiest and fastest orc in the world sounds like a sight to behold , i would warn though there are a lot of stat caps and im pritty sure movement speed will be one of them unfortunately . but keep the dream alive !
