Praxic Professional/Yellow Crystal for Praxic Blade

If anyone is wondering how to get the Yellow Crystal for Praxic Blade or confused at all, here you go; farm Vanguard Orders until you get a legendary, keep doing legendary orders until you get an exotic order. Once you get an exotic order, re-roll it until you get Praxic Professional.
