The only time I was ever scammed was when someone lured me to the mole caves and told me to give my tinderbox to him. Only lost full rune, but that was a lot to me back then.
You're thinking of the rockshell plate, this was the release of the granite plate. I personally won't buy granite legs, because rockshell legs look similar, are better, and cost a fraction of the price (not everybody can afford legs like that).
