I saw a leather in the CS. I'm really looking for one of the lvl 5 str ones. I already have everything I need and even bought a Gem for 30k, not realizes the pink recipes aren't free. I agree with Vildax, you most likely need a lvl 5 to farm the lvl 5 recipes. I know at least one person in the forums who found one, but won't spill the beans.
