Supreme Inquisitor's Robe (https://torf.mmo-fashion.com/supreme-inquisitor/)
It's been my Assassin tank's gear since shortly after launch. Still haven't found a chest piece that better suits Sanctus.
EDIT: PS mind the piece apparently is worth a fair bit of credits these days. Keep an eye out though and you might find one for a bargain, or at least be able to haggle into a better deal.
